voltage regulator issue (I think)
The other day after taking a cruise across town to a buddys house The batt was dead when I tried to leave,(thank god i have a kicker as well).
I had charged up the batt for 48 hrs prior to this happening. I was just about to do a generator test but I looked at the regulator first. Noticed the wire from batt+ to regulator was shorted to the batt- and all the way to the key switch. I opened the cover and looks like there was some arcing going on in there and looks like a jumper of some sort was burned up.
It was where df term is and went to a little spool lookin thing. Would this cause batt to not charge? I cant get it to charge while in bike but it will while out of bike

Hard telling if that would cause the battery not to charge while installed in the bike. The wires must have burned open somewhere along the line, so I don't know why it wouldn't charge then.
So you've probably got some wires and a regulator to replace now I presume?
Or do you have it all working again already?

Thanks, I'm proud to have served.
So no crispy wires?
From what you described it sounds like the reg is toasted.
I've seen some posts here that guys say the 66 or 67 chevy pickup reg is the same thing. Maybe you already checked that out.
Sucks to be without the bike though.

Or did the positive wire simply touch the negative (ground ) wire?
Next, replace every wire that burned up.
Now you are ready to test the generator for output and test the regulator to see if it got damaged.

I have found that there was a small arm on a spring on the regulator that kinda looks like a set of points. It was stuck on the close positon and thats when I get the contuinity from ground to the batt+ wire.When open positon it has no contuinity. Is that soposed to happen?

I am uncertain if that is normal or not, as I have never opened up a regulator.
If your regulator is a Delco-Remy you can adjust the contact points and air gap as described in the service manual.
If you have a Bosch regulator then there is no service to be done.
You fix it with buying a new regulator.
My standard practice if I suspect a bad regulator is to buy a new one.
What can kill a regulator quickly is if you removed some wiring and then started up the engine without 'Flashing the Field.'
If the generator gets reverse polarity from failing to flash, it causes the regulator points to bounce and arc which quickly burns up the regulator.
