However, I dont see how that fuse blew. Seems that there was a dead short between the 2 batteries. As if one was reversed polarity. Is the control ground the only circuit on the ACR, you are using? Thats one of the small blade terminals along the bottom. Or are you using the SI?
The ACR is connected to the small ground, going to a bussbar. I also have the LED going to the accessory side on the switch.. maybe i should change that to the house? Not that it is causing the issue.

I do have a question in regards to the bussbar. I connected the ground from the engine to the bussbar, along with the negative battery terminals to the bussbar. Do you think it's wise to have the engine ground go to the bussbar or should it go directly to the negative battery terminal instead?
