SUCCESS AT LAST!
I am delighted to report that I now have a fully serviceable Gear Postion Indicator.
With the Help of Heal-Tech, I Learned the issue was with the rpm signal. Apparently, the falls out with the voltage range of the GI Pro, when the revs go above 2K.
The way round this is to not use the Tach signal, but the ignition pulse generator signal (yellow wire from the ICM).
So, the installation of this should be fairly simple.
1. Remove the following for access Windshield, Garnish, the grey pieces below the garnish, left side case, seat, Left side panel, air box cover, Left side fairing pocket, and finally the instrument surround.
2. Mount the Wheel Sensor to the rear brake caliper, in a position to be able to read the brake rotor mounting bolts, and set the sensing gap to no more than 1mm.
3. Route the wheel sensor cable to the front of the bike (cable ties supplied), and into the area above the headlights, and behind the instrument binnacle.
4. Cut a relief (optional, but looks neater) into the instrument surround to allow the cable to pass through, then peel off the protective tape, and mount the GI unit on the dash, taking the cable through to the rear of th instruments. Now you can remount the surround.
5. Now you can introduce the third part of the system, the wiring loom. Bring this to the rear of the instruments, and connect t h e two power w I res to the ignition controlled 12v supply of your choice.(connectors provided). Now take the Green/Black RPM signal wire into the LH fairing, where the ICM module is. Find the yellow wire on the bottom of this (towards the front of the bike), and use one of the provided connectors provided, follicle into this wire.
6. Connect the wheel sensor, and the indicator, to the loom, using their dedicated connectors.
7. All that is left now, is to wrap the connections to weatherproof, tidy the Wiring up, and refit the removed access items, to complete the installation.
8. With installation complete, follow the instructions to calibrate the system, and your done.
9. Enjoy the ride with your new GI unit.
