K16 reverser system, how does it work?

[AntonLargiader]

I'm trying to diagnose a bad reverser with practically no information. Is anyone aware of a schematic for this system?

The bike has the typical blinking red R going back to N. There is no attempt at anything mechanical as far as I can tell. No noises, clicks, nothing.

The most commonly replaced part is the control unit, which seems to send power to the starter motor. There is a drive cable that takes the starter power down to the gearbox.

The other significant component is the drive mechanism which has a motor and linkage to engage the reverse gear in the transmission and lock out the shifter. This has a 4-wire connection to the main harness. Since it does not move, my suspicion is that this part is bad and the reverse process never even makes it as far as sending power to the starter motor. However, I don't know all of the chicken/egg relationships in this. The drive unit has red, brown, purple/green and purple/white wires. I figure the two purple striped wires are limit switches.

Does anyone know: If the control module is bad, will the drive mechanism still try to engage?

My GTL currently has this problem. Mine is scheduled to be seen on 8/22 to confirm/deny it's the module, as Morton's techs suspect. My understanding is that a dead control module does not send out a signal to activate the lockout mechanism.

Thanks. So it sounds like you have no sign of life from your lockout mechanism, right? I wish you were going there tomorrow!

Correct -- not even a sound from an actuator trying to move the lockout mechanism. The mechanism also cannot be manually rotated into engagement (tranny in neutral, of course).
