Loop Alternator Conversion

[wirespokes]

Looks like I'm a little late to this party. 

Greg Field used to sell the mounting brackets and I guess a whole kit including alternator. Other places used to sell the mounting bracket, but not now. Looks like I'll have to make the bracket myself.

Are there drawings anywhere I could access? Any idea where I could locate the bracket new or used?

Harper's has them.

Joe Walano "The Guzzi Doctor" may also have some left to sell.

I installed one on my police Eldo and the hole for the oil line was too high, so unless they've moved it, that needs to be modified. Edit: one other thing I did: removed the powercoating on the underside so there would be a good ground to the case, and removed it also where the alternator contacts the bracket for the same reason.







Greg Bender sells a harness. I bought a Nippon-Denso copy alternator on ebay.

Charlie,

Did the generator light work correctly with the alternator that you linked??

I have a Denso copy for a spare that the light does not work right.

So far it is.

I built my own alternator bracket out of 1-1/2" flat stock and 1/4" pipe. I'll have to search around to see if I have any pictures. The bracket looked sort of like the USS Enterprise

When I bought my current ‘71 police Ambo, the seller had a new Field/Nolan Alt kit still in the box.  I didn’t hesitate to buy it from him to add to the refurb (to include new cylinders) at Charlie’s place.

If it's working, it will keep working. The copy I have did not make the light work correctly out of the box. I don't remember the exact issue, I think the light stayed on even though it was charging?? BTW police dash on both bikes with the pull knob for ignition.

Might have to pick up one of those. Thanks!

I'm considering making my own bracket - not quite ready to spend $140 plus shipping on one.

How much is your time worth? Figure in the cost of materials as well.
