guages

can anyone confirm if there are ANY blank spots or missing wires on either the guage side or bike side of their wiring harness for their fully functional gauges?

on the guage side of my harness there are 6 blank terminals. on the bike side of the harness there are two blank terminals. both blank terminals on the bike side of the harness match up with two blank terminals on the gauge side.

the other four blanks on the gauge side, have wires fed into the connector on the bike side for them.

hope this makes sense.

just trying to decipher if my gauge is bad or if its the harness.

my guage appears to be fully functional EXCEPT the orange backlight doesnt glow so i cant see shit at night.

If your meter works, and your tail light works, then the 10A fuse E is good (meter-illumination-tail).
I'd check the electrical contacts at the meter side for tarnish, and put a dab of dielectric grease on the contacts to prevent tarnish or corrosion.

They both work. Grease the connection right at the gauge? I greased every connector that was easily accessible a few weeks ago but not the one right at the gauge itself. Just puzzeled why everything functions on the gauge besides the orange glow. Even the fi and fuel light work.

I wouldn't imagine there would be one single wire for the backlight alone, but maybe.

No separate wire for the backlight.

You can try this.
Remove the connector from the back of the meter.
1) Check the two black/brown (+) wires to ground for voltage.
These are the main meter/backlight power supply wires.

2) Check the Green wire to ground for continuity at all times.

3) Check the Red/Green (+) backup voltage line to ground for power (this is if the odometer doesn't work).

If all check out, your backlight has failed.

There are two solid green wires and three black/brown wires. Do I check all of those?

So two of the three black/brown wires had 12.5 volts and the green/black wire had continuity

Green is ground.
According to the wiring diagram, there are 2 black/brown and 1 brown/black wires.
The 2 black/brown wires tie to a point on the harness, so they should be the same voltage.
The brown/black wire ultimately goes to the fuel pump.

As the 2 black/brown wires fork from a common point earlier on the harness, they should both be at the same voltage. In this case 12.5V, which is battery voltage.
The green/black wire goes to the main chassis ground point on the right, behind the rear cowl, just above the right rearset.

ok, so they all tested good, so in your opinion the backlight simply crapped out?

was just trying to clarify if it was a harness problem, or display problem with this thread before I spent money on a new gauge.
