She was getting juice - 12.33V/DC - so that wasn't an issue. But, when I'd hit the switch to turn it on, I'd get a draw-down on the electrical (e.g. lights dimming). So, I check the wiring - and it's getting juice (as I said). I removed the pump, opened up the pump, found the bottom red wire on the pump harness was shorting out from serious corrosion - kind of arc-welding itself and shorting out to the frame of pump. So, I ordered the recommended replacement [Jabsco 31395-0092 Marine ParMax 2.9 Water System Pump (2.9 GPM, 50-PSI, 12-Volt)]. The 4405-143 is rated @ 3.3GPM & the 31395-0093 is rated @ 2.9 GPM which is great. I looked at more expensive models, but I need to stay within a limited range since overpressure on the hot-water heater & other water fittings might not be conducive. So, life is good - I came, I saw & I found some work to do! Free shipping. Cost was $88.00 - not so bad.
