I might, sometimes those are totally separate books. In that I have not been paying attention (you all are over my head again) I'll need the pertinent details - year, engine, etc.
then I can look. Mary
I bet Mary has a wiring diagram. I probably do in a service manual too. Both my g0bodies read lower on the gauge than at the battery.JCOn Wed, Nov 24, 2010 at 12:31 PM, Chris Lindh <chris@xxxxxxxxxxxxxxxxx <mailto:chris@xxxxxxxxxxxxxxxxx>> wrote:Yes, I had previously used the brown wire that originally plugged into the SI alternator. I had to extend the wires since the V6 had the alt on the passenger side. I do not know where that brown wire originates. I changed the "L" (lamp) exciter wire to a wire coming from the HEI plug with a 470 ohm resistor. I installed the new CS130 alternator and I'm back in business: 14.7 volts read at the alt. When the alternator is "on" with key turned you can hear a high pitched sound, the same as the previous CS130 (before it died). I hope the resistance is correct... One snag, I had to clock (rotate) the alternator housing so the stud would clear the valve cover. I don't use the rear support, so this is not a problem. It's a bit more tidy with the alternator plug hidden.

A 50 cent bulb took out the alternator?
