Low Voltage Test Works, Hose Doesn't
Frustrated Bob, Kansas City. Beam Model 190, circa 1984, would not run even when using manual switch. Because of much arcing, age of Lamb 115334 motor, I replaced it. New motor runs great but power unit won't start using on/off switch on hose. Checked all 4 outlets for broken wires, found none. Unit comes on when 24v terminals are shorted. To test hose, switch, relay, etc., I used a spare wall outlet, plugged hose into it, then inserted wires from the outlet directly into 24v terminals on power unit. The switch turned the power unit on just like it should. I am 110% sure I do not have any rodents, e.g. rats, chewing on wires inside the house. But now I don't know what else to test and surely can't rewire an entire 2 story house. Have any other ideas?
