Electronic Ignition Question

[white halftrack]

I have an electronic conversion on an tractor that I would like to
switch over to a runner. I do now know much about them and
would like to have some idea of what I am doing before I go out and
fry myself up some electronics.

The facts.
EI tractor runs really well.
Is 12 volt.
There is a resistor mounted right by the coil.

I presume.
The reisistor means that the coil is 6volt.
I can just switch resistor forward to the receiving tractor as it was
12 volt also, but points.

From what I gleaned in the archives, if I get a different 12 volt coil, I
would not need the resistor? I could not understand that as I
thought that would still give too much volts or ohms or jules or
stuff to the EI distributor and fry it.

Thanks again.

Agree.

The silicon device that dumps the storage capacitor to initiate
the spark can only handle so much current and heat is a
consideration. Not really a big deal when you think about
regular ignition points.......installing a current limiting resistance.

My MF manual says that regular mechanical ignition points are
rated for 5 amps max which, when you do as Mr. JMOR said will
put you right there....14.5v alternator/generator output at PTO
rpm divided by 5 amperes is right at 3 ohms of series resistance
required.
