Control Unit Replacement
Install a new control unit if the turn signal switch is still not
cancelled automatically.
Remove the air cleaner case and air cleaner element holder.
Place a rag or shop towel over the air chamber to prevent entry of foreign particles.
Remove the ignition control unit and relay bracket.
Remove the ignition coil.
Disconnect the brown coupler and remove the control unit from the bracket.
Install the new control unit.

One unit, time control is located up near the coils in the upper forward frame the other, angle sensor is located below the steering head at the front of the bike under the fairing.

That's a very good point Tricky. When guys send me personal emails for tech requests I just copy and paste them out here and give them a link in response. It's just not fair to not share good info with everyone.

NOTE:
Before going into detailed inspections, first check that the sub fuse is not blown.
Also check that all wires, cable, and connectors are not loose or disconnected.

System Inspection
Test ride the motorcycle and check the system while moving. If the system doesn't operate while moving, check the speed sensor, page 18-36 (Aspencade), or the lead switch, page 18-31 (Interstate).
If the speedometer sensor or lead switch check ok, check the angle sensor and turn signal control unit.

Angle Sensor



On Interstate and Aspencade remove the stem bottom cover and reinstall the screws.
Turn the front wheel from right to left and check the angle sensor for wear or looseness.
If the sensor is worn, replace it, and if it is loose, tighten the mounting
screws.

Remove the seat and top compartment.
Disconnect the brown control unit coupler



Turn the ignition switch to ON and push the turn signal
switch to LEFT lock.
Connect the BlueIBlack and BrownlWhite terminals in the
wire harness side connector with a jumper wire.
If the switch returns to neutral (cancels) it is normal.
Check the switch in the RIGHT position in the same way.
Also check to see if the switch operates smoothly.
Turn the ignition switch off.



Solenoid Wire Harness



Disconnect the left handlebar switch coupler located inside of the fairing on Interstate or Aspencade or in the headlight case on Standard.
Check the continuity on the Bu/BI and G wires between the brown coupler and the black coupler.
Between same colors: Continuity
Between different colors: No continuity
Check the continuity between Blue/Black and Green in the brown coupler.
Between Blue/Black and Green: No continuity
Reconnect the black and brown couplers.


Main Turn Signal Wiring Harness

Turn the ignition switch to ON.
Disconnect the brown coupler. With the directional switch in each position, measure the voltage between the Green and BlueJ/White contacts. Then the Green and Orange/White contacts.





Turn the ignition switch off

Angle Sensor Harness

On Interstate and Aspencade, disconnect the angle sensor coupler (3P white) located inside of the fairing.
On Standard, disconnect the angle sensor connectors located inside of the headlight case.
Check the continuity between the angle sensor harness terminals and control unit brown coupler terminals.





Angle Sensor Resistance

Measure the resistance of the angle sensor at the angle sensor coupler or connectors.

Resistances:
Between Black,Yellow and Green/White: 10-19k Ohms
Between White and Green/White; Resistance should
increase steadily when front wheel is turned slowly from
left to right (resistance should not change suddenly).



Angle Sensor Sub-Wire Harness
Remove the angle sensor from the steering stem.
Check the continuity, end to end, of each wire.
Between same color: Continuity
Between different colors: No continuity



Lead Switch Inspection (Interstate only)
Remove the instrument panel.
Disconnect the lead switch wire connectors.
Check for continuity between the terminals by turning the drive shaft one full turn gradually.
If the switch makes and breaks continuity four times during one revolution, it is ok.

Thank you Gentlemen for your time and effort, it was much appreciated! Special thanks to Tricky for the technical diagrams!

Hey Tricky,
where did you get such nice diagrams and illustrations from? my book is... well, crap.

I pull them in from Tokyo :roll:

New to the Forum and new to my 85 GL1200 Aspencade. On the way to work this morning as I was merging onto the interstate I noticed the left signal indicator sort of flickering as it blinked. When I got to work I looked at things closer and found that the left indicator now stays on and just sort of pulses when the signal switch is on. The front turn signal goes dim and pulses - and the headlight pulses with it! It didn't look like the rear turn signal was on at all, but then the morning sun was from that direction. The right turn signal works just fine. I have no clue where to start other than with the bulbs, then the fuses then...?

[admin]

You're on the right track, check the fuses, bulbs, flasher, connections, switches and controls and tell us what you find.

[Wing nut]

Thanks, I'll check those things out over the next couple of evenings. In the meantime it will be hand signals for the left or all right turns! I don't care for the headlight dimming and pulsing, makes me feel like there is a lot of juice going somewhere it doesn't belong.

[admin]

A bad ground can cause the dimming headlight. It's going to take some careful inspection on your part to find the problem. Good luck.
