Farmall 300 12V electrical question

My 300 was converted to 12V before I bought it. Looks like a normal alternator, must have built in regulator since the original is bypassed. Well it wouldn't start the other day. Battery seemed strong since it turned starter over pretty well, but I guessing it's the original starter. Fuel is good, but no spark at the plugs or coming out of the coil. Checked the coil and it only had a little over 5 volts, looks like it has a dropping resistor. I'm charging the battery since it only showed about 12.0 volts. I've heard you need a strong battery for the coil to work, think the low voltage on the battery is the problem? Or is the points or condenser? How do you check points, just make sure they are clean and opening the correct gap? What next if the battery is not the problem? Thanks for the help.

In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership, ... [Read Article]
