I need a Gear Position Sensor GURU for this one

[r3badboy]

Well I pulled it apart again and did some testing, Black/White wire is neutral switch (ground this wire for neutral) and the black wire is the gear position (different resistance for each gear). The approximate resistances for each gear is 1st=85Ω, 2nd=180Ω, 3rd=380Ω, 4th=680Ω, 5th=1200Ω and the nonexistent 6th=2740Ω. I am having the same issue motioned where my indicator shaft has lost the roll pin connection to the shift drum and is free wheeling. I made up a temporary (which may just stay permanent) switch to select 1, 4 or N using a SPDT center off switch and a couple resistors (see hand sketch diagram). With switch down it simulates being in Neutral by grounding the black/white wire, center off position the ECU sees 4th gear through the 680Ω resister to ground and in the up position it parallels the 680Ω & 100Ω resisters to ground (about 87Ω) causing the ECU to see 1st gear. I think I will mostly use the N & 4 positions unless maybe if running around town...

You lost me at wire

Just some info
Some used to use a resister to trick the ecu into thinking that it was allways in 5th. They seem to think the the lower gears was restricted so this resister was used.
All u need is a neutral ground to start then unground to run good when in any gear.

I had to take the cap and spring out and clean. Then clean the contacts.
And no more problem.
