The pdf manuals I found online that tell me, how to diagnose DME
problems, reference a 'Speed Transmitter.'

Here's some info on what I found while diagnosing it.

Resistence against term 27 and term 8 should be 0.6 kohm to 1.6kohm.
Mine is intermittently (meaning when it doesn't get a spark ergo
doesn't spark) 9kohm - 12kohm

The insulation resistance from term 8 and term 5 should be <1 M-ohm
Mine is infinite.

At any rate, I attempted to find the speed transmitter part online, at
pelicanparts and at vertexauto, and unfortunatly have had no luck.

Is there something else it will be called? Or is there somewhere I
should look?

Thanks guys,
-Alex

I have 84 944. Here it is called a speed sensor. Maybe not the same?
Look here for details :http://www.clarks-garage.com/

These sensors work loose and need to be repostioned with reference to
the timing mark pin and ring gear. Clark explains it.

Well I found the part -- Unfortunatly it must be .8 mm away from the
flywheel.

The manual says to find something that is .8 mm thick and glue it on to
the bottom of the sensor and later take off the .8 mm thick thing.

What have you guys used in the past to measure this?

I don't even know how to measure anything that is less than a mm

Thanks
Alex

Go to harware store and buy a set of feeler gauges. Metric and English.

Match Book cover?
Measured with a Micrometer?
