Z alternator wiring
This is showing how to install an
internally regulated ZX alternator on a early Z with an external
regulator. You only need 2 things, full time power to one of the spade
connectors and the ground wire from the idiot light (it's on the gauge)
going to the other. Both of these are at the plug-in for the old
external regulator. The below pictures show which spade needs which
signal and the other shows how I scotch locked the wires with the
correct signals to the correct wires going to the alternator at the old
regulator plug-in part of the car's harness. Use a test light grounded
to the engine to find the full time power and the idiot light (The
idiot light will glow when you probe the right wire) then scotch lock
those wires to the right color wire going to the alternator. It sounds
more complex than it really is once you know which spade is which
and you get a test light out and find the wires. Other years may
have different colors than mine, this car is a 77 280Z. Hope this helps
people figure this out.
