Re: 91 crx si battery drain
I had nothing but problems with Optima in a healthy car.
I have an '88 Prelude with a similar issue, but it's gotten so bad that the lights will flash on and off, sort of pulsate, when the car is running. Everything power operated pulses at the same beat (climate control, throttle response, lights, power windows).
If I leave the car sitting a couple days with the battery connected, it will drain the battery.
I know my car has a bad voltage regulator. This is number 3 or 4 now (same number for batteries btw). I just haven't found the ground issue (which is what I was told it likely is) that is causing the car to eat voltage regulators and batteries.
