ECN Forum Forums General Topics of the Trade General Discussion Area Brother-in-law has a leak...

Something doesn't sound right here,
Where exactly in the system is the 97V he is measuring?
If it's at the supply end of the cable, I'd suspect a faulty contactor or the like.
What controls this pump?, if it's got a pressure switch on it I'd make sure that the pressure switch has been wired correctly.
Failing that, the pump unit should be pulled up and checked, it may have something jammed in the impeller.
I would suggest that the cable be meggered between all cores and a continuity test done on each core before pulling the cable run out.
What I usually do before installing any cable is megger and continuity test the drum of cable before installation and then test the cable again after installation.
It's not unusual to get a bad reel of cable from the factory.
