I don't have your schematics, so can't help you. But I'd be looking at the power feed to those devices, you may have a relay with some burnt points creating a resistance and dropping the voltage. This voltage could be checked with a digital voltmeter. Many vehicles also have a small computer or part of the body control which also is involved, for instance, automatically locking the doors when your vehicle exceeds 10mph, or opening the door locks when you put it in park. Remote start controls, can also control windows.
I just did a quick internet search for Voyager service manual, and came across these guys. Personally, I have never used them so don't know that their manuals get down to the electrical schematic level that you need. I've used HelmInc for online manuals successfully in the past, but they don't carry Plymouth manuals.
You want to find a set of manuals which gets you to a level of detail like this posting I have on my carspace that I did for someone else where I had the manuals, and was able to mark it up for them. Normally you'll only find black and white. Hayes and Chilton normally don't get down to that level of detail, you typically need some sort of factory service manuals which also need electrical schematics.

I didn't receive any mail from you, so don't know whether you haven't sent it yet....or my email at edmunds carspace isn't working correctly.
Can you let me know if you tried to send...thanks.
The Lexus dealer will replace the cable for $4,000 plus $1,400 in labor. I guess it must be made with gold wire. :sick:
She then took it to an independent shop that works on Lexus and asked if the cable could be repaired. They suggested that she try an "electrical shop", but that there may be a risk of damaging the tranny.
She is located in the Seattle-Tacoma area, so there should be lots of "resources" available to her.
Thoughts, ideas, suggestions?

Another issue is electrical fire and the liabilities that go with that. So the dealer is playing it safe by repairing the entire subharness, from one connector to the next. This is no doubt a tedious job in itself and I would imagine the harness is not cheap and must be special ordered.
You can shop it around but be careful what you wish for, you may get it.
You might try www.nissanhelp.com, sometimes they have downloadable manuals.
If you can find a set of electrical schematics in electronic format, I'll help you with the trouble shooting if you need/want.
You should have everything you need to isolate and fix your problem.
But, no idea if this your problem.
Oh, and a battery cable that failed will also shut the car down.
The alternator fuse does usually protect other circuits besides the alternator, let me try to give you an analogy which isn't the greatest, but you may get the concept. Lets assume you have a savings and checking account at a bank. Your paycheck normally gets deposited into your checking account, and you pay your utility bills each month directly from your checking account. In a normal month, you may have zero dollars transferred between your savings and checking account, but lots of activity within your checking account.
That fuse is between the battery (your savings account), and the checking account (your alternator). Hanging off on that alternator circuit side could be a number of different fused circuits, all capable of drawing off current (those utility bills). As an illustrative example only, lets say one of them might be a fused headlight circuit. When those headlights are on and the engine is running, the power is coming directly from the alternator, it does not pass thru that 90? amp alternator fuse. Only if the engine wasn't running and the alternator wasn't making power, would the required power come from the battery.
So the current going thru that 90? amp fuse, is more like the current that is charging back up the battery. Back to the analogy, when you buy some furniture you withdraw money out of your savings, and then over the course of the next couple of months you slowly fill your savings account back up.
In a vehicle, some circuits are wired on the battery side (typically like the starter motor), and some are wired on the alternator side of that fuse. So if you had electrical schematics, you'd be able to see which fused circuits are on the alternator side of that fuse. You should be tripping the individual fuses first before being able to draw the 90? amp and blow that alternator fuse.
If it was my vehicle without electrical schematics, here's the stuff I would probably do:
- would suspect first, anything added electrically to the vehicle, where someone might have spliced into some wires (added in a new stereo, trailer hitch, alarm system, HID lights?)
- inspect for corrosion on cabling, either on the positive or grounds, at battery connections, starter connections, fuselink box connections.
- I would then suspect electrical things that 'wear' with age. The ignition switch, which on an old vehicle has seen many cycles of turning off and on, and may have developed an internal short. The cig socket, which can get prongs bent inside, wiring on the drivers door jamb or trunk which goes thru bending opening and closing, etc.
- the next diagnostic technique I'd try is to carefully label and pull all the fuses I could find (both engine compartment and cabin. Make sure you know exactly which fuse came out of which slot, and take close up pictures if need be. Once all the fuses were out, replace the 90A alternator fuse and hopefully it won't blow. Begin putting the fuses back, starting up in the engine compartment first as those tend to be the main circuits. If your 90A fuse then blows, then you have focused in on the problem area. This can be a very labor intensive approach.
A set of electrical schematics could save you hours and hours of work, so personally, I'd be buying that first.
The real point of this post, expand your diagnostics beyond thinking you have an 'alternator' problem.
Last Friday, torrential rains, car outside all day. Nav unit was again flickering on and off, with greater rapidity than I have seen. Over the course of 15 minutes (before car warmed up/dryed out I guess), it probably flickered on and off 75 times. Maybe 15 times, the flicker was accompanied by the ABS and Brake indicator lights on the dash flickering on the dash itself (i.e. as far as I know, it was just the indicator lights flickering), and the gas cutting out. These are super quick flickers, the gas cutting out was noticeable, but over so quickly it didnt seem overly dangerous and I crossed my fingers and drove home.
