After (finally) getting the broken bolt out of the alternator mounting bracket, I'm ready to proceed with installing the new alternator.

When un-installing the faulty alternator, I failed to document/draw what connected where.

I figured, (go figure), that it would be easy to remember. Two of the wires go on the engine block side of the plug, the plug plugs in, and the remaining wire connects on the opposite side of said plug. The Haynes manual doesn't help a novice like me, since I don't read elec schematics.

Any/all help appreciated. I'm posting a pic of the back side of the alternator and a pic of the four connectors.

Thanks!

First Pic

2nd pic

One of the connectors appears to be part of the hose that is underneath it (at the top of the pic). It kind of blends in in the pic, but obviously is not part of the braided hose.

on page 146 of the haines manual fig 10.4 shows at the top the connect up position for the wiring.

accepting that the two pin plug will just clip in, then

at post A you should connect up wire white with red line.

at post E you should connect up wire black.

both A and E posts are clearly marked on the rear of the assembly. E is a bolt head, secure under.

good luck

but what about the 4th wire (at top of photo, APPEARS in the photo to be resting on top of braided hose)

this connector looks like it has a resistor? or fuse? or something... does it go on the same connection as the black?

Is it a ground?

If the out put wire is black it will piggy back black on E in this situation.

!

Mine looks different.....

has internal voltage regulator... maybe that's the diff?

MDyer - That resistor is a noise suppressor for the radio. Internal VR types have that built in inside. You only need to ground it to the E terminal.

Not that it matter's any, but that is a "capacitor", not a resistor. It's function is to suppress noise for the radio as described.

You'll notice several of those in the engine compartment of early (240)Z's. One is the "condenser" mounted on the distributor, and there is usually another mounted on the driver side inner fender near the ballast or coil.
