High idle while lights are turned on (1988 Corolla FX-16)

I just recently fixed my 1988 toyota and it is running great. I might
be able to get a few more years out of it..... I noticed that while
the lights are turned on the engine will idle higher than normal. As
soon as I turn off the lights, the idle will go back to normal. Anyone
out there that might have an idea as to why this is happening???

Yes, that's the 'idle up' circuit, same thing happens when the
compressor for the air conditioning comes on...perfectly
normal...

FX16, huh...

I think you need to get rid of this car. It's beyond help. For a mere $125
I'll take it off your hands so it won't bother you again...Uh, how many
miles on the engine?? ;)

As far as your problem, you may have a weak alternator, or a battery going
flat. Try a different battery; the alternator is trying to make up for the
lack of current required when you turn on the lights. The battery should
be supplying the bulk of the current for the lights, and it doesn't appear
to be doing so.

Hachi, I hope you're just joking with your explanation
there?...:)

I, too, think that he should sell it to you cheap...
