Blown water pump fuse November 21, 2013, 01:55:43 am Yahoo Message Number: 143738Hi folks, a small electrical issue to ask about. We have a 2004 LD Rear Bath.Camping at Morro State RV park near Laguna Beach. All electric working well. Plugged in to electric here. Today we had water pump switch on and switch light went out. Checked wp 10 amp fuse and it had blown. Replaced with a new 10 amp fuse and 30 minutes later it blew again. I didn't even use or turn on the water when it blew again. Any ideas or thoughts appreciated. Greg with no water pump.
