Having problems with your Pontiac Grand Prix ?
I want to use two 12V bateries to make a 24V start for my car...
You can connect 2 batteries to produce 24v connect one possitive terminal to one negative terminal. The other free terminals +ve and -ve will now have 24 volts when checked. Do this off the vehicle first so you familiarize yourself with the setup. \015\012Hope this helps...
