Any Issues with Jump Start of Positive Earth LBC

Hey guys

My new 65 Herald is Positive Ground. I jumped it with my Suburban and then thought "hey, I wonder if this might be a stupid thing to do...?" Any issues with jump starting a positive ground car with a negative ground car?

When I was in Jr. High, I borrowed the family Mercury Wagon (390 CI) and learned how to remove the battery and clean and reinstall. I put it in backwards and then learned how to replace alternator diodes. Don't want to repeat that performance 40 years later...

No issues as long as you connected positive on one battery to positive on the other battery and negative to negative.

Just make sure that the two vehicles are not touching each other. :eeek:

Just askin' - wouldn't you connect ground to ground and hot to hot? Ie - opposite of above?

Luke,

No! You definitely want to observe battery polarity. Batteries don't care which end is grounded.

Only if you crave excitement !
:devilgrin:

Seriously, there is a potential for fire and/or explosion if you connect the batteries backwards. As several people have said above, observe the <span style="font-weight: bold"><span style="font-style: italic">battery</span></span> polarity and ignore which terminal just happens to be connected to the car body (aka ground, which of course isn't ground at all).

It's been a long time since I jumped a positve earth car. Thanks for the heads up. Good to know. (not that these cars ever get flat batteries, right?)
