I'm in the process of wiring, and I'm a lot confused.
Is that diode for the contractor required? I thought I had all the parts needed, but in another wiring diagram I was referencing before this one, there was no diode.
Also, I have the SW200 contractor as seen here:
If you notice, there's 4 sets of terminal connections. Following the diagram, it doesn't specify which ones to connect everything to (pre-charge resistor, batteries, controller). I'm mostly a mechanical person, so this is a new area for me to explore. I've never wired anything or worked much with electronics.
