Hello out there,
I am new to the forum and have a problem my head can't get round.
I have just dropped a K75 bmw motorcycle engine into a reliant fox car. Double the horsepower, double the fun
anyway, The bike engine has a gear position switch on the gearbox which uses 4 wires.
yellow / black, Yellow / blue, Yellow / white and a common black earth. Combination of the wires shows which gear your in. I am looking to install a standard numerical display on the dashboard to show the gear, but I can't get my head round (probably down to still wiring the engine electrics)
The numerical display has numerous wires that when earthed show the number or N for neutral.
this is the list I have got for the wires. Bike wires on the left, indicator on the right
Yellow/Black and Yellow/White grounded = 1st gear - Brown & Yellow: 1st Gear
Yellow/Blue and Yellow/White grounded = 2nd gear - Black & Green: 2nd Gear
Yellow/White grounded = 3rd gear - Green & Blue: 3rd Gear
Yellow/Blue and Yellow/Black grounded = 4th gear - Yellow & Blue: 4th Gear
Yellow/Black grounded = 5th gear - Brown & Red: 5th Gear
Yellow/Blue, Yellow/Black and Yellow/White all grounded neutral - Green
Any ideas how to do this and give my head a rest??? Do you think I need to make a printed circuit to sort this or can it be accomplished with relays?
Thanks in advance
