We've had the trailer three years now, but this weekend is the first time we've taken it offroad and camped away from any hookups. I'd only used the Shurflo pump when winterizing, never needed it hooked up to KOA water. Now in our third day offgrid, and I have a question.
The pump will run just fine, for a minute or so. Or all day, maybe, if we just use it sporadically. But from time to time it just stops. First time it happened I grabbed the voltmeter and checked at the converter and had power and a good fuse there. When I plugged the fuse back in, ( the 20 amp on the converter) the pump started up. I thought it must be corrosion or loose fuse contact, although it looked clean. Pump ran fine through some light, intermittent use. Then stopped again. I tried reseating fuse, no joy. Still had voltage there. So I opened cabinet and checked power at the other fuse, the one right at the pump itself. I pulled the fuse out to check it, it was okay and there was power to it. Now I'm getting confused. Plugging the fuse back in, the pump came on. Briefly. Now I've determined that simply turning the pump switch on the monitor off, and then back on, or turning the monitor itself off and on, will let the pump run briefly. Does this sound familiar to anyone? Turning power off and then after a minute, back on and the pump will run for a short time?
