Default Regulator Issues

Here is a good story about panheads.

A riding buddy has a 63 pan that has over 360000 miles on it.. He was having trouble with coils so I lent him an old Snap-on coil tester that I own.. I should mention that for the last number of miles, could be 100000 that he found if he could not use AGM batteries as they would just fry and die.. Also he had to mount the flooded batteries in a box with a tray to catch battery acid as they would boil over. Anyway, he tried the tester and it worked well enough for him that he was able to find some good coils for the bike. Later he complained that the coil tester somehow killed the regulator so he had to replace it..

Me? I 'm skeptical.. So I asked for the regulator to see if I could see what was wrong..

3 pics,

1. The coil tester
2. Correct drawing of the regulator
3. Picture of the regulator..

From the pic you should be able to tell what was killing AGM Batteries.

How'd he not see it? Did he pull the cover off when doing the test?

At that point he was replacing the regulator already. I think what actually failed was the cut out relay stuck but he had a fuse on the battery ground wire and it blew so it didn't hurt the generator.

You would have thought that a 6v headlight that is brighter than a LED would have been a clue.
Any idea if it was over amping or over voltage with that washer stuck in there?

He never runs with the headlight on..

It's the voltage coil. You can tell because of the small wires..

The HL brightness from over charging common with the 6 volt cars i grew up with stuck regulator

junk yards would sell in NYC 6 volt cars for 40 bucks and a battery was another 5 to 9 bucks - as a kid look for a crash out if state car and grab the plate
