I know it has been a while since my last post. I asked a question sometime ago about a problem one of my customers were having with a 3 hp 3 phase propane pump motor. Got alot of great ideas (thanks to you guys) we finally narrowed it down to a bad set of contactors (AFTER WE HAD REPLACED JUST ABOUT EVERYTHING ELSE!!!!) After overhauling motor, installing new fuses the only thing left were the contactor switch. After replacing it, all has been well. I suppose the contacts were pitted enough to allow current to pass through but would generate enough heat under load to kick out the heaters. Oh well when all else fails replace parts till it works again. LOL. I spent alot of time on this project that I did not bill the customer for for the simple reason that I felt like I was getting nowhere and he was spending a fortune repairing motors(which had been underwater and had ALOT of corrosion inside the connections box)replacing parts and fuses and still was not getting his customer satisfied. OH WELL it was a learning expierience for me. Just for future refrence is there a test for contactor switches.
Thanks again to everybody's input.
