ignition help

Break points ignition is the simplest in the world.

1...You need voltage to the coil, obviously
2....You need a GOOD CONDENSER
3....The points must actually carry current, not just visually open and close

"How it works" THIS IS IMPORTANT I am not trying to talk down to you

There are two ways to crank the engine and start it with a "working" system...............

A......"Key in run" jumper the relay, crank and start
B......Crank the engine and start it using the key to crank

WHY? is this important?

Because Mopar has TWO distinct electrical circuits

1......"run" .......With the key in "run" the IGN1 terminal feeds power out through the bulkhead connector to the ballast and onwards to the coil. THIS IS HOT ONLY IN RUN, and not in "start."

2......"Bypass" With the key in "crank" or start, the bypass circuit is hot ONLY IN START, comes off a dedicated contact on the switch, runs through the bulkhead, and feeds power direct to the coil

So if there is a problem in the "run" circuit, and you try to check start by jumpering the relay, you will not have power

Conversely, if there is a problem with the bypass circuit, and you jumper the relay, you will not "see" the problem

THE FACT (if you are correct) that you do not have power to the coil (assuming you are cranking with the key) means there is a problem in the IGN2 circuit, normally brown wire, which connects to the COIL side of the ballast

ONWARDS............To double check, and make sure the ballast, run circuit, coil and distributor are OK, TRY starting the car "in run" while jumpering the start relay. The coil will get less voltage, and produce a weaker spark, but it likely will fire and might run

You need to go over to MyMopar if you have not, and download yourself a free service manual, as well as the aftermarket (simplified) wiring diagrams there
