I have a failed hand controller interface (HCI) on my Mastiff. It was installed by a previous owner and I do not have any documentation on the system. I believe my HCI unit is bad and I cannot find a place to purchase a replacement. I know the purpose of the HCI but I have no wiring diagrams to verify that it really is the HCI that has failed. Furthermore if I did have a good wiring diagram I could build my own replacement HCI. Any ideas on where to get the HCI or wiring diagrams? Thanks
