David.......REMEMBER, the 1-wire alternator requires goosing the cold engine to about 1800rpms (3/4-throttle) before it starts charging. After internally turning on, it will charge at 600rpms like the 3-wire. It's MODIFIED internal voltage regulator semi-keeps the VOLTAGE to about 14.7-volts (can go as high as 17v? without regulation) 14.7v will keep yer 12-volt battery nicely charged but should NOT boil the battery. Its a DIFFERENT regulator scheme than the 3-wire feedback scheme.
Ah resistors.....mysterious devices that bedevil novice shadetree mechanics. BEFORE yer conversion to EI, the previous converter used the cheap'n'dirty scheme of using the original 6-volt roundcan coil AND a 12-to-6v converting resistor. Since you used the recommended EI 12v "Flamethrower coil" which is designed to NOT use a resistor as required for the original 6v coil. THEREFORE, you DO NOT NEED enny resistor with yer 12v FlameThrower coil. UNDERSTAND???
I sure wish Pertronix would re-write their AWFUL instruction sheet.
Realize, with the "FlameThrower" coil, you will have HOTTER sparkies (more kilovolts) and you need GOOD silicon soft and flexible copper-core sparkie wire. ($15, cheap) Do not use modern anti-radiostatic carbon-string sparkie wire.
Yers is one of the SUCCESSFUL 12v Electronic Conversions ...because... its the 5-nipple sidemount which has ROOM for the EI module. Congratulations. .......Dell, yer self-appointed sparkie-meister and 12v advocate for the right reasons
