65A generator

#1

Post by 56/58/65 Pan » Sat Jul 03, 2010 1:16 am

My generator is a 12volt model 65A . My question concerns the armature and field studs. Just recently got this bike and
the generator has never seemed to work. The way it is currently wired is with gen terminal from regulator going to the stud that is pointing to the front tire and the field terminl from the regulator going to the terminal that is pointing up. Is this right. The clymer book, which will soon be taking up space in the bathroom, shows just the opposite. Looking from the back end of the regulator there appears to be a big A stamped near the left (front ) stud. Help! Bill

Sounds about right to me, the "A" standing for armature, you can always loosen the band on the gennny and give it the sniff test. If it has that burnt electrical smell, it's toast. Usually the armature. Otherwise, time to do some more troubleshooting,

I've never seen anything in any service manual about the sniff test, but I've used it for years, and its ALWAYS accurate. :P

Model 65 generators and model 65A are opposite from each other as to the terminal marking. Be sure of what you have. And Clymer manuals are best left to lining litter boxes and bird cages!

I'll do some more testing, I know it is stamped 65A but still not sure which terminal is armature and field. The clymer book is in my bathroom, but I didn't say it was for reading! Thanks for the help. Bill

Robbie, Thanks for the tip. The diagram inthe clymer book is for the model 65. Mine is a 65a which shows an A and F above the terminals. Opposite of the 65. I Think i will try the sniff test. If it smells ok i will try to polarize. I have had the battery out several times and changed wires to 12ga. from regulator to gen. so I guess I should do this. What size wires should be on the generator. previous owner had it wired with 16Ga. and they seemed to small to me. Thanks, Bill

The generator is rated at 10A Max, so 16Ga wire should be adequate. The 12Ga won't hurt anything, as long as you wired it up correctly!

I resurrected this thread because I have a similar problem. My pan has a 55 motor that was upgraded to a 12v system. I don't see a single identifying mark on the generator. Is there someplace I should be looking to identify this generator? Under the end cap? Under the strap?

The voltage regulator has almost no markings on it, and seems to be a repro of one of the Delco Remy types with two terminals at one end (one is marked BAT) and one terminal at the other end. (This appears to be the "Look-A-Like" regulator in the VTwin catalog - part no. 32-0071.) Other than BAT, there is no writing anywhere on this regulator, including on the bottom.

I've had the battery unhooked several times while I was replacing an ignition switch and can't figure out which terminals on the regulator to use to flash the field coils on the generator. Palmer's book isn't any help, since it talks exclusively about 6V generators. I also have Kirk Perry's book, and am using the wiring diagram for 48 - 57, which identifies the forward terminal on the generator as the Switch Terminal and the rear terminal as the Relay Terminal. The wire from the relay terminal goes to the rear terminal on the regulator, leading me to believe that the rear terminal is "A", which leaves the front left terminal being "F". The wire from the forward terminal on the generator actually does go to the switch (terminal 2). To flash the generator field coils, I connect a clip to the BAT terminal and briefly touch the other front terminal ("F"?) on the regulator.

I still need to test the regulator and generator, but before I start the tests, it would be a good idea to know for sure which is the A terminal and which is the F terminal on the regulator. Any help here would be greatly appreciated.

Thanks,
Mark
