Troubleshooting Ram Electric Jack Lights Working But Jack Not Operating

Question:

We have as RAM 3500lb Capacity Electric A-Frame Jack EJ-3520 that quit working. Trying to troubleshoot. LED Light still works but no power to extend/retract. Works fine manually. If the light works does that mean the 30 amp fuze is good? What about the switch? Any suggestions would be appreciated.

If the light on your Ram Electric Jack w/ Footplate # EJ-3520-BBX is working but the jack motor is not actually getting any or enough power to operate, I first recommend checking to make sure the power source is good. Make sure the battery you are using is fully charged and in good condition. If the battery is good, check to make sure you have a solid ground connection to a clean, bare metal surface. A weak ground might be allowing for just enough power to reach and power the lights, but not enough to fully operate the motor.

If the battery and ground look fine, then it's possible that the switch is simply bad so it is not allowing power to get to the motor when used. If this is the case, you can use the Replacement Power Switch # EJ-3520-PSW.

If you are still having issues, please let me know and I will be happy to look into this further.

Since the jack works fine when being raised and the light is illuminating, we know it's getting good power and that the internal gears, etc are in working order. This leads me to believe it's really just a switch issue. Replacing it with part # EJ-3520-PSW should resolve the problem.
