I know what your getting at, and do know how to do that...
but was prefering it to be SLA (sealed Lead Acid)
If motorbike batterys are sealed.. then sorry about this mistake.
and I wasn't sure if SLA could be charged by just throwing a higher
voltage across the terminals. (I know nothing about charging batteries)
I have had the thourght of re-running the wire to something a bit
thicker, it runs 3 meters, 2 wires, 1 Gnd and one Pwr.
I was thinking of running both wires as Positive, and just using the
body of the vehicle for Gnd (negative)
What ya reckon?
Thanks for the replies...
