I have a recently added M715, but its been modded with several things that I am trying to decypher...and the previous owner was not the builder.
One is it has a 69 pontiac 400 V8 in it, and what looks like an alternator on it, but only one cable leaving it, with a vacant plug-in spot that has two terminals in it. I see the wiring diagram shows that , but in all of my by-gone days of muscle cars, mopar, the alternator had a multi-wire plug on it. My curiosity is further complicated by what seems to be a mid-point tap of the crossover cable connecting the two batteries. It also seems that the positive cable coming from the front battery only goes to the starter.
SO, here are my questions...in the dash are some newer Sunto gauges...is it possible the 2nd previous owner found a 24volt starter that fit that engine and rewired the motor and the cab electrical system to be 12 volts?
Thanks
