TLDR; Brand new GX CS4-i bought on Amazon, water pump did not function even after the usual trouble shooting. Water pump motor measured 17.2-17.3 M Ohm. Board produces 0.0 Volts on the pin outs. Contacted Amazon CS and contacted ANKUL.
Long story long: Several years ago I knew I wanted to go down the PCP road. I also knew the actual expense of PCPs would be accessories like pumps, bottles, etc. So for years I had a hand pump while I built an arsenal of accessories, like SCBA bottles, as well as PCP guns I wanted. I pumped a 4.5L bottle to 3000 PSI with a hand pump - weeks of 20 rep sets at a shot to fill from zero PSI to 3000 PSI. When I got done I swore I had sweat earned myself an electrical pump. Years went by and I never pulled the trigger on a Yong Heng, though I had designed exactly how I'd lay it all out and what upgrades I'd do.
Fast forward to this year, the GX CS4-i caught my eye. Decent price, very little upgrading needed, can fill my 9L bottles. Received my pump, bought at Black Friday price, on Sunday. Set it up Monday, carefully cleaning out the water reservoir. Worked out the burping process of the water fill system. No water pump function. I did the poke it with a stick trick, ensured there was no air bubbles, etc.
Nothing worked to get the water pump running, so I unplugged the water pump from the board, measured the windings, 17.2 to 17.3 MegaOhms. Seems more than a little high, but what do I know? I checked the voltage on the output pins at the board - 0.0 Volts. Hmmm.
Called Amazon CS, got the seemingly requisite, difficult to understand representative, and filled out my request to ANKUL. We'll see what they want to do. If they want to send me a new board and pump I could install it, but I'd rather have a new pump since it arrived defective.
Anybody know what the correct winding resistance ought to be, and/or has anybody had a board failure of this type?
