For the first time in 3 years, I can not get navigation electronics (Raymarine e140W + ST70s) to power-up. DC switch panel does not have a switch for the electronics. Same with helm circuit breaker - no breakers there.
Does anyone have an idea where to start troubleshooting? Presumably there are a set of fuses behind the helm but not sure if that's where I should start. Thanks for the help.
Start at the power cable behind the unit and work backwards from there. If everything else is working, it's not going to be a major issue. Probably an inline fuse or where the power cable connects to the bus bar.
Closing this out. Donald was spot on. One missed panel switch which I found after hours with the voltmeter in tight quarters. Now I fully understand the wiring and location of the inline fuses.
