Larry, Our concern is not if the light works, If you look at the switch you should notice it is a single pole double throw switch. We are concerned with the part that tells the ECU the stand is up. Not the grn to yel/blk that turns the light on. Read the post right above here. #6 AT THE ECM must see ground or it will shut the engine off when you put it in gear What if the grn/wh is broken. The jumper will serve no purpose. It is just a beginning point to test only the switch. Now you need to test the wire.

Larry, Do you have continuity to ground on the Green/White wire at the clutch micro switch (with the side stand UP)...???

If so, your side stand switch is good.

Next (with the side stand UP), check continuity to ground on the Green/White wire at the following locations:

1. 22-pin Red connector under the seat, right rear corner.

2. ECM connector.

Easy things first.........!!

Let us know your results.

As some of you know I'm an auto mechanic and I started years ago in motorcycle repair, so I am smarter than some but definitely don't know it all.

I have 1.7 v using power probe on this wire. Put into reverse I get bat. votage

If the voltage test on the green white fails the wire has an issue between the plug and terminal #6 of the ECM.
Unplug the side stand switch, bike side plug, Green 2.7 v using power probe, Green / white .7 v plugged in side stand down same as unplugged, side stand up 2.7 v moves to green whit wire. throughout the bike

With everything electrically connected (as factory wired)
Side stand Up
Reverse lever set for forward drive
I have 2.7v using power probe at
green/whit wire everywhere, (side stand plug, clutch micro switch, ecm, and 22 pin red connector.

If I send it a ground (from power probe) I can put bike into gear and make rear tire spin on center stand, but radio still mutes.

I have cleaned all bat. to ground connections that I can find too!

Update....
Now one more interesting thing Green wire at bike side of side stand switch has a great ground signal with key off, turn key on and it switches to 2.7v

With the reverse lever UP, you should have battery voltage on the white/blue wire. (Looks like you are good there)



Unplug the side stand switch, bike side plug, Green 2.7 v using power probe, Green / white .7 v plugged in side stand down same as unplugged, side stand up 2.7 v moves to green whit wire. throughout the bike

I asked you to check continuity to ground (not voltage)....! Did you check continuity to ground with an ohm meter....??

It seems to me you have a poor ground connection. That ground wire from the side stand switch goes through a couple of connectors before it finds a ground to the frame. I think the most likely candidate is the C192 connector. It has a bunch of wires going into it from various circuits and they all have a common ground point. That connector is taped to the wiring harness on the left side by the fuel tank. It has been known to get resistance in the connector and cause poor grounds. I would try to find that connector and test it there.
Here is a link to a thread about that connector that another member found was causing problems for him.

That is a bad ground period. A good ground will never have voltage by definition. It is probably a bad ground that can sustain the minute power of the Volt meter but when real power is applied it fails. Ground that green to the frame somewhere and try it. Or better yet just ground the green/white and try the bike out.

I have checked the grounds at the frame from the bat and the fused ground and the orange group of grounds on right side, Ill look for the left side one tomorrow and will start going threw all the connectors, hopefully I locate the problem wire soon.

Just in case there was / is any confusion a power probe is a verry nice tool that can almost replace your multi-meter. for more information go to http://www.powerprobe.com/webstore/i...ry&path=69_152 and read about them

When I found no ground on the green wire I switch from a meter to the power probe because it will tell you more in a single test then the meter can. example the meter told me i had .01 resistance to ground on the green wire (Key off) but I had infinity (no continuity) to ground with the wire (Key on) power probe told me key off great ground, key on 2.7 volts of + power.

FYI Mr. DBohrer the whit / blue wire never changes from idle to 5 grans on tack, it stays at about 1.7 v unless I move the lever to reverse then it goes to bat voltage.
Also Yes I did check continuity to ground with an ohm meter.... before I switched to my power probe.

yep as posted five back I have tried it, and I can shift into first on center stand didn't try second or more, but as soon as I shift it out of neutral I'm still loosing the audio. I didn't try putting it into reverse again with a ground jumped but I still have not found or fixed the problem.

thanks though

Like Larry (Bellboy) said. Check on the left side of the fuel tank and find an orange gang connector taped there. The problem is most likely a bad connection in there. It would affect both the engine and mute the radio. https://www.goldwingfacts.com/forums/...d-gremlin.html Should be the orange connector on the left side but there is same on the right side.

Its not supposed to change with various RPM ranges........!

I move the lever to reverse then it goes to bat voltage.

That is what it is supposed to do..........!
