Just got a price from Honda for a new one.
**UCK me - was more than three figures.
Time to email a load of breakers.

Right - this is Andy's MNR and he has the early blade clocks with the needle temperature gauge (not digital) and is using the sensor from the
later blade that bolts through the crankcase with two magnets on the prop shaft adaptor and a speedo healer and it all works fine.
So.... Both the older sensor with the wheel and the new sensor that bolts through the crankcase must give the same signal down the wire (unless the
speedo healer compensates massively).
So... In theory, any sensor should work that gives off the same pulses.
Still go to get myself a sensor like the one in the pic, but it's great to know I can utilise all the blade clocks and very easily using the
later speedo sensor.

Gents,
Ive attached a word doc explaining how i resolved the pick issue using blade clocks.

Sorry, I don't see how this picks up any rotational pulses and how the sensor works and is mounted???
I have spoken to "Speedo Healer" now on a few occassions - very helpful guy and he has said that a reed switch, or a hall effect will
work, as long as the input to the speedo healer is less than 5v and pulls the signal down to ground when the magnet passes.
I have found an original speedo sensor so will test further when it arrives.

yeah
Just an ordinary
microcontroller in an case
And offcourse 1 pot to be able to adjust the devide quantity..
sample an 16F819 and do it your self..
Needings
- 1x 16F819
- 1x 7805
- 2x BC547C
- 2x 10KOhm resistor (7 to 15K)
- 1x 1K Ohm res (500 / 2K)
- 1x Pot 20K/Ohms
Hooking it up is straigt forward...
the pot in series with the res on the 5volt line and ground..(depending on our program we can then mannage the value with the number we want..adc
value will be between 0 and 1024(10bit) sow enough steps possible.)
(adc port, adjust)
to porta.o channel an lead (coming from the pot/res connection)
vdd= 5volts 7805 output
vss = 7805 middle pin = chasis connected
7805 input = 12volts...
(input)
portb.0 connect it to 10K to 5volts..
connect pin also to collecter (pin 1 of the bc547c)
connect the middle with the 1k ohm to the sensor lead..
(output)
Connect portb. 4 to the other bc547 middle pin)
connect the collect to ground and the emitter is the input of the clock
(output of the unit)
then whats left is program the chip with an simple program....
(can make it for you in 5minutes)
Tks
ohja total costs will be less then 4 pounds....
what costs an healer unit?

Ok, so I am guessing that bit replaces the Speedo Healer.
Any suggestions as what to use for the actual pickup and where to mount it?

Looks good to me.
I guess that if as I have I've already wired a speedohealer (yellow box) in, that I could leave the frequncy divider off, paint just 3 limes on
th prop then tweak it with the healer?
Thanks for the info, my mans not got back to me yet.....

Whats a frequency divider?
I still like the simple idea of the original later sender, 2 magnets and a Speedo Healer.
