New poster here. Trying to get a 1970 A65T sorted out. Wanted to order some LED bulbs for taillight and speedo - have a choice on either positive or negative ground system. Not sure - how can I verify this?
Check at the battery, if the + goes to frame it's positive gnd. OR Put your meter + lead on the battery + terminal then put the - lead onto the cylinder head, If it reads volts then it's negative gnd. if it's zero then it's positive gnd.
