reverse polarity with jumper cables
« on: March 13, 2010, 08:21:07 pm »
CRAP! reverse polarity with jumper cables on my 73 350 k20.  saw some smoke come from wires going to the firewall.  Will not crank, but fuel gauge and temp gauge read even with key off. Problem is i broke my right hand and i am limited in using a ohmeter, CRAP, any ideas where those wires are meeting at on firewall? thx
