Replacement Circuit Board for a HappiJac Electric Truck Camper Jack

Question

Question:

The left front fuse port melted due to a shorted motor. I replaced the motor only to find that the circuit board got toasted. On this board I do not see a model number. In your videos they refer to your original circuit boardinch and give the replacement board information. HJ info, 733513. I have looked through the Q/A and kinda see the answer. I attached a few photos for clarity. This truck camper is a 2017 Northern lite 8-11, no doubt the year of the board and controller. I need a controller, but do I need a new remote too? I hope not, everything is so high in costs.

No, you won't need a new remote, however for a replacement circuit board you're going to want the Replacement Circuit Board for HappiJac Electric Truck Camper Jack Systems # LC733513 which is going to be a direct replacement.

@Gregory Gregory, on the control board itself there isn't a reset button, but what you can do is press buttons 5 and 6 at the same time on the remote, and ACC. IN and ACC. OUT simultaneously to initialize the system.
