Re: 49 Packard polarity change

Thanks for the speedy reply. I saw two wires on the fuel pump so I'll try and reverse those and see if that brings any joy. Otherwise, I suppose I'll need a new one - any suggestions on a brand or model number?

Same for the regulator - mine has one mounting screw at the top ear and three screw terminals in a row along the bottom ARM -FLD - BAT. Anyone know what make and model that is?

When I changed the polarity and then started the car it fired instantly, but just after I did the erroneous polarity touch at the reg it stopped running and will not restart, which leads me to believe that the reg is probably OK but the modern elec fuel pump may have been harmed.

That's what I get for not reading all the way through and seeing on a later post that the polarity things should be done with the engine off. Oh well...
