Working from battery to lights the following could be the issue if your use/store isn’t:
1) discharged house battery
2) 50amp breaker in battery compartment could be tripped
3) use/store switch faulty
4) latching relay faulty
5) reverse polarity fuses in distribution center blown
These are the lumps in the line for 12vdc power.
If you toggle the use/store switch and hear the latching relay then look at 5. If not then look at 1 and 2. This should help you narrow the problem down. Good old Navy troubleshooting. ;-)
