Denso Internal Voltage Regulator Alternator Conversion Questions
Ok, I've read the tech, and the GM threads, and just want to make sure I'm doing this correctly when replacing the external VR alternator with an internal VR Denso....
So, 1983 (Build date 9/83) Australian spec. FJ45 Troopy. 2F motor w/non-electronic ignition (points, coil, external ballast resistor coil).
External Voltage Regulator p/n 27700-15011. It appears that both the OZ spec. and US spec. 40 series use the same VR, from the EPC and US spec wiring diagram.
This year's VR has six wires:
From a 1982 US spec. wiring diagram, which shows both an internal VR alternator, and an external VR alternator, using the same VR:
From left to right: White/Black to E terminal on original alternator, White/Red to ?, Yellow to L terminal on original, Internal, US spec alternator, White/Blue to N terminal on original alternator, White to ?; and White/Green to F terminal on original alternator.
The old alternator hookups look like this:
The new alternator hookups look like this:
From what I can figure out....I will need to attach three wires to the new alternator:
The Yellow wire would go to the L terminal.
The White/Blue wire goes to the B terminal.
The ? wire goes to the G terminal. (Looks like it goes to ground on the diagram.)
And...should I run by Radio Shack on the way home and pick up a diode to prevent voltage drain? If so...which diode and where will it go?
Can anyone point this electrical village idiot in the right direction?
