Quick question.

My '86 tends to bog down slightly when I am using a heavy electrical load. I noticed this the other day playing with the power windows. The RPM drops a hun or two. I also noticed it today with all the wipers on.

I know the alternator was replaced recently but the batter the previous owners put in looks very small.

Would a larger battery cure my ills or is it something else?

Thanks,

Warren

I'd check and clean all contacts at battery, alt., starter,etc.. Then check alt. output and voltage at battery. My guess is a bad ground.

100-200 RPM is very low. Sounds like the alternator is having to work too hard to make all that power. The EFI system should be able to keep the revs up though.

Is it an automatic?

Thanks for the tips.

100 - 200 RPM is how much it drops from idle. I'd say just from the tach that it drops to about 600 when under load and in gear.

Yes it's an auto but not for long. I'm putting a G52 in it soon.

Hey Skydigger,

Mine tends to do the same thing - power windows, sunroof, etc, all make the rpm's drop slightly until I am done using them.
