Small Tacho

[pauln]

Seeing the posts on Tiny Tacho prompted me to pass this on.
I was looking for a tacho for my Bukh DV20 and looked at Tiny Tach but in the end went for a Faria TC9281 sourced from ASAP Supplies. It is a 2 inch guage so will fit in a spare hole in the instrument panel being the same size as a standard gauge. It senses the alternator so needs calibrating via a jewellers screwdriver through a hole in the back.
I was dubious at first because it came with no instructions and the Faria site didn't list it. It doesn't come with illumination but does have a hole to fit a lamp which ASAP also supplied.
It's working fine and looks very neat on the panel alongside the temperature guage.

This is excellent way to do it as long as you have a W terminal on your alternator or know how to tap off from the windings.
My alternator unfortunately does not have W terminal and I'm not savvy enough on them to start tapping of coils etc. So I'm back to trying other methods ...

Link may be out of date but shows an optical hand held tacho for less than a fiver. Came in a nice case with plenty of reflective strip to set-up various gear.

Other item I bought after reading a thread on here .... Bike computer.

So a combination of the two should give me a good shot at sorting rev display. The handheld will calibrate the bike unit based on probably speed display to revs ... and a small table made for reference.

Now the trick is going to be finding a way to mount the sensor on the crank pulley for the Bike Computer. Thought about epoxy or hot glue gun - but reckon it wouldn't be long with a diesel engine for vibration etc. to have it drop off.

I'm also interested in knowing the shaft vs engine rate.
