Re: [St] Speedometer woes

[Frederic NIZERY <frederic.nizery@xxxxxxxxxxxxxxxxx>]

The speedo stops working if the battery voltage is too low. Check it and check
also the voltage engine running (for a faulty generator). Should be 14 v or arround 
engine running and 12.5 v engine stoppped after sitting overnight (13.5v immediately
after cutting).

The sensor is magnetique. That is if you can disconnect it from the unit and check the output w/
a mutimeter, rotating the wheel by hand should produce pulses.

Otherwise, I guess that producing pulse w/ a square wave generator should allow to test the unit,
but I have no idea about the pulse amplitude.
