Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.

Hey MArk,
Reinstall your starter...when trying to start your bike, voltage means almost nothing! - The "quality" of a battery is determined by the CCA (Cold Cranking Amps).. amperage is what makes your bike start...and you need at least 13.5 volts to run the lights, etc..
O'Reilly's, AutoZone, etc.. can test your battery..
..When you get a new battery...you need to check the charging system.. crank it up..let it get warm..then put a multimeter to it..Red to + terminal and black to - terminal ...you should get 13.5+ volts DC to the battery at 3500 rpm..

Check connectors first, because the lights on a bike all tend to feed off the same fuse. At this time of year water can get into the connectors un the underseat area and around the back end. A good liberal spraying of WD40 is recommended at this time of year. The symptoms you describe show a deteriorating problem, so the most likely cause is a bad connection or water ingress. good luck and keep rubber side down.

I don't think it's an electrical ark: it it would be one the current needed to create a spark so loud that you can hear over the sound of the engine with a helmet on would be so great that not only all the fuses would have been blown but the voltage in the electrical system would drop so low that the engine will surely cut out. And if it would have occurred once the second time would have been the last one - a short that big would have melted and welded the cables
Much more likely is that it's a noise made by a bushing, somewhere in the general location of the sound. start by shaking the head lamp and the bad and look for loose rubber or electrical hoses. Then have the head tube and its bearings inspected, check the triple clamps and inspect the shocks. Finally check the mounting supports for motor and the exhaust tubes - they might expand from the heat and rub on the bolts.

It is a hydraulic in line pressure switch that seem to go bad often on the triumph. Check the assembly on end of the of the rod that runs from the rear of the rear brake pedal up into the rear brake cylinder. If the nut has worked its way down, then the pressure could be constant enough to make the contact stay on.
Turn the lights on and work the break pedal up and down with your hand to see if it goes off. If it does not, take the pedal off and see if an adjustment to rod assembly makes the brake light go off.

Good luck, i hope this helps.

Your carb float is sticking, which will allow fuel to keep filling the bowl, even though it's full, thus the excess fuel will overflow into the air filter. You can try to "tap" the side of the carb with a soft hammer or wood to free itup, if that doesn't help, they need to be taken apart to free up and clean out the float needle, and jets. (Pilot and main jets per each carb)

Take some petroleum jelly and run it on all the wire connectors. That will waterproof them for a LONG time at low cost.

The side stand kill switch may be out of position, Starter button wire has come disconnected somewhere along the way? Is there power from the button to the solenoid when the button is pressed. If so, get a new solenoid. If not, trace the wire back to the button and find where it has come disconnected.
