These are my log notes on the problem:
Monday 13 February 2012
Called ShurFlo 800-854-3218 ex. 6785
Spoke with Pedro, he said bring old pump to him at:
5900 Katella Ave
Cypress, CA 90603
And he will swap for replacement pump, no charges; just bring some paperwork as to this being a new coach.
Hours are Mon-Fri 7:00-3:30 local time
Smart Sensor 5900-0201 is no longer available
Replacement is Revolution 4008-101-A65 or e65
Removed pump and went to see Pedro in Cypress on Tuesday 14 February 2012. Swapped pump for the 4008 model and installed it in the coach, all seems to work well.
Well, IMHO you got lucky as they go by the manufacture date stamped on the pump which I'll bet is long past (even though your coach is new; maybe FR would have helped out).
The replacement Revolution pump you mention is a lot "lighter" as far as I can see. BUT, a LOT cheaper too!!!
I figured I had nothing to lose so I seriously dug into the pump. There is in fact an electronic "module" in there that the power goes through. I also checked the motor for a frozen bearing; shaft turned as smooth as I've ever seen anything turn.
SO, being sly, I decided to connect the 13V supply wires directly to the pump motor leaving everything else out of the loop. Had good 13.2 volts, but the motor would not spin up. And yes, the 13 was really there; checked with a multi-meter.
Now I'm thinking that maybe a winding in the motor may have an open, or other similar problem. Too late for today, as DW is making din-din. But tomorrow AM I'm going to disassemble the motor itself and see if I can find anything.
Am I having fun yet?? NO!!! I'm pretty good at mechanical and electric things, but HATE to work on that stuff.
