Dying new tongue jack

[Johnnyfl]

Just installed a new tongue jack and a new battery to my tt. The jack works very weak and dies for some time until next try. I just plugged and play since I got the same tongue jack. Not even connecting the truck wiring improve the jack. Only works right and strong with the shore power. Where should I look?

First check the battery. Make sure it is charged. Next check the power connection. There maybe corrosion.

I see this is your first post so welcome to the community. What kind of camper do you have?

If battery and connections are good, check the wire size for the power and ground. Do they get warm while using then they are too small.
