Clutch Switch Issue

[MDGeorge]

On the new trike...
2012 GL1800, Viper.
The clutch switch is suppose to prevent you from starting the bike in gear. This is a good thing and as it should be.
However, on mine, the radio cuts off when I put it into gear. Actually all sound cuts off (iPod, Navigation). Like the sound is tied to the starter.

Any ideas?

When the clutch is released (let out) and the bike is in gear, you cannot start the bike.

My sound and maybe other things cut out when the starter is engaged, even when reverse is engaged.

I think I misstated the issue.
It starts fine. No issue with the starter.
The only issue is the sound cuts off when I put it in gear.

radio only plays when bike is not running ??.?? Is that right??.

Almost right.
No sound item works if the bike is in gear.
If it is in neutral, or the clutch is pulled in, or the bike is not running, everything works.

It appears to be timed with the clutch switch. If the bike is running, and I begin to let the clutch lever out, in gear, the switch clicks and the sound cuts off.

Ok let's isolate this.
Bike is running in gear and clutch is out ( radio does not plays)
Bike is in Neutral clutch is out ( radio does play )
If you sit on the bike not running and play with clutch does the radio cut out...?
If this is all true , than the clutch switch is not a factor...
Check fuses ( I would replace them ) 1. 13. 10.
Check your kick stand switch
start there

1) True
2) True
3) Radio also works if bike is not running, regardless of gear or clutch.

All fuses have power.
Kick Stand is removed. Where would I find the switch?.

Maybe Diode in fuse box??

By the way, thanks for your help.
Looks like warranty thing.

Let me check mine for a second.
But Id take it to be a voltage thing.
Hit the starter everything but the starter should go out.
This way your getting full amps to the starter system.
Ok I now just checked mine. It works same as yours all go off when you hit the starter.
Seem a practical thing to me for it to do.

[MDGeorge]

Thanks Jay.
However, my issue is not the starter turning things off. I expect that.
The problem is that when I put it into gear, the radio turns off.

[John Luciano]

Just to be safe I would purchase news fuses and change them. The next thing according to my shop manual is the control module . It has the Diode . If you have time left on the warrantee take it to a dealer

I realized that after rereading this thread.
But since you had restated yourself..............................My bad for missing or miss reading.

I appreciate your input. Thanks.

If it were the side stand, would it not cut the ignition off?

That I could not answer having never ridden a 2 wheeled GW.
But every other bike Ive owned in say the last 15 years.
Kickstand down was a dead issue.
Many times Ive shut down my RoadStar just by lowering the kickstand.
As I have a keyless ignition. My own design on it.
All my 2 wheelers though have had a kickstand interlock in recent years.
They only make sense from a safety standpoint..

Can you unplug the clutch switch at the handlebars and see if your problem goes away?.To my knowledge the only action it does is disengage cruise control when running.Why that switch would have anything to do with the radio could be a wiring or short problem somewhere.
Knowing the answer would be interesting.

[SEABILL]

Wonder if the problem is associated with the mute circuit?

If you suspect the clutch switch, there could be a broken or pinched wire in the left handlebar assembly.

If I pull the two plugs from the clutch switch, then use a fuse to connect the two plugs to each other, everything works. ( I don't know about the cruise)I do get the dreaded yellow ENGINE light.
Just leaving the switch unplugged does not change the problem.

I will check the wire diagram and see what the 2 wires are for. The switch does work properly. ( bike won't start in gear unless u pull the clutch lever) right?

What is that other switch for ? Cruise works on engine revs to turn off. I think

[cavie]

It is not fuses. It is not loose connections. It is the kickstand switch doing it's job. Trike builders usually ty wrap the switch up to the frame with the button pushed in. Sounds like yours has come loose. look for the switch in the area where it would have been as a two wheeler.

[John Luciano]

I really think if it was the kick stand the whole bike would die not just the radio

[MDGeorge]

I asked a Honda tech what they thought.
Since the radio works in neutral, they suspect the side stand switch.

I have an appointment Friday Morning with the Honda dealer to check it out. The trike builder agreed to pay for any costs due to the trike build.
