Alternator Question
« Reply #15 on: September 06, 2005, 08:43:04 am »
Hey fspGTD, can you elaborate on your alternator and Transpo self-exciting regulator?  I want to use my WVO Jetta along with an inverter as a low-wattage (TV, radio setup) generator for tailgating, but with the way the alternator is designed it will leave me with a dead battery very quickly.  I searched on the Transpo site and the only regulators they list for our alternators are NOT self-exciting.  Details please?  :D

Thanks,
Ray

It's a totally different alternator I put on there that is self-exciting, made by Denso (as in Nippon-Denso).  Denso is not an OEM for volkswagen.

When my diesel's alternator went belly-up I installed a single-wire, self-exciting alternator (intended for a GM application) in place of the dedicated diesel alternator. I bought it at NAPA for $90. I had them install the smallest pully they had (about 2.5") so that it would start charging as soon as the engine turns over. Works beautifully - I get 14 volts at dead idle.

Do you happen to have any info on that alternator, like a part number?  My local NAPA people just punch the make/model and call it a day, they don't know anything beyond that.  Also, are you talking about the 90A or the 60A alternator?

DOH!  That probably won't fit in my 90A spot then.

I don't think there's any physical difference between the 60A and the 90A. In any case, I had to shim the alternator into place with washers, so if you can fit the 90A in there I'd give it a try.

Sounds like a standard Delco 15si set up as a single wire. The 15si was used for a lot of years in almost anything GM sold, so a core shouldn't be a problem.  Any starter/alternator shop can do this, and you can run a "W" terminal off this alternator too, I have one that came in my perkins powred chevy truck.

BTW, the alternator listed didn't even come close to fitting.  The mounting points are 180* apart on the alternator and the top mounting arm needs one that is about 120* or so.

You could modify the mounting arm................
