Installed an air horn and blew my rear suspension

Post by LDodge » Wed Jun 27, 2018 7:17 pm



I bought my '96 Goldwing back in November and set the rear air shocks at 60 psi. I checked it a bit later and it was still 60 psi so I forgot about it. Fast forward to 2 weeks ago....

I just installed a mini air horn and mounted the horn in the right fairing side vent (took a little cutting but it fit ;) ). I mounted the air compressor and relay switch in the locked dash compartment. I carefully drilled a hole through the duct under the compartment to run wires / air hose; I had my hand under the duct so I wouldn't go to far through. I tested the horn and it is LOUD :D YIPPIE all is good.

Then I had a thought that I better check the air compressor buttons just to make sure everything was still good (I have really big hands and there wasn't a lot of space to wiggle wires / hose). When I pushed the compressor button and up button, the compressor came on and the digital display read 60 ..., 59, 58, 57, 56 ------ RELEASE the buttons quickly. I came back the next day to try it again, the compressor came on and display read 39, 38, 37, again release the buttons. Tested again and is sitting at 30.

So my question is this... are there any air hoses in the front of the bike behind the air compressor buttons or is it just an electrical switch? Would it be possible I accidentally disconnected something (again big hands and Tupperware bikes don't mix well) or is something else going on and I am just now finding this out co-incidentally? Should I disassemble the front fairing first or take of the rear truck to get to the compressor?

On a side note, there is an LED strip on the vent grill and when I took the grill off the wires and LED strip sadly parted company. How do I reunite those itty bitty wires with the LED strip? Are there mini wire strippers? Should I solder them or is there a better way?

Thank you much
Lawrence

As to "side note" …. usually very tiny wires are easily stripped between finger nails . Is there access to a place to solder them remaining on the strip?

Don't the buttons just operate the electric valves?


Any hoses in that area may be only for the carbs not the suspension.
Just guessing.

"Installed an air horn and blew my rear suspension"

Just re-read thread, that was a big horn.

I've not had cause to get that intimate with our 1500's air buttons but my 1200 has some buttuns that simply direct air to different lines. You maybe right.

Yes you are right. theres no hoses in the area for the compressor. just the switch controls.
you may have dislodged a wire or plug to the control unit

Yeah and he also used a separate compressor for the horns.

Correct, unlike GL1100 and GL1200 (which have switches that directly, mechanically actuate valves), the GL1500 has switches that are electrical, and are used to actuate solenoid-actuated valves in the rear of the bike.

There are air hoses and solenoid-actuated air valves in the panel directly behind those buttons, but those are part of the PAIR (Pulse Secondary Air Injection) system, and lead to the exhaust manifold. They are used to inject air into the exhaust manifold to help burn off unburned hydrocarbons (primarily during deceleration) to reduce emissions.

Well I finally found time to look into the problem. I took the locked dash box off and look underneath; nothing was disconnected and the P.Check / Inflate would get the pressure up to only about 20. I took off the seat (was trying hard NOT to have to remove the left saddlebag --> BIG pain). The compressor was kicking in; though it sounded like an air release after I released the switch. I looked at the sight window but couldn't see anything. Then I disconnected the hose to the air shock on the right side and hit the P.Check / Inflate buttons and a good amount of gunky brown liquid (kind of oily) squirted out. I held my finger on the hose end but again could only get up to 20 on the digital dash display
I took the Schrader valve off the auxiliary hose (never had any luck with those blowing up a tire anyways) and screwed it into the air shock, pumped it up to my preferred 50 p.s.i. and did some other maintenance, checked it, still at 50. Then I dropped it as hard as I could off the center stand and it still held 50 p.s.i.. Took it for a test drive and could DEFINITELY fell a difference from the 20 p.s.i. it was running at to the 50 p.s.i. :)
So I am thinking the desiccant is probably soaked and need to be dried out. Does anyone have any other thoughts on what might be going on that it would not pump up past 20 p.s.i?
thanks for your input -- ALWAYS greatly appreciated.

Bad dessicant won't affect the pressure, all it does is draw moisture out of the air before it is pumped into your suspension. And you just proved that the compressor is operating correctly due to the fact that it pumped up your shock to 50 psi.

Sounds like you may have a leak in the hose going to the air shock, perhaps?

Let me restate - I pumped up my shock with an external air compressor.
So moisture in my internal compressor won't affect high much it can put out?
I will look at the hoses when I lift my trunk assembly to change my pads :D
Thanks again for all your help

No, the reason for the dessicant is to remove the moisture from the air so you don't pump moisture into your shocks and rust them from the inside. The pump works equally well with and without the dessicant.
