Hello, first post and first time working on an electric vehicle. I have some moderate motor controller experience from robotics, but nothing like this.
I purchased a Miles zx40St Electric Truck, I was under the impression that all it needed was new batteries, but upon further inspection that appears not to be the case. When I turn it on, I'm getting an error code 14, precharge failed. In searching through old forum entries, I found something about connecting a resister across the main contactor. I'm reluctant to attempt a fix without having a reasonable idea of what I'm trying to accomplish, plus I don't even know what the main contactor is. I'm reasonably smart and willing to do the research to understand what I am doing, but I'm pretty far out of my depth at the moment.
Can someone provide me with some information on what this error means, what is a precharge, what the main contactor is, and where I go from here? Pointing me to documentation or reading material is perfectly acceptable too. Currently I have the Controller manual and an Electrical Troubleshooting manual for the truck.
Thanks in Advance.
