Hello,
I experienced something new at the end of last season. We went to a Marina, planning to stay overnight. This marina was recently updated to the latest in "show power" stuff... (not really sure what that means). Anyway the Marina staff came out and wanted to test our boat before allowing us to plug into the Shore Power. They wheeled a cart over, and explained that this cart would be plugged in-line with the show power and my boat. Basically they said it would test if the boat was leaking any current into the water. Ok seemed to make sense. Anyway to make a long story short, my boat failed miserably and we weren't able to plug in. They said we were leaking over 200mA into the water. Our boat's a 1992 SeaRay 330 Sundancer, Twin 7.4, AC, and Kohler 5K Genset.
Has anyone else experienced this new type of Marina System, and know how to diagnose this type of failure?
The exact process they followed is outlined below:
- Asked us to turn off all breakers on the boat, both main and individual breakers.
- Brought cart over, and plugged it in-line with the #1 outlet (Not the AC one) on our shore power, we were using our shore power cable.
- Asked us to then turn on the main breaker, we did so, and the tester immediately tripped. Hmm ok that's not good.
- Then we tried the AC outlet. Same result immediately tripped the testing machine when the main breaker was switched on.
- When then tried my backup shore power cord. Same results...
Any help diagnosing this would be greatly appreciated.
