TROUBLESHOOTING – POWER UNIT
Before attempting to troubleshoot the Power Unit, make sure an
adequate power source is available. The unit batteries should be fully
charged or the unit should be plugged into to A/C service with batteries
installed. Do not attempt to troubleshoot the Power Unit without
assuring a full 12V DC charge
The following tests require only a DC voltmeter (or DC test light) and a
jumper lead.
Step 1 - Attach voltmeter (or test light) leads to the negative and positive
switch terminals on back of wall switch (See Fig. 9). Does the meter
indicate 12V DC?
If YES, see Step 2; if NO see Step 3.
Step 2 - If YES, at the motor, check the incoming leads to 12V DC (if
necessary, disconnect leads at wire splices). Does meter indicate 12V
DC? If YES, Power Unit needs to be replaced. The motor is not field
serviceable. DO NOT ATTEMPT TO REPAIR. If NO, Inspect all wires
and connections between the wall switch and the motor. Repair
connections as necessary. Recheck as in Step 1.
Step 3 - If NO, Inspect all connections between battery and switch.
Inspect 50A Auto-reset Circuit Breaker (See Fig. 9).
Recheck as above in Step 1.
TROUBLESHOOTING - ELECTRICAL
Since there are no field serviceable parts in the motor of the Power Unit,
electrical troubleshooting and service is limited to replacing only those
components as previously outlined.
Thorough inspection of wiring and connections is the only other electrical
service that can be performed.
