grabatire.........many times, instead of replacing the burned points, shadetree mechanics will "jump" the ballast resistor for hotter sparkies and eazier starting. Unfortunately, they fergitt to remove the jumper and MELT the insulative tar inside the squarecan coil and will no longer start 'cuz you end up with weak sparkies and BAD coil.
Heres the deal on extra resistor. Many "bubba" conversions are done on the "cheap". Use the original ballast resistor plus a 12V-to-6V conversion resistor in series like flashlite batterys. (resistors are cheaper than new 12V coil)
As fer voltage readings, about 4-volts at top of the 6V squarecan coil and about 10-volts at top of new 12V squarecan coil (with the points CLOSED) .........Dell, yer self-appointed sparkie-meister

I had just talked my Dad into buying an old John Deere B with 6-speeds ahead and I was real proud of it, except it was a little smaller than the Case tractor that we normally
