Jack not working, no ground
The other day I was moving the trailer and found my Barker jack to be dead. I messed with it a bit, but didn't have the time to properly test it. Today, I tested things and found the cause to be poor grounding. The barker jack relies on the internal connecting to the a-frame to ground, but my this isn't working for me. If I jumper the ground to a ground post on the battery or an unpainted spot on the frame, the jack works. Looking at where the mount bolts to the a frame, I can definitely see some gaps but the nuts are very tight and the connection is excellent.
Rather than taking off the jack, sanding through pain and resetting, I'm wondering if there would be any downside in simply running a ground wire from the switches to a proper ground where my remote terminals will go. I like using the bolts to ground the jack but I also don't want to futz with it more in the future if I don't get it just so.
