A short exists between the
motor power connection
and the common connection
or ground (frame). Determine if the short exists between a motor power connection
and a common connection or between a motor power
connection and ground (frame):
1. Disconnect and isolate one (1) end of the common bonding
jumper located in the 180 deg. section that contains the
control panel electrical interconnect.
2. Use a multimeter to measure the resistance between the
motor power connection and the common connection. If the
value displayed on the multimeter screen is OL, the short
exists between the motor power connection and ground
(frame). If the value displayed on the multimeter screen is
<5
Ω , the short exists between the motor power connection
and the common connection.
