My power outlet on the left side behind engine stopped working after I tried to put a battery tender on it. I checked the fuse box under the seat and all were good. Can anyone help me on this?
 
The power outlet plugs into a little plug on the wiring harness, and maybe when you installed the battery tender, you loosened that plug accidentally. I would check that first. I suppose another possibility is that you shorted something and blew a fuse, but that's easy to check too.
 
I'm not sure that outlet is meant to be used for a battery tender. I've always run a separate cable to the battery for mine.

It should be fine for a tender as its on a 10amp fuse, pretty sure tenders don't output that many amps.

I would look at the tender plug, have pulled the wires on mine a couple of times.
 
If the fuses are good, check to see that you didn't loosen the plug at the wiring harness. That's right behind the outlet. I really think that's the most likely scenario.

As for using the outlet for a battery tender, it is just fine for that purpose. Optimate badges one of their units with the Triumph marque, and Triumph sells them. You can buy a plug from Triumph, with a Triumph part number, that will plug right into the powerlet plug to connect the Optimate and tend the battery.

I have both the Optimate and a Battery Tender. I have a pig tail on the battery of the R3T, and I have the powerlet outlet there on the left side. I generally use the Optimate unit through the powerlet plug on the R3T, and I generally use the Battery Tender on the supermoto, lawnmower, etc.
 
I have the adaptor for the European plug that converts it to a regular plug. I did not see any wires loose. I will have to recheck fuses I guess. It happened about the time my heated grips shorted out.
 
ok, using a meter, I found a bad fuse. Get this. This fuse not only controls the Aux, but the Heated Grips AND the memory on the Trip display.
