Magnet power

[Lexveen]

I was wondering what power the magnet has. With good, strong magnets it delivers a voltage of up to 30 volts or even more, but what current can it deliver? Has anyone measured that?

Both voltage and available current will depend on engine speed. A good magneto will provide around 2 amps at around 6 volts at hand cranking speed. Voltage and available current increase substantially at higher engine speeds. Weak magnets or worn main bearing thrust surfaces will reduce output, requiring higher cranking speeds to start the engine. Coils need to be in good condition AND properly adjusted for easing starting and good performance, and the timer must be in good condition. The original type roller timers need to be cleaned occasionally, checked for wear, and they need to be lubricated with a light oil frequently. In my opinion, Marvel Mystery Oil is an excellent lubricant for roller timers.

I put a cup of Marvel Mystery Oil in my transmission years ago, on someone's recommendation.

That made the brake so slick that I could not stop for miles.

Ford listed info on the magneto, this chart was on the forum years ago, may not be entirely accurate as info is from the T days and measures were likewise approximate.
