Volvo 740 electrical gremlin help
A 1988 740 GLE with 190K miles. The alternator tests good (charging the battery), and just put in a new battery.
Indications: Above 2000 rpm, the idiot lights on the dash come on just as if there was a alternator problem. Below 1000 rpm the lights come on very very dim. Between 1000 and 2000 rpms the lights stay off.
