Your tachometer only has two wires.

1. A Yellow/Blue wire from the ECM, passes through a Black 13-pin connector behind the right fairing pocket and a white 20-pin connector behind the instrument panel.

2. Ground wire from the frame.

Sometimes the Tach's get lazy and don't start registering for a few minutes after the engine starts.....!!


I am glad you got things working good. Always good when a plan comes together...!

Thanks very much!

After ten minutes, still nothing on the tach.
Can you say where the ECM is?
And do you happen to know where the ground point is on the frame?

The ECM is located behind the right inner fairing panel (the panel by your right knee). Opposite the panel for the reverse lever....!!

The Tach uses the same ground as other items you have working in the instrument panel.

I kinda doubt it is a ground issue......!


Heading to bed.....I'll check on your status again in the morning....!

Thanks again!


So, the bike runs, the tach and the speedo do not operate on the dash cluster. No speed.


Also, of interest, when kicking into 1st gear, it kills the engine.
When attempting to start again, in gear - it will not run.


Back to neutral, and fire it up, no trouble.


This is a first...Its almost as if the kickstand is down, but in reality it isn't.
Again, all lights, and gauges are lit and reporting temperatures and fuel state.

Sounds like you have a faulty "side stand switch"...............!!


Look at item # 6: https://www.partzilla.com/catalog/ho...spencade/pedal

Special Note: Before purchasing a new side stand switch, check for continuity to ground on the Green wire at the side stand switch. There should be continuity....!


When the transmission is in gear:

1. Voltage (brown/white) wire from the #9 start/reverse (5-amp) fuse goes to the reverse lever switch,
(black/white) wire goes to the neutral light bulb and the reverse diode assembly, (yellow/red) wire
goes to the reverse relay switch. (This is voltage to “trigger” the reverse relay switch)

2. Ground (green/orange) wire from the reverse “neutral” switch goes to the reverse diode assembly,
(black/red) wire goes to the reverse relay switch. (This is ground to “trigger” the reverse relay
switch) Note: It also provides ground (green/red) wire to “trigger” the starter relay switch B.

At this point, you have input voltage and ground to activate “trigger” the reverse relay switch...!

3. Ground (green) wire from the frame goes to the side stand switch, (green/white) wire goes to the
clutch micro switch, (green/red) wire goes to the reverse diode assembly, (blue/red) wire goes to the
input “load side” of the reverse relay switch.

When the reverse relay switch is activated “triggered”, ground passes through the reverse relay switch
and ground goes to the starter relay A. (This is a “brown/red” wire at the starter relay A)

When the side stand is up and the clutch lever pulled in, the ground circuit is completed to activate “trigger” the starter relay A.

(The bike will start in gear)

Check/clean the "ground points" on the "radiator" and above the "oil dip stick".

These are the two ground points for the speedo and tach.

Note: You do have all the connectors behind the instrument panel "clean and tight"...."no bent/broken pins etc.".....RIGHT.....???

I had that happen on my 1990... turned out be be a bad Common Ground: https://www.goldwingfacts.com/forums...d-gremlin.html

Same problems occurs on 1800's, which use same connector

Thanks - will check all of these this afternoon (PST).


I should mention, she was down hard on the the shift lever side - does this new information cause you to re-assess your previous thinking?

Also do this test: Temporarily connect the "Green" and "Green/White" wires together at the side stand switch. Does the engine run in gear..??

No....follow post # 16 and 17.
