Has anyone had problems with Carling (blower) switches, specifically model 0720R? It looks like this (not pic of my switch).
We were out last trip and the bilge blower stopped working, not something you want happening on an I/O boat... Turns out the contacts of the Carlingswitch 0720R were all carboned up and pitted, it was reading 40 ohms with a meter. I know things can go bad, but this seems a bit ridiculous as the Detmar blower only draws 3.5 amps and I would think the switch would be rated for at least 10 amps.
I guess I could have got some water in the switch while cleaning the boat and since the contacts sit at the bottom of the switch, any water would have gone there. Though, I would also think the switch should be waterproof/resistant.
I'm popping this one back in, but need to get another switch, probably going to get something other than the Carling.
