Charles,
Thanks for the additional instructions. I spent some time today trying to get
the tach counter reset -- no luck.
I soldered in header pins into the empty socket location on the tach board as
you mentioned -- basically this winds up being a connector in the same place as
on the chron, cht and fuel displays right? Then I took a rotary switch [in my
case, the one from the chronometer] and connected it to the tach board.
I tried several combinations to see if any update would happen:
- as specified, start in position 5, wait 60 seconds, then positions 9-6
- same thing wait a few seconds less than 60 before moving the switch
- same thing wait a few seconds more than 60 before moving the switch
- try doing the motions right after power up
- start in position 9 at power up
- [and a few other combinations]
- also remove the other displays from the cable chain
In all cases, no change to the counter values. So, questions:
- do you expect the tach display to be other than the accumulated value right
after power up [e.g. during the 60 second init phase]? e.g. any special string
displayed there?
- do you wait exactly 60 seconds after power up, or a few seconds more?
- did you remove the other displays from the chain?
- did you do anything special to the ribbon cable during the process?
- do you think there is a difference in the rotary switch between the
chronometer switch and the cht/egt switch?
Curious.

As I mentioned, here are the instructions re-typed.The instruction sheet I had was a fax of a bad copy in Feb ’07. It would take me longer to fix the OCR than retyping, so with retyping it is included below.
