I have been using a LC1 with my MSnSE for several months and 1000 miles with no problems. Then one day I realised it wasn't working so I bought a new sensor and fitted it but it doesn't work either. My LED doesn't light and the sensor wont heat up. I have checked the power and earth leads and all seems fine.

Any ideas on what has happened?

I haven't really got a clue. maybe contact who ever you brought it from and see if they can suggest any checks you may be able to do. It may even have a fuse inside.

I had the same problem last year. Innovate replaced LC1-unit without any hazzle.

I not that uncommon, have a look at their forum and you will see that you ar not alone
