Hello all,
My '67 1600 (U-20 and 5 speed) has been modified by the previous owner to
relocate the battery to the trunk. The positive cable is 1 or 2 gage to the
starter and the battery is grounded via a bolt through the trunk floor to the
passenger side rear frame member. The starter mount bolt is then grounded to
the frame near the engine compartment. Before the alternator failed I was
getting 13.2 volts across the battery terminals at 2000 rpm and only .1 amps
output from the alternator. Off the car, the alternator tested good at 30
amps or so at about the same voltage. I suspect that this set up does not
properly ground the battery/charging circuit and am considering installing a
4 gage cable from the battery to the starter mount bolt. Is this reasonable?
Recently, the alternator is only showing battery voltage (12 volts) when
running at 2000 rpm at the "Batt" terminal., and I haven't yet tested it off
the car. Could the poor ground be responsible for failure of the alternator?
Should I try to locate the battery back to the engine compartment?
