I'm thinking about making a pigtail to supply the control unit with an external 12v source since I suspect a problem between the panel and the controller. This is to determine whether or not the controller is working.

I plan to fabricate a pigtail with a 10a inline fuse for protection, but the wires supplying the controller are very small and the manual says that the controller uses up to 7.5 amps.

Does anyone see a potential issue with this troubleshooting idea?
