What coil do you have MSD 8203 ,
calls for a .8 OHM resister MDS coils 5 6 7.
If you put a 1.5 in stead of .7 plus wire 1.4 ohm that is the same as 2.9 total
if you had 2 amps that's about 6 volt only 6 left for coil.
more resistance is less amp.
so 2 amp .8= 1.6 leaving10 volt at coil
so 4amps.8=3.2 leaving 8.8 at coil.
(AS I said lose the wire ohms) and use what they said .8ohms/.7ohms.
Ask msd if its ok to use a wire resister with there .7ohm resister. that's a total of 2.2 at 2 amps thaths 4.4 = 7.6 ,4 amps is 8.8 leaving 3.2 volts at coil.
