64 R50 generator problem

[johnab9hh@att.net]

I've had multiple gen problems.
My red light started flashing on. I found that the brushes were worn to the end.
I ordered a new set from MAX. after the third type shipped to me, i had a set that fit. They were hanging up in the carrier a little bit, so i sanded slightly with emery cloth, then cleaned the brushed and carriers with alcohol on swabs.
The light then went out.
When I would run the engine up to about 3k rpm (guessing) it would open the fuse to the battery. 
I put my good fluke meter to measure voltage. about 7.2 volts steady.
I put my good fluke dc ammeter on, about 2.8 amps, steady.
When I slowly would it up, everything was steady, then POP, the fuse to battery plus would open. I could not record the peak.
I looked for corrupted wiring, since I was in there, but found none. 
I have a new voltage regulator, from Vech's old stock at Max, but I don't want to throw parts at it. I'm not that type of guy. 
Ive read the Doug Rinckes manual, but it seems lacking in this area.
Thank you for your time

Fuse size ?

I agree, what amp fuse do you have installed? It may not be heavy enough.

[johnab9hh@att.net]

20 amp, and it makes an audiable POP
Any Clue?

I agree, 20 amp is a big fuse for the bike. You have a DEAD short to ground somewhere.

Thanks for the tips. Ill start checking. But its odd that this started IMMEDIATELY after replacing the brushes.
