Re: Fiberglass radiator fan explosion! Reply #60 – November 27, 2012, 08:50:21 pm I burned up the diodes on my boost switch wiring after I installed the wrong boost solenoid. I put in one that was only rated for intermittent duty instead continuous duty. I forgot to check that little detail. After several days of being on, the coil finally overheated and shorted to to ground. It melted the diode and the several inches of wire on either side along with the second diode wiring. I could have started a fire and burned down the coach but I think it stopped there because it melted the solder and created an open circuit. When I rewired it, I installed a fuse going to the solenoid to prevent such a mishap again. The purpose of the diodes, if haven't figured it out, is so that the boost solenoid will get power from either battery bank regardless of which one may be depleted.I wish you the best of luck in getting your coach back on the road.

Re: Fiberglass radiator fan explosion! Reply #61 – November 27, 2012, 11:33:46 pm I cut both diodes off because they appeared to have melted in two. I installed disconnects on both of them instead. I have both wires disconnected currently. I will probably reconnect one of them after I figure out what's going on. If I ever need to I can swap batteries by connecting the other one... so I'll be my own diode I suppose... I don't think the solenoid is working currently anyway. I will have to test it and see.
