Good morning Dean,

First of all sorry for your mishap, but congratulation for the maintenance you did on the generator! On my SM2K, cleaning well the raw water pump, eliminated the faster than expected destruction of the impellers: http://www.nikimat.com/onan_water_pump_cleaning.html Also you should look at what Perigee did, which is adding a filter which will catch the blade of the impeller. I was going to installed a “Y” Valve to catch the blades, but I think Perigee system is far better. Regarding the change over, yes it worked as expected (over riding the shore power), but I don’t know why it got stuck… I would try shutting down all 220 volt system to see if it switch back. I think it is the following on the SM2K, and I would suspect it is similar looking on the 54, but could be wrong: http://www.nikimat.com/galvanic_isolator_part_2.html 6th picture, the box on the left where the 7, 8, 9, 10th pictures where it says “Quai” and “Onduleur” Good luck and keep us posted of your finding. Sincerely, Alexandre --------------------------------------------

Subject: [Amel Yacht Owners] Shore power issue To: amelyachtowners@yahoogroups.com Date: Thursday, July 19, 2018, 6:41 AM Hi,Today’s job was to replace the impeller in my generator. It was shredded, so I opened up the heat exchanger to clean it too, it was gunged up badly, so after cleaning all that I had a look at the exhaust elbow too, and cleaned that out as well as the muffler. Great. Put everything back together, and started the genny to test. Generator worked fine but ... I forgot when starting the genny we were still running some things on shore power. The genny seemed to override shore power (as it should I believe), however, on shutting down the generator, the shore power no longer works.I’ve checked the dock supply and the stern breaker - both good. But I get no light on the 240v panel. I’m thinking the changeover switch has somehow stuck, but why, where is it, how to reset it ?Or have I smoked the changeover switch by firing up the genny while shore power is running?So many questions! Thoughts ? Many thanksDeanSY StellaAMEL 54 #154
