The "Whack-A-Mole" continues...
I now have the controller 12V wiring (I'm calling it C12V) and the auxiliary 12V battery wiring (call it B12V) totally separated. In addition I have the B12V system totally shut off - the 12V battery negative terminal is totally disconnected from everything and the positive terminal is switched off at the relay. Below is a sketch of the wiring. The main 4awg positive wires are now identical lengths and the 4 awg ground wires are now identical lengths. In this configuration the motors run. HOWEVER, the trike now pulls hard to the RIGHT on acceleration (this is opposite of the previous situation) and it pulls right consistently.
A little addition explanation of the wiring:
C/P is controller passenger side
C/D is controller driver side
The C12V is connected from ONE controller (the passenger side) to a fuse and then to five switches on the dash. These switches each have an LED indicator light and each switch has a ground pin to allow the LED to come on when the switch is on. Four of the switches feed power to the coil side of four relays. These four switches are all in the off position. The fifth switch is the forward/reverse switch. This switch feeds C12V power to pin 12 on the two controllers for forward and pin 14 on the two controllers for reverse. This switch also has an LED indicator light which has a ground pin. This switch must be in either the forward or reverse position for the motors to turn. The ground pins for all five switches are connected to a small buss and the buss, at present, is wired to the shunt. The B12V ground buss shown in the sketch is NOT connected to the shunt or to either of the main controller ground wires and the 12V battery is not connected to the buss.
Highly frustrating. I seem to be back where I started, just pulling in the opposite direction.
