alternator wiring question

1974Wagon

Hello to you all. The alternator gave out on my 74 145 a week back and there is nobody left who will take on a rebuild so I bought a remanufactured replacement. It is made by Pure Energy and has model number 13038. Everything seems to be fitting together nicely (with a couple of adjustments but I am left wondering about this piece (a condensor I assume). Here is the old wiring as it was in the vehicle, filthy and corroded. The green arrow points to the piece I am wondering about

And now here is the new one wired in, without final cable alignment and adjustment. I have highlighted the screw on the back that seems to be there for the purpose of holding the condensor However, the screw has electrical continuity with the whole body.

My question is whether I should isolate the base of the condensor from the body of the alternator or if this is supposed to be the way. I have looked all through the green book without getting this info so if any of you out there could shine some light I would be most grateful. Warren

The capacitor is meant to ground itself to the bod of the alternator. (The body is like the other lead of the cap). So all's good.

You do know that you have to post a picture or 2 of your 145 now, hey. 😉

Thanks very much for the reply. I was thinking the same but great to get confirmation. I think it is actually an aftermarket thingee to stop radio crackle. (Still got the AM radio in there) Hooked everything up this morning and…bingo, we are back in business. Here is a picture of the car, made right here in Halifax fifty years ago

Your 145 looks awesome!

Yeah - that capacitor on the alternator was a radio noise suppression device.

Did Halifax-assembled cars get K-jet only or was the B20B available?

Thanks Major Ledfoot. I really enjoy this beautiful car.

Not sure about the B20B but occasionally I see a few of the old fellas from the plant so I will ask.
