I am finishing the alternator upgrade from MSA on my 72 240. The PO had already installed a 50 amp Hitachi unit but had made no changes to wiring. My question is do you have to switch over what I believe is an external condenser from the previous unit to the new one? The new alt did not come with this part, and I have searched to try to find anyone else with this problem with no answer. These are too expensive to burn up so I want to get it right. The pictures show the wiring before the swap and I have highlighted the part in question.

The condenser it there, from what I understand, to cut down on radio noise. I don't think the lack of it would cause any problems other than that. If it were me, however, I'd install it on the new one.

Thanks, I think that I will go pick up a new one while I'm at it, it looks like they are pretty cheap.

I have two of these 50 amp alternators, one is NIB the other I just pulled off if anyone is interested.
