electronic ignition swap on a 64 Valiant..........CANT GET TO RUN.....HELP
If I use any of the factory wires, I can't get any fire.I have All the factory wires unhooked, it's the only way I can get any fire. I've hooked plenty of these up over the years, but on later models, like 1971. I would be nice if you were near by, I had anot her certified Mopar mechanic today come to look at it when I talk to him on the phone and told him what it was doing he told me over the phone he knew exactly what it was after he got here and I showed him what it was doing he told me he's never seen anything like it before
It's certainly difficult to know what you might have done. The "one big thing" that gets a lot of people is the ballast connections, "let's go back" to factory. Refer to your shop manual.
One side of the ballast gets power from the key "in run" and also branches off to feed the voltage regulator
The other side of the ballast goes to coil + and also "receives" the brown wire coming out of the bulkhead which is the bypass circuit.
The "run" side GOES COLD during cranking. The ONLY ignition power source in cranking is the BROWN which electrically goes to coil +
On your electronic box, this brown (during cranking) feeds BACKWARDS through the coil resistor, and out to the box, thus powering the box during cranking.
CHECK your voltages
With key "in run" you should have:
1....Same as battery on "key" side of ballast, IE 12.6 or whatever
2....Something from 7--10 volts on the coil+ side of the ballast.
3....Coil NEG should be quite low, 1 or 2 volts.
++++++++++++++++++++++++++++++++++++++
Voltages in "crank" (starting)
Coil plus should be very close to same as battery, IE if battery pulls down to 11V in crank, the coil + should be very close to this
The "key" side of the ballast in "crank" will be LOWER, perhaps 10V.
These systems "generally" have troubles with distributor reluctor gap so check that, and "work" the distributor connector in / out several times to scrub terminals clean and check for "tightness." There is a tiny bit of current in the distributor pickup, they are very prone to troubles.
