Happijack 4150's stop?

Question

Hi, hopefully not for some guidance please. My jack motors run slow for several seconds then stop. I have to unplug, replug and go again. I bought my 03' Northern Lite used and there's no instructions. I had to replace two motors from Happijack so I know the motors are good. Battery is also good although a few years old. Any suggestions or is the system built this way? Thanks

Sounds to me like high resistance (corroded) connectors.  I keep mine clean and apply di-electric grease to r e t a r d corrosion.(certainly not a bad word but censored anyway...lol)

Additionally, I keep my unit shore powered when running the jacks (and the house batteries) as well.  Running the jacks on just shore power (no battery) is hard on the converter and I've noticed that if my remote's batteries are low, my jacks stop and then restart.  A fresh battery cures that.

Another possibility is the jack screws are corroded. Do the turn freely when operated by hand?

Another possibility is that automatic circuit breaker trips and the timing with pulling the plugs is just coincidence. You need light probe for troubleshooting.

Thanks, I'll pull my boat batteries and try them to see if that's the cause. Other ideas are also appreciated. Yes, they turn ok by hand.
