6volt positive ground swap to negitive ground?
I'm Considering swapping from positive ground to negative ground. I plan in the future to swap to 12v as well. What all leads must be swapped. The car is a 52 dodge so obviously the full current ammeter must be changed, the coil, but what about lighting horns, blowers etc. Do relays care which way there grounded? Is this something I should even worry about before the 12 Volt conversion? I want to get the car running and driving the 12v conversion will be done next winter when I blow it apart for bodywork and paint. It has stock engine really stock everything. Thanks for your help.
