Has anyone hooked up two 12 volt batteries in parallel? Is your negative wire hooked to the same battery as positive lead or the other battery? Since adding the second battery my frig throws a low voltage error intermittently. Any suggestions - please advise ----Thanks
If you Google hooking up,two batteries it shows the negative lead on the second battery when in parellle
When hooking up in parallel, ALWAYS connect positive to positive and negative to negative.
