Apr 262012

After a machine move we got asked to look at a webster bennett control panel and main motor, the motor had been making a horrible noise and not running poroperly. After an hour it was diagnosed that the A1 and A2 had been reversed on the wires going to the motor and this had caused one of the motor hrc fuses to blow. Three new fuses and correctly wired and the unit ran fine. The control panel was integral to the machine and built by Square D in 1964.
