Battery tender tripping GFCI
This is weird...
I have a Battery Tender Jr that's 3 yrs old (large brick) and another that's a few months old (new design, smaller brick). Old tender is attached to my generator, new tender to the Low Rider. Suddenly today, the new tender trips GFCI the instant I plug it into the bike. In doing some troubleshooting, the new tender works fine on the generator (no GFCI over there). And the old tender works fine on the Harley, no GFCI issue. OK, so maybe the GFCI outlet is bad. I have a second circuit in the garage, also GFCI, so I plug the new tender in there. POP.
So I have a mystery.

- New tender + bike trips any GFCI.
- Old tender + bike works fine in any GFCI.
- New tender + bike works fine as long as not plugged into GFCI.
- New tender + generator works fine in GFCI.

I measured the output of both tenders but nothing is registering. If I understand these things correctly, they have to read input voltage from the battery and then determine what to output. As of this morning, everything was working normally again. If it goes wonky again I'll have to give Deltran a call.

Sounds like your new battery tender has a problem, go to Walmart buy a new tender and plug it in to the electrical plugs you want to use and it will tell you if it's the plug or the tender.....you can't blame the electrical plug for doing its job....have you plugged an air drier in the electrical plug to see if it triggers.....hair drier draws more power then tender, if the plug isn't bad it will not trigger.