I am very concerned I got ripped on the repair work that was done. The tech essentially admitted to me that there was no thorough testing of the electrical system. Sounded like he stopped at a visual inspection of the wires/connections. He noticed that by jiggling the key in the slot, he could make the power flicker and decided the ignition switch was bad. He recovered a code that had led to the check enginge light being on, which reported a problem with the main computer control system, which he said was hopefully just from the power spike. He reported that he "used a hose" on the car but was unable to recreate the problem. He took the car for a "test drive" today (no rain today.) So "maybe" it was the ignition switch. I am getting a bill for $390 for this!
Hope I'm wrong, but my guess is that the next time the car is out in/after heavy rain, I'm going to be cursing up a storm when the problems reoccur. Most of my drive to work is a busy highway, so its probably not to safe either.
What the heck? Any thoughts would be greatly appreciated.
Has anyone tested for the following?
1. Is there a spark at the plug when the engine cranks?
2. Is there a pulse at the injectors when you crank?
3. Is there fuel pressure in the fuel rail?
Any good mechanic has the testing tools for these 3 tests, and the "yes/no" answer will tell you which way to proceed toward a solution.
Passenger electric window stopped working on my 1999 voyager a while ago, Recently driver electric window stopped working. it looks like Chrysler have some major electric problems, I woul appreciate any feedback.
Sounds like you need to get to the underside of your drivers switch to check whether it is supplying voltage to the window regulator/motor assemblies, or not.
thanks
Check for spark.
How did you get rid of all of that bad gas? Any rust on the main crank bearings?
compression should be good .. is all new and torqued
what about the sentry key imobilizer module in the ignition switch ? its a round ring module.. would that have something to do with it ?
Are you getting sparking at each of the spark plugs.......?
What is the fuel pressure...............? Are the plugs wet with fuel when you take them out of the head?
And just to clairfy, when you say it sounds like it wants to turn over, but doesn't...do you mean that the starter is engaged, the starter is turning the crankshaft of the engine, but it is not starting to run....correct?
If this was what was actually said - it's BS.
What, you can't drive a car from California to Ohio?
And, by 2000, all cars probably met the California emission standards.
I have a 1996 Jimmy that I put an electric over hydraulic plow on. I put a second battery in it to help with the draw. I used it all last winter and when everything was running (lights, defroster, rear defroster, rear wiper, front wipers...when I actuated the plow...it would draw down to 9 volts at an idle to 1000 rpm. I decided to put on a larger output alternator for this coming winter and bought a 155 amp unit and also the recommended beefier wiring kit with a 175 amp fuse in it. I installed everything and ran the vehicle with everything going and actuated the plow several times. It still drew down to 10 volts but recovered much quicker. I shut it off and since it's just used for plowing, I didn't start it again for a week or so.
Recently, I started her up and immediately noticed that the voltmeter was registering about 9.5 volts with no load on anything. I called Napa and had them ship another one. I took my new one in and the guy bench tested it and said it was good. He also tested the new one they got for a replacement and found it to be bad so he ordered a third one. I installed this one and it worked fine. I started it up the next 3 days in a row and it was charging just fine...but the 4th day, it did the same thing. When I started it up, it wasn't charging. Something happened to both alternators between the time I shut off the vehicle and the alternator was charging...to the next time I started it and it wasn't.
I believe I should have 12 volts at the charge cable end at the alternator at all times...I do. Also, the "L" terminal coming out of the harness at the alternator should have 12 volts when the ignition is in the RUN or START position...I can't confirm that. I don't have a test meter...just a 12 volt trouble light and I'm not sure I'm making a good connection to that small pin but I had these conditions before I installed the second alternator and it worked for 4 days.
I don't understand what has happened...why the new alternator will work for a while and then just stop working while the engine isn't even running. I just replaced the original 105 amp alternator with a higher output one...and I installed the wire upgrade kit that goes with it. Both of the alternators have "failed" since doing the changeover. I have rechecked my ground and all wiring. Something is happening after running and then turning off the vehicle...with the first one it was the second time I started it up and it just wasn't charging. The second alternator worked for 4 start-ups and on the fifth...just wasn't charging. Neither one of them "quit" AFTER starting the engine.
What does that "L" pin go to? Does it have something to do with "exciting" the regulator? I think I read that it could have a resistor in the line somewhere. What does it look like, where is it located, and how do I test it? Can you enlighten and help me...PLEASE? :confuse:
Thanks,
The hardest problems to find are randomly intermittent ones. Your radio and a/c problems sound like they occur fairly regularly, so they should be easy for a good electrical guy to zero right in on the problem.
If the fog lights were factory, hard to imagine they would create some sort of electrical problem that was causing your vehicle to die. If someone else installed them aftermarket, then no telling what they did to the wiring to get power.
They are factory lights, but for some reason the light case will hold water. I guess there is a crack or something, but I can't see it.
I'm trying to keep the car going for at least another year, but I was just told the radiator has a hairline crack and the cad. converter is going out. I do the regular maintance, and I know it's a good car, I guess the one I bought just isn't wanting to hold out.
