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.

Test the battery after it's fully charged, at the terminals
12.5 volts at rest 12.5-13.0v at idle 13.0-14.0v max at 2500 rpms any higher and you'll cook the battery. If the charged battery reads low...prolly bad battery. If the battery reads low AFTER looking gud at rest....it could be the alt/regulator.... If it runs on after turning the key off....it prolly has an MSD ignition? Put a diode in the D+ circuit. |
