Thread: HEI ignition for a 283

Tweet

Here, try this picture. It should give you a basic idea of what your trying to do. Check the wire that goes to the positive side of your coil, (disconnect it first) with the ignition switch in the run position, see if it has 12 volts on it. If it does your all set! That will be the 12 volt input into the HEI distributor. If it doesn't, follow it back to the ignition switch, measure voltage at the switch. It "should have" 12 volts ( or battery voltage) at the switch. If you have 12 volts (or battery voltage) at the switch but not at the coil, there is either a ballast resistor in the circuit or the wire itself is resistor wire.

If you have a known resistor, bypass it (simply connect together the 2 wires you remove from the ballast resistor) If the wire itself is the resistor, then simply run a new piece of wire from the switch to the new distributor.

Maybe this will help or you can simply ignore me...
