clintonnut 126 #1 Posted June 1, 2010 Is it okay just to switch the cables so it is a negative ground? My 876 for some reason has positive ground? Will it mess with the voltage regulator? Charlie Share this post Link to post Share on other sites
pfrederi 17,743 #2 Posted June 1, 2010 If your engine is spec 30108d you will also need to reverse the wires on your coil. For a positive ground system the wire from the ignition switch goes to the - terminal on the coil ...the + terminal goes to the points. For negative ground switch wire to + and - to the points. Not sure about your regulator...mechanical regulators are specific for positive ground....don't know about the solid state stuff Share this post Link to post Share on other sites

Fiddlestix 0 #4 Posted June 4, 2010 Will it mess with the voltage regulator? When I first read this I immediately thought: "Of course! The Delco Remy controller is toast!" I thought about it for a while since my elderly father commonly reversed the battery on his two positive ground Fords (9N and 600). Always unpon the replacement of the battery. I recall that several times we didn't need to do anything. I pulled out an old (1962) Delco Remy training manual and it did not directly say so, but in several diagrams for testing, I states "positive or negative ground". Implying the controller does not care about polarity. How did yours work out? :D Share this post Link to post Share on other sites
clintonnut 126 #5 Posted June 4, 2010 The regulator works and it charges. I guess I'll just switch the wires around and keep peace of mind. I hooked up headlights on it today with no problem. Thanks for the advice Charlie Share this post Link to post Share on other sites
