Troubleshooting raymarine power issues - 2010 3600 Open

[coyler]

Hi everyone-

2010 3600 Open.  

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.

Are you sure you checked ALL The breakers?

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.

Thanks for the help. User error strikes again.

It happens to all of us, glad you found it, Happy Boating
