I kinda agree on the smoke issue. For example, the battery is fried and won't take a charge on the charger. The VR does nothing- ie the contacts aren't chattering, plus bits of the wiring harness had burned/melted through.
I redid the harness and turned it on just.... long... enough.... to....see... 10V...and shut it down right away. Less than 60s.
The 10V was on an old fluke DMM that I have used to troubleshoot my 9N, my Jubilee, and my 600. I'm not really buying this analog-meters-only argument, but I picked up a simpson 260 on fleabay and will try it again with that.
No ammeter on an 841- they substituted a gas gauge. I don't have a clamp-on so I'll have to kludge one up.
I assumed it was a B circuit based on the year but will reconfirm if you tell me how. It def has a 6V regulator.
thanks for the help!
