The past few days were spent building the rear electronics and battery jumpers. I decided to use two PVC J-Boxes to house the pair of HV contactors & control board. The second J-Box will house the regen-diode, 60 amp DC fuse and a cooling fan operated by the control board.
Here is the first box.
The second box is not complete yet, I still have to install the fuse holder and diode on its heat sink.
Now, copper terminal lugs for #8 wire are not cheap. I went to Home Depot Sunday to get 40 of them and decided a dollar each for copper bolt type was a bit too much. The crimp version was even more expensive at over $1.50 each. I opted to make my own.
I used #8 THHN stranded wire and 1/4″ soft copper tubing. I cut the tubing into 3/4″ pieces and slide them onto the skinned ends of the wire after applying a liberal coat of rosin flux. I then used vise-grips to flatten the tubing onto the wire.
I then used a big soldering gun to flow solder into the crimp.
I used a hand drill to drill a small 1/8″ pilot hole in the center of the new terminal. Next I clamped it in a drill vise and drilled it out to 3/16″ to fit the battery terminal bolt.
The finished jumper after a bit of touch-up on the grinder and wire brush.
These bolt up nice and cost a lot less.
