We have a 1991 Toyota MR2, which from day one,
has had a battery problem. The car has only 10,000 miles on it, and even when we drove it
often, we would face a dead battery. Now is is
in a Toyota dealership garage, being looked at for
an electrical problem. After many days, they have
not been able to locate the specific location of the problem. Has anyone else faced this? Does
anyone have any solutions. Thank you for any

    I haven't started using my MR2 much YET, so I haven't looked into the problem but my guess is it's the alternator. When I was changing my timing belt I touched my alternator and noticed it was hot (the engine had not been on) Please post or email me if you find out the problem!

    I don't see why they can't find the source for a dead battery...if the system is charging properly on their testing unit, (under load) then replace the battery, adjust the alternator belt, and check quickly for a battery drain. If there is no drain and the alternator is charging properly under load and you have a new battery in there, your problem is solved.

    Any battery more than 3 years old is very suspect.
