I need some Help. I just completed my 2.7 carburated conversion on my 73 914. The engine is a 2.4 case. I have installed a valleo internally regulated alternator bought from world pac. the b+ lead is connected to the starter battery wire. The d- lead is connected to the ground. The d+ lead is connected to the relay board in the engine compartment lead that goes to the alternator light then to the key switch. The first go with this it was discorverd that the alternator was bad. so A & A alternator in Riverside rebuildt it. When i picked it up they stated that this alternator had been modified from external to internal regulated. After the rebuild I have a dead battery every time the car sits. the D+ lead is hot when every thing is off and now the fule pump runs intermitentlly when every thing is off.

A nit:
When the alternator is operating, the D+/G light circuit is not "dead". Rather, battery charging voltage is generated there. Since the other side of the G light is ALSO connected to the + side of the battery (through the ignition switch), the voltage ACROSS the G light is 0, so no current flows, so no light. If the alternator is not spinning and the ignition is on, there's only +12 on one side of the bulb (the battery side), so there's +12 across the bulb, so plenty of current flows and the bulb glows brightly. If the D+ wire is hot key off, then, yes, the circuit is wired incorrectly somewhere. |
