RE: [DML] RE: idle flux / stall / pickup line?

If your alternator is dropping low enough in voltage to turn on the battery,
then that's to low. At that level you can go below battery voltage and the
car can die, and the FP will slow down to a crawl, lights will dim and fan's
will slow down. I would increase the idle to 900 RPM's no matter what
alternator your running and see what happens. Also, turn off any major
current draw items such as the cooling fans and the blower motor and lights
and see what happens. But, either the alternator could have a bad regulator,
but most likely it's not because it works fine with a little more RPM's .
This is why we turn a smaller pulley for our alternators to raise the TOV
( Turn on voltage ) at lower RPM's.The cars really need to be idling at
about 900 RPM's to generate a little voltage and current and be at TOV or
above..

No battery light unless it actually stalls. Mostly it just does the
drop/rev/flicker bit.

I still havent installed your new fuel tank baffle assemby. I guess that's
next
on my list of "to-dos" unless my problem is something else besides a faulty
pickup line.

Shannon, What is happening to the electrical side when this happens. The
fuel pump is an electric motor. When Your idling and the voltage drops the
fuel pump will slow down and your fuel pressure will drop and go down also.
It may look like a pump/fuel problem, but you said it was ok when you race
up the engine a little. Then voltage also goes up from the alternator and
your ok. Is the battery light coming on. If so then the voltage is dropping
so low the car thinks you have shut it off.
