rear air shock warning light ?

Postby squirrel » Sat Oct 25, 2014 1:46 pm



just done 200 miles today some of the time the rear suspension warning light comes on for 1-2 minutes goes off for 30-40 miles then comes back on again some times for 30 seconds or longer then nothing for 100+ miles then starts coming on again. i've checked the pressure.hoses.wiring all looks very good.and the ride feels like normal any suggestions welcome.thanks

Add some air see if it stops..if not look for loose connection/ground.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

Looking at the same problem.
I haven't yet attacked the problem but, I believe it is a wiring problem rather then a shock problem.
I rebuilt an '82 and used a wiring harness from another bike I had. The "suspension light" was on on that bike as well. When I finally got the second bike finished, turned on the key and the light is on on this bike as well.
The shocks are at 45 pounds and have not leaked any air over the last week.
If this is a ground issue, where is the ground? I have only one wire conecting the shock sending unit to the wiring harness.
Courious that the light was on on both bikes, the only thing both bike have in common is the wiring harness.
Any suggestions before I dive head-long into this issue?

I pumped mine up to 50 psi so far the light has stayed off and the ride is very good

I'm starting to wonder if I have a bad switch on both bikes. Later this morning I'm going to ground the switch directlt to the battery ground to see if that makes a difference.

When I switched away from air ride rear shocks on my 1100, part of the instructions was to ground the wire going to the shocks, otherwise the red light will stay on all the time. I haven't looked any further into the wiring diagram, but you may have an open in the wiring harness somewhere, causing the light to light.

I grounded the switch to the battery and the light stayed on, I'll ground the harness to the frame and see if it goes out. If it does, then the switch is most likely bad, if it stays lit, a boat load of wire tracing is in my future.

OK guys, I am a little more then embarrassed...
As I indicated in my previous posts, I was having an issue with the rear suspension warning light staying lit even though there was sufficient air in the rear shocks, and the shocks were not leaking.
I will make this short.
Checked a few things, tried a few things but could not get the light to go out.
I have a tach that is squealing so I removed it to lube the bronze bushing, After removing the tach I saw the three Dash Lights sitting there, the ones I had just removed from the rear of the tach. I turned on the key, and all three lit up...I started the bike....(wait for it...) ONE OF THEM WENT OFF...
A quick look at the wiring diagram of my particular bike and guess what..the one that went off is the Rear Suspension idiot light!
Long story short, I had a dash light plugged into the rear of the tach in the rear suspension light hole. I let air out of the shocks and it lit up as it should, put in air and it went out..
It looks like I "Cried Wolf".
All fixed now. If you have a suspension light that won't go out, check it, make sure it is the suspension light and not a dash light.
I feel a little foolish!!

A mistake anyone could make. Thanks for owning up to it - I know it's tough to do - because I've owned up to many myself over the years! :)

I just replaced OEM's with Progressives and was wondering if there was a way to adjust this "low air pressure" switch. When I first put them on, I set pressure to 30psi and measured only 1 inch of sag. Rode great. Noticed the low pressure light would come on while riding, and then once stopped, it would go off. I raised pressure to 40 and the light stayed off. Bike seems to ride a little too stiff for me, but rides fine with a passenger. What I am hoping is to lower pressure to about 25 or so to soften the ride, or will the future miles make it "loosen up"? I really don't want to disable the switch if I can help it.
This website is GREAT! Thanks for any help.

Ha sw3dl1 !

Same problem and solution here. I noticed my red suspecniosn light on this morning. I had burned-out bulbs in my tach, replaced them yesterday. My "suspension light" is actually just a tach illumination light in the wrong hole. Glad I looked here before monkeying around with the pressure switch. Thanks for the share.
