What I see doesn't make sense. It seems the deep cycles do nothing. Can I get some suggestions for troubleshooting this? Thanks. Tom McCloud
You have an open circuit. Trace the wire from the deep cycles. Voltmeter or test light is fine. Disconnect from the truck chassis battery. At some point you will find voltage on one side of a point and zero on the other side. Repair, replace, reset, adjust, clean or tighten that place you find. Probably not mid wire but at some connection, fuse, circuit breaker or switch.
