POWERBOARD® TROUBLESHOOTING
Problem: Boards do not operate
Possible Causes:
• Connected to incorrect vehicle wire
• Wire connections not secure
• Bad Battery Connection
• Fuse Burned
• Factory door-ajar circuit inoperable
Problem: Intermittent operation
Possible Causes:
• Wire connections not secure
• Bad battery connection
• Bad ground
Problem: Boards operate randomly
Possible Causes:
• Wire connections not secure
• Connected to incorrect vehicle wire
Problem: Board shakes and/or shudders during operation
Possible Causes:
• Bad ground
• Wire connections not secure
• Links misaligned
• Bad battery connection
Problem: Board squeaks or creaks during operation:
Possible Causes:
• Gear shaft wedge bolt is loose
• Loosen mounting bracket and board attachment screws.
Adjust linkages so they are parallel to each other and the moise is gone
Tighten all fasteners.
Problem: Board stays down all the time and can be moved by hand:
• Gear shaft wedge screw is missing or loose
Problem: One door operates the board and the other does not:
• Wire connections not secure
POWERBOARD® SERVICE TIPS
Adjusting Linkage Alignment:
The board is designed to stop travel when the system senses a load.
Misalignment can cause the board to stop early.
To adjust, loosen the boards from the linkages. Loosen the linkages
from the vehicle. Cycle the boards up and down a few times.
With the linkages extended, re-tighten the boards to the linkages.
Cycle the boards again then re-tighten the linkages to the vehicle.
ATTENTION: DO NOT REMOVE THE FASTENERS
Confirming PowerBoard® is functional - black controller:
To test the controller (#496.11), wire harness, motor, and lights
work, hook up to battery and touch any of the 4 door trigger wires
to ground. The board for that side should extend and the lights
should turn on. The board should retract and the lights go off
when the wire is removed from the ground.
Boards don’t operate correctly when connected to wires
identified in instructions:
Unfortunately, vehicle manufacturers do not consistently keep the
same wire colors in their wire harnesses or there may be more than
one wire of the same color. The PowerBoard
®
trigger wires need to be
connected to the factory “Door Ajar” wire that is connected to each door
latch switch. The correct wire is likely in the same bundle that is
identified in the instructions. If none of them work, you can locate the
correct wire by removing the door panel and tracing the wire bundle that
leads to the door latch.
Use an ohm meter or continuity tester to find the “Door Ajar” wire on
PowerBoards
®
with black controllers. The correct wire will go from neutral
to ground when the door is opened and return to neutral when the door is
shut. Connect one test lead to the negative battery terminal and probe the
wires with the other lead. You can use a pin or a Posi-Tap
®
connector to
pierce the wire insulation. The correct wire will make the tester go from
no continuity to complete continuity when the door is opened and return to
no continuity when the door is shut. You can also shut the door latch with
the door open by pushing on the latch catch with a screwdriver.
