now, riddle me this: after i got to starbucks and gulped down a double shotted espresso, i walk back to the car and fired her up. light stays on, like before. parking lot is empty, so i give it a "spirited" takeoff. and the damm light goes OUT !@*!! so i pull over and put the multimeter to the terminals: • 12.95 V at idle • 14.04 V at 3k rpm now it's working again ?!? (IMG:style_emoticons/default/WTF.gif) i suspect i either have a lose connection somewhere or the voltage regulator is on it's way out the door ... (IMG:style_emoticons/default/blink.gif) Andy |

QUOTE(SirAndy @ Jul 26 2007, 01:26 PM)  QUOTE(Dr. Roger @ Jul 26 2007, 01:00 PM) My internally switched alternator has but one wire connected to it. It is tickled by low voltage from the thick wire coming from the battery. Does yours use 1 thick wire or are there 2 or more wires? What model and year is your engine? i'll have to take the shroud off the motor to get a look. there's no easy access to the alternator. '95 993 3.6L motor ...

I seem to recall that a bad battery might cause this.... (IMG:style_emoticons/default/confused24.gif)

In the interest of helping someone else out, I will admit my brain lapse with my -4's charging system.
After going through two new Optima redtops and swapping my OE alternator for a new one(which sucked) It took me a solid day of lookin and head scratching till I plugged the alternator lead back into the relay board. and Low and Behold she lived. I feel much better with that off my chest by the way. |

Andy,
Before I dug in and removed anything I would just do some manipulation of the harness in the engine bay and any other related areas. Clearly its possible theres a skew some where that may show up. I would do it with the engine running so you can see any changes on the fly. Maybe have someone with there eyes on the dash or a dvom. I don't see hammering the throttle shaking loose an internal alternator problem but surely a wiring issue.. would be effected by vibration and engine twist. |
