So for about a month, I've had an odd problem with my 1999 Triumph Adventurer, namely that the turn signals do not work until the bike has been running about 20 minutes. After that, the signals front and back work just fine. But shut the bike down and restart and the signals are back to not working for about 20 minutes of the engine running. Fuses are good and I've swapped out the signal relay and the problem persists. While I do own a multimeter, I am sadly uneducated on how to use it to figure out the cause of this problem. Any advise on next steps to take would be most welcome, as this is my commuter vehicle and my commute is about 22 minutes long. Thanks very much!
 
Follow-up: Took awhile to find, but I fixed this finally. After replacing lots of things that didn't need replacing (bulbs, signal regulator, opening/cleaning signal switch, opening headlamp and checking wiring, etc), it turns out the female side of where the fuse goes was loose on one end. I bent it a bit with a screwdriver so that the fuse wedges in nice and tight and boom now my signals all work properly.

So in the year since I bought this bike, this week is the first that everything works as it should. I've put 4k miles on it this year despite it being off the road for a chunk of last winter and into spring.

Unrelated observation: I was in downtown Lexington Saturday, lots of people around for the UK football game, bikers on crotch-rockets, others on H-Ds. And I have to say nothing compares to the sound of a Triumph, that throaty, muscular braaaaaaaaaat. The HDs sound like lifelong smokers about to pass out. The crotch-rockets sound like mosquitoes. I wouldn't buy a bike for the sound, but now that I have this Triumph, I would have a hard time riding a different sound.
