No spark.   Bought this car some time ago, delivered on trailer by seller. New 6v battery was DOA. Seller then hooked up 12v battery to get it started. Very hard to start, and ran very rough with a lot of throttle. He got car up driveway, but couldn't understand why car ran so rough, so hard to start. 12v battery started to smoke. He forgot car was positive ground! Hooked up battery correct way, then started very easily, and ran smooth. Not able to start car since. 6v battery was charged, engine cranks, has gas, but no spark to plugs. Replaced condenser and coil. Still no go. What to do ?

No spark.   You have power to the coil with the ignition on?

No spark.   Strange. I used a multimeter to test voltage at the coil's positive terminal (i believe), and got 6v with the ignition OFF, then drops to zero when ignition switch is turned ON ! Exactly opposite of what I would expect. MadPlowMan New User Apr 16, 2012, 4:23 PM Post #4 of 5 (3883 views)      Re: 1948 Dodge Custom won't start. No spark.   On the coil you have two small wires one goes directly to the distributor , the other is to the ignition switch. To test this out with the weird problem of no voltage when the switch is on. I would disconnect the ignition wire from the coil. Not the one going directly to the distributor. Then if positive ground as you say run a jumper wire from negative battery terminal to the coil terminal that you took the wire off. Now you have bypassed everything, if you still don't get spark its in the distributor. If its getting spark, it proves the problem is in the harness or ignition switc In Reply To zmame Veteran / Moderator Apr 19, 2012, 8:03 PM Post #5 of 5 (3842 views)      Re: 1948 Dodge Custom won't start.
