tacho and tacho lights failure - diagnosis please?

Good question - I'll see if I can work it out later. I have an idea they do - would these relays be dangling loose inside the left side panel as that looks like where the wires go to from the connections under the tank?

OK - found the problem and nothing to do with Triumph. My fault entirely. When replacing the mirrors a couple of thousand miles ago, I must have nipped the heated grip cable with the allen bolt that goes in the base of the mirror stem.
And yes there is a relay behind the side panel.
I now need to consider whether I repair the cabling (or rather pay an auto electrician to do it), or just leave the heated grips disconnected.
Just shows how doing something simple like replacing a mirror can lead to unforeseen problems

Can you just run a new lead to the grips? I don't know what the original cabling is, but it seems you could just snip it from the circuit, and run a brand new lead.

Glad to hear you have it sussed out. Cold hands are better than, well, what would be an appropriate analogy for your gas tank blowing up right against the family jewels? I don't even know?!?!
 
I'm hoping that the auto-electrician will have the right cable for the ampage that's going to be drawn, in the right colour (pink), and the correct connectors to do a repair that is indistinguisable from the original harness. I could probably botch something up with red crimp bullet connectors :)

I really think you want to use a relay. You can draw straight from the battery with big thick wires to power the gloves (both pos/neg leads) and then just use a splice to any wimpy wire you want that will control when the relay is "on" or "off." I learned these lessons the "hard" way, trying to draw too much power from existing circuits.

It's not quite clear how it was wired up. In any case, I'm sure the repair shop can hook you up with a safe install. Shouldn't really take that long.
 
Maybe I'm just hungry but the title of this thread makes me want a TACO, every time I read it.

Glad you found the source of the troubles and are getting it fixed, I hate to trace electrical problems, I feel for ya.

GL - there is a relay. It's the proper set of Triumph heated grips. The relay seems to be controlling the power for the heat, and the switch is presumably controlling the relay. What worries me is how one of the switch wires could melt its sheathing.
