Alternator

[LGAFF]

What alternator options do we have, new 90 has a voltage jump with the turn signal on and tonight volts dropped significantly with the headlights turned on.

CS-144 it a stout Alt.. no sense to change to something other then the OEM replacement when replacing it.

i know i am going to get greif over this but it has been a great alt. for 5 years .i got an autolight rebuild from kragens for 140

A local alternator and starter rebuild guy here in DesPlaines rebuilds mine for $95 with 1 year warranty.

Agreed, rebuild your original :dancing

Could very well be the alternator. That said, I wouldn't rule out a connection, at this point. Just to eliminate possibly having to dig out the alternator, I'd wanna see what the voltage was at the battery with the turn signal on, and then the lights. Normally, it should be around 14.7 VDC (cold). If the alternator/regulator is going south, voltage will be "something" other than a steady 14.7ish with the lights and or the turn signal on.

How-some-ever, if there is a ground or B+ connector issue in the wire harness between the battery and the various ciricuits, the voltage at the battery will remain more or less constant while the voltage (on the other side of the fault) will drop significantly.

It may well be the alternator/regulator, but I'd wanna see voltage fluctuate at the battery before I pulled the alt.

Just my 2¢ - and prolly not worth that!:dontknow:

The voltage is fine, until the turn signal comes on....drops to 12 and back to 14.7 as it blinks. When headlights come on there is a major drop down to 10 or 11.

Did you have the battery checked yet?

[LGAFF]

No but it s holding a charge....I guess I will check it out, but I would think it is the alternator.

well the battery is easy to pull and have checked..

Start simple.....

Also how do you know the actual voltages?

are you using the highly calibrated OEM dash gauge?? :p

Just installed an Alternator for a Z brother in our "VA plenum Pull" @ Michael R's home.....

Glen paid $130 for an alternator from Kurt White (wasn't OEM, not identical to original, but worked).

Installation wasn't too bad.

Just a few bolts and had to move some hoses.

I'll get you the "brand" that we used. I think you can purchase it for much less @ any auto store.

When the headlights and blinkers are on the volt meter is swinging back and forth bigtime.

the OEM voltmeter??

what about headlights only?


I am thinking there is no issue, I am pretty sure my 90 does the same thing, but I cannot run ot and check, it is still an hour away

Well after after discussing with Jeff sounds like the Alt is fine, must just be a difference between the 90s and 92s.

[GOLDCYLON]

Well my 91 doesnt do that either Lee. Maybe some other MY 90 owners can chime in here as well.

I went and got my 90 today.. so I called Lee while in the car.. mine is just as he describes.. I think it is a non-issue

pull the battery, remove tray, then clean and remove paint on the frame. The 90 model has a TSB for this. I did this on my 94 too. It helped with the dash volt meter bounce.
