alternater queston for you

[bobmack]

I purchased a 74 beetle, it has a Bosch alternater with a external regulater. there are 4 wires coming out of the regulater (mounted under the back seat, driver's side) The wires are going to the engine compartment. I can understand that the b+ is on the larger post and there is a d+ connecter on th alternater.Here is the sticking point the Bently publications mention a multiple connecter on the alternater. This alternater has no such animal. lt only has two connection points (B+ and D+)where do the other wires go that are just hanging loose.What and how many wires are connected on the alternater with an internal REGULATER?
if anyone out there can shed a light on this, please do.

Thanx in advance----bobmack

what does your alernator look like? does it have a large diameter end or is it the same diameter at both ends? if it is the same it has a generator. also check out this fourm. they can help you out. www.shoptalkfourms.com

Thanx for your answer bugman. It is definately an alternator(bosch). It has a larger post that holds the B+ wire with a small nut, the D+ wire is smaller and connects via a female connector that just pushes on.The regulator is made by motorola and has a red, green, brown, and blue wire coming out of it.These wires are designated d+, df, d- and no designation on the 4th.These wires are short, going into a connecter that in turn that goes to the engine compartment.As I stated in my earlier post, the D+ goes to the smaller spade connector on the alternator along with a larger wire from the Batt that goes to the B+ post.It's the two wires (DF and D-) that are just hanging there that has me stuck.

that sounds like the internaly regulated alternator. go to the web site i mentioned earlier ask someone there or do a search i'm sure someone there has a wiring diagram for your set up. they deal with aircooled vw's only and we have qutie a few members there that can assist you better than i can.

You can check Speedy Jim's Web Page. He's an absolute genius when it comes the VW electrics.
