Hello everyone. I'm trying to convert over from positive ground to negative ground. Still keeping it 6 volts. I've read this great article from Fifth Avenue Garage and was wondering if its all I have to do. Any help with changing over or the steps it takes would be helpful. https://fifthaveinternetgarage.blogspot.com/2017/06/changing-your-electrical-system-from.html

I've recently converted the clock to quartz, but the clock guy cant seem to get it right. The clock keeps grounding out to the case when mounted to the dash. Is there anything I can pass along to the clock guy he should know. Thank you. This is going in a P-15 6 volt Pos Ground.

Hi everyone, I am new to the 6 V positive ground system. So I apologize ahead of time for me seem like trivial questions. I have a 1948 dodge D 24 sedan with the 230 flat head six. She runs great at idle and all the way up to about 2000 RPM. Past that she start sputtering and Backfiring. I have rebuilt the carburetor, installed new points, condenser, rotor, distributor cap and set the timing. She honestly runs great at the lower RPMs. Once I start to accelerate or rev the engine from rest and get to about 2000 RPMs she starts to backfire and sputter. I have monitored the spark through my timing light And found that it starts to go erratic. I monitor the voltage on the positive side of the coil And at idle I have about 2.4 v. As the rpms raise the voltage drops and I find that the missing starts once the voltage hits zero and goes negative. Not sure what this means. I also used a test light to monitor the pulsing of the signal. The signal continues to grow brighter as the rpm is raised until I hit that certain mark. Then the pulsing is very erratic. It almost is acting like a rev limiter. But I cannot find one anywhere and my service manual makes no mention of it. I also must mention that monitored the vacuum with a gauge at the intake and have 20 inches at idle. If anyone has any helpful ideas I would love to here them. Thanks
