I have for sometime now been plagued by an erratic rev counter, I have today cured my problem with a small bit of wood. Let me explain.
I dissembled the Taco as much as you can, and sprayed WD 40 onto the back of the rev counter, ( Through the 2 holes where the little bulbs go. be careful not to go too mad and spray the underside of the glass ) also spraying the 3 pin connector that goes into the taco it'self. I reconnected the 3 pin connector to the rev counter. I then started the bike up before putting the assembly all back together, but to my dismay it was still the same, erratic, and not even registering whilst at idol speed. It was while I was fiddling about with the connection it'self that the rev counter decided to work perfectly. Now I'm no Einstein but the problem seemed to be this connection. So messing about with this connection more than a few times, brought the same result. Working not working, so it was obviously a loose connection. So I cut a very small piece of wood and tapered one end, and carefully wedged it between the 3 pin connector and the rev counter housing. I'm pleased to say that it has now cured my erratic rev counter problem, and is even registering when the bike is at idol, something it's not done for a while now.
I understand that this is more than likely not in the Triumph workshop manual, but it's just saved me £200.
My bike is a 1995 Thunderbird ( Not the sport ).
Hope that this helps someone out there
Can I just wish you all a very Happy Christmas and all the very best for a safe and Happy 2013
