Witt DMC 2 Optical Sensor...... Sod's Law dictates!

[Tony]

Some of you may recall that my RGS left me stranded in Warwick last year. I was rather upset at the time?

No sparks coming from my Witt DMC 2.

Our Keith diagnosed the problem from afar and told me to ?Get a grip? it?s just a component failure and that a new optical sensor for the princely sum of ?8 would sort it.

I needed the bike running ASAP at the time so I pulled the Witt off and re-installed the old Bosch setup for a while.

That was then. This week I finally got around to ordering a new sensor (I bought 2 actually) and Yes our Keith was spot on!

As I now have a spare and as Piet says they are small and could easily fit in your tool roll and ?at a push? be fitted at the road side.

They problem is the sensor has 4 wires and has soldered connections in the harness to a 3 wire plug on the Witt that would need to be cut off to pass the wires through the hole in the stator plate.

So I?ve ?Got a grip? and altered mine!!

I?ve attached a couple of pictures showing the slot that I?ve cut in the plate and my new spade connections. My logic is, if I?ve got a spare sensor under the seat that I could easily replace by the side of the road then Sod?s law dictates that I?ll never need it!!

Peace Out

Hi Tony and the "Others".

  Is an optical sensor available for a 180 triple ..... My WITT 2 still uses the old pickups

Tim,

The DMC I and II units fitted to MkI triples use the original pick-ups.
DMC I units for the MkII triples also use the original Bosch pick-ups.
DMC II units for the MkII triples use a single optical trigger.

Well done for getting that grip our Tony 

Can't see it being significantly hotter on the right side of the engine compared to the left. I have modified an early triple to run with an optical Witt by making my own stator plate and trigger, it still working fine after several years, also adapted one to fit my sfc elettronica not had any temperature related problems, I think manufactures tend to cover their arses a bit when writing their technical specs.

Should have added;

Mr.Witt is currently working on an alternator base plate to replace the original MkI pick-ups.  The new version will use a single generic hall sensor, retaining the original alternator.  First prototypes have been running successfully since last spring (it's his policy to thoroughly test his products before letting them loose on the world!).  Don't have a clue though when production is planned.
