I agree, Jim. I grew up in Lake Wales, Florida and folks used to say, "If it rains in Tampa, a MOPAR won't start, here!"
I worked in a garage and my boss loved MOPARS. He didn't want to hear that crap about 'em not starting. He'd remove the original, cotton-covered insulated wires, switch to Packard 440 wires with rubber boots and his MOPARS always seemed to start great.
Contrary to the experiences above, we installed a lot of 8 volt batteries, in 6 v cars, trucks, grove tractors, set the regulators for about 8.9-9.1 volts and I don't remember rashes of electrical failures, (except for light bulbs)
