I recently acquired my grandfathers 1948 P15. It hasn't seen the road in over 15 years and has passed from my uncle to my cousin in the meantime. The engine was replaced by my grandfather many years ago with a P23 engine. I am in the process of getting it running again and need help with the grounding. Currently the battery appears to be wired as 6V negative ground instead of positive. The negative battery cable is terminated to the engine block. The ammeter deflects negative when lights and accessories are turned on which indicates at least this was rewired. The regulator is a VRP-4501A. I have no spark and am trying to eliminate possible causes. This was supposedly a running vehicle when it went to my cousins in 1997. Would they have converted to negative ground for a reason? Should I be concerned and switch back to positive ground? Where can I find a electrical diagram for this car? Thanks.

My 48 Dodge D-24 [ by the previous owner ] was converted to a 12 volt system, however, it was kept as a POSITIVE ground system. It has a 12V generator that is working fine. I am switching it to a NEGATIVE ground system tomorrow. Anything I am missing in the following steps: 1. Disconnect the battery 2. Reverse the wires on the coil 3. Reverse the wires on the ammeter 4. Reverse the battery cables. Thanks, Mike
