More ignition issues on the dart

Additional test.........

1...You want to find out if the box is GROUNDED (it MUST be) and if the coil is drawing current. Turn key to "run." Measure coil + to ground. You should have 6--10V or so. If you have "full battery" it means box is not grounded, or coil is open, or something wrong with box

2...Turn key to run. "Rig" a test gap at coil tower. Disconnect distributor pickup and tak the firewall harness end, NOT the distributor end. Repeatedly tap the bare terminal of the connector to ground. You should get a hot single "snap" spark each time

Test for spark with a test gap rigged up at coil tower WHILE CRANKING. Try it using the key to crank, and try it with key in "run" and jumper the starter relay to crank.

To get some idea if the dist. pickup is good, hold your meter probes in the dist. connector and spin the distributor or crank engine. You want your meter on low AC (not DC!!) volts. It should produce about 1V AC

Repeatedly work all ignition system connectors in/ out several times to 'scrub' them clean and fell for tightness The ignition box, the ballast, and ESPECIALLY the distributor connector.

Examine the pickup/ reluctor, look for rust, strike damage, shaft wobble or play, etc.

Pickup coil should show continuity between the two connector pins and OPEN (infinity) to ground.
