So I'm currently attempting to repair the wiring in my 69 A108. I have ordered the factory repair manual from a reputable company but I am highly impatient and my ADHD has me chasing wires like a cat chases a mouse. I've got the key ignition, starter and starter solenoid all repaired and replaced with new parts. I've also replaced the cap and rotor, points and ignition coil. I am not getting any spark at my plugs. I am probably missing something simple but currently I'm lost and the schematics I pull from Google are worthless at best. Can I run a pig tail from the battery to the coil to catch the voltage or is there some way to get a spark without waiting for USPS to finally deliver my repair guide. Thanks in advance, peace and much love to my Van Outlaw brothers

With a jumper wire, just connect battery positive to coil positive, coil negative to distributor, and crank the engine. If the points are clean and set correctly, and you have a good, correct condenser, you should have spark from the coil secondary tower. Do no leave the jumper to the coil connected when the engine isn't turning, or the points may weld if they are closed with the engine stopped. Chrysler used a ballast resistor in the ignition primary circuit to limit current to the coil at low engine speeds. This resistor is by-passed by a connection on the starter solenoid while the engine is cranking to provide a hotter spark when starting, so check for good connections at the resistor (check to make sure the resistor hasn't failed) and starter solenoid. I have a reprint of the '70 manual, and it's schematic isn't much help.

The ballast resistor should cut down the voltage to 6 volts at the positive terminal of the coil,,,,,if you got or put juice to that terminal, then take a test light, hook it to ground and test the negative side of the coil while cranking the engine,,,,,the test light will blink if the points,condenser and breaker plate ground are doing their job,,,,,

Question: from my ignition coil, does the positive or negative lead go to the distributor?

Here's what I've done. I copied the pages from the manual and color coded the lines with marker to help me find each end a little faster. I'm not done with it yet.

I am using the exact same diagram. I bet you are the guy who scanned and posted it somewhere. Thanks buddy, that's the only schematic I've found that's accurate
