CAUSE
SOLUTION
Open Circuit Breaker
Wait 15 seconds for the breaker to close.
Poor Ground
Clean area between the jack mounting plate and coupler, and
ensure paint has been removed by the star washers. Direct metal-
to-metal contact must exist between mounting components to
ensure good electrical contact.
No or Low Voltage
Check battery& electrical connections. Power supplied must be at
least 10V DC. If the battery is low,plug the trailer cable into the tow
vehicle,and start the tow vehicle to provide power to the jack.
Blown Fuse
Replace fuse with a new 30A fuse.
