Well, I have everything connected and running with the rear wheels off the ground. It was very satisfying to see it actually run after all this time. Electrical troubleshooting has been an interesting experience. First, the electric motors had their encoders wired incorrectly at the factory, causing the motors to go into ‘limp’ mode, about 20 rpm. Brian at HPEVs walked me through the procedure for connecting the encoder correctly. Next, the primary motor didn’t recognize the secondary one, so now I was able to get full rpm but only half power. Again, Brian walked me through troubleshooting steps for CANBus wiring and I found the baud rate on the secondary motor to be half that of the primary one. Changing the value was simple and I finally had full power and speed!
Next, my BMS wiring was done incorrectly on the last battery in each of my two battery packs. I hadn’t terminated the wires the way Dilithium Designs instructed me to. Oops. Fixing that was a pain because I needed to partially disassemble the rear battery pack to access the wiring. I finished that a few days ago and yesterday I spent tidying up all the wire runs. The truck has all new 12volt wiring including a fuse panel for the first time in its life.
I hope to have it all back together for the 4th. I’m thinking of entering our local parade as the “green berets”...
