I was in a hurry making a new battery cable and reversed the the positive and negative wires needless to say the camera wouldn't start. I switched them back but still no luck. I opened up the TCS TXM-9 crystal controller hoping to replace a fuse but I didn't see one. Does anyone know if there is a fuse that can be replace somewhere in the camera, or have any other ideas on how to fix it. Thanks for your help.
