Static Charge on trailer
Hi all. I put the low amp charger on the battery on the camper today and noticed after awhile that there was a charge on the trailer because anywhere there is metal I would get a small shock. Is this...

Sorry. I fell asleep last night. I took the charger and battery off this morning and the problem did not exist with the ground hooked up. But when I removed the ground there was a charge....not aa much as with the charger hooked up though. Also same results when I hook the battery back up, still some charge but not near as much with the charger hooked up.
A possible explanation as to why the addition of the charger making the problem worse: The charger is plugged into one of two phases of the 120 VAC supply. This 120 VAC phase is going to be either in sync with or out of sync with the high tension distribution line. It is not difficult to imagine that being out of phase could be making a difference. Also, the charger may also be adding inductance to the capacitance equation by virtue of having a step down power transformer UNLESS it has a switching power supply.
There are potentially many many many variables at play which can all be resolved with one properly connected GROUND to EARTH bond.
