fastwolff Posted October 9, 2009 Share Posted October 9, 2009 (edited) I have a 1960 H67LT with positive ground. I want to rewire the entire truck and switch to positive ground w/alternator. Would like a diagrahm that includes color code. color code not important!

Greg Rider Posted October 10, 2009 Share Posted October 10, 2009 If you are completly rewiring then dont worry about color unless you are going for a factory look. If you are doing a change over like I did and leaving stock wire and gauges in place then it is easy. Is you engine diesel or gas? That is a not a big issue but it wil help me walk you through it. I am finishing up a 1955 Dodge M152 ambulance right now and I am leaving the 24 volt starter and generator in place and doing everything else 12 volt.

Tony Ingram Posted October 16, 2009 Share Posted October 16, 2009 I said screw it and just converted my H-63 to 12 volt negative ground. I had too many problems with the series parallel switch. Got an alternator and started for a few hundred bucks. Now I can actually understand it.. I know Tom Gannaway has a wiring schematic on oldmacksrus.com if I remember right..
