Where's the crankshaft position sensor on a Trophy 1200 located?

How would one go about changing a bad one...what's involved?

Damned Triumph manual doesn't even mention it anywhere that I can find. :evil:

Its located behind a round access cover on the right hand side of the engine. Very easy change out, it just unplugs from a socket, and has a screw holding it in place. You must set up the air gap correctly. I cant remember what the correct number is for this presently, if know one else responds, drop me an email and Ill look it up for you. Very simple change out.

Seeker,

If you have the Haynes manual it is called the pick up coil and the gap should be 0.6-0.8mm. If you know how to use a multi meter, the resistance of the coil should be 530ohms +/- 10%.

Hope this helps.

This information might be under the same heading in the Triumph service manual.

Good point on the resistance check there tango, I bought a brand new one once for my Trophy and it was bad from the factory. Its an easy change out Seeker, if you can change a light bulb, you might stand a chance at getting this right.

Thanks guys.

I emailed Swampyankee (some may remember him here) and he was kind enough to fill me in on it.

Yes, in the manuals they call it either the ignition sensor or the pulse sensor. That's why I was having trouble finding it.

I had a suspicion that they were all one in the same but I wanted to be sure before I bought one.

BTW: My bike is proof that they don't ONLY act-up when the bike is warm/hot. My bike was running perfecty one evening. I parked it overnight in my garage and it refused to start the next day. I have a heated garage but the heat was turned-off, so the garage temperature was about 53 F.

Chilling the sensor with brake cleaner or something cold wasn't going to help it and only through a long process of elimination caused me to figure it had to be the ingintion sensor.

Replaced and set now - the bike started immediately and ran flawless again.

Oh well, now I have new plugs, oil, fuel filters, fuel lines, vacuum line, battery, a cleaned petcock valve, and everything else gone over with a fine toothed comb!
