49 Packard polarity change

Posted by Wolfstalker On 2015/7/15 16:54:26

I recently purchased a 1949 Club Sedan with the 288. I noticed that the battery was negative grounded and after reading what I found posted here I decided to reverse it. I pulled and rotated the battery and reconnected it and it started immediately, and the ammeter seemed to be reading correctly. I next took a jumper and gave a quick touch to the BAT terminal on the regulator and the ARM terminal, got a spark and instantly removed it. Unfortunately I forgot and did this while the motor was running. The engine stopped and now I can't get it restarted. Did I damage the regulator? Another possible problem is that this one has an electric fuel pump - will it work with positive ground? When I turn the key I hear it start to humm, but perhaps it is going in reverse?

Can anyone suggest what I might try now? Thank you.
