1994 GL 1500 Cruise faulty

Postby Andydu » Tue Feb 28, 2012 6:05 am



Hi Guy's

Is there somebody out there that is maybe able to help me solve the problem with my bikes cruise control. I have checked all the switches and they all seem to be fine. I did the tests by disconnecting the electrical plug under the seat and using a multi meter measured the various swithes for continuity and/or resistance. All measured fine except for 7.5 ohms on the 4th gear switch instead of 0 ohms and 109 ohms on the Solenoid valve for the Relief valve and Vent valve instead of 82 ohms. Are these differences critical and if so how do I solve them? Somethig else that I have found is that if I set the cruise control and then hold the resume button the bike travels at a constant speed. If I let the resume button go the bike slows down. When I press the set button the light on the display comes on but nothing else happens.

The diagnostic procedures for finding problems with the cruise control are quite lengthy, and are detailed in the Honda service manual. Do you have a copy of that manual?

I've been sitting here reading this post for 2 days now and I had a thought..... :geek:
Ouch...that hurt... :lol:
The one thing that sticks out is holding the button will hold the cruise.......
This sounds more like a vacuum problem than a obscure electronic anomaly.
I'd really be replacing the 18 year old hoses and maybe check the one way valve that feeds the vacuum accumulator.Page 4-78 in the manual.

Sorry,it just seems like 2 days.I just read it this morning.Also did you clean or replace the filter on the valve assembly?Mine had deteriorated.I cut a piece of foam from a small engine air cleaner to fit mine.

Hi Guy's

Thank you for coming back to me. No I have not got a service manual for the bike as I bought it a week ago and got no documentation with the bike. The tests I have done have been done from documentation I found on this site. I made sure that there is 12 volts DC going to the unit by putting the red test probe on pin 17 and the black probe on the frame. I then switched the ignition on and pressed the cruise "ON" switch. I have tested the Throttel switch and the Rear brake switch, Front brake Switch, Clutch switch, the 4th and 5th Gear switches. I got continuity on all the switches. I got a reading of 7.5 ohms on the 4th Gear and 0.5 ohms on the 5th Gear. I also tested the solenoid valve system. I got 89 ohms for the solenoid valves for the Vent and Vacuuum valve. I got 89 ohms for the solenoid valves for the Relief valve and Vacuuum valve. I got 109 ohms for the solenoid valves for the Relief valve and Vent valve. I did not test the Vacuum system as I am not sure on how to do it. It is my first Gold Wing and I am trying my best to solve the problem. For many years Gold wings were only brought into South Africa as grey imports and as such the local Honda dealers have had very limited exposure to them. I have also got a 1300 Pan European which gets serviced by the local Honda agent. Virgilmobile you have got me worried with your reponse as it seems that if I have got a vacum problem it is going to be a huge project and very costly. I realy do not know where to start.

Andydu: You have a PM. Concerning the Honda manual.

Don't worry.I would suggest pulling the covers needed to access the left side.That's where all the vacuum lines are.
It's common that vacuum lines either get hard and no longer seal at the joint or in this case,I found the hose connected to the left manifold,at the sharp 90* bend had weekend and collapsed.
The very first thing is to check that hose on the manifold.I've marked it on the pix in blue.
On mine it was real weak so I just cut a inch or so off it and stuck it back on.
Other hoses to consider are also circled.
The "one way" is a check valve.You could remove it.It should allow air to blow through one way but restrict it the other.
The valve allows the accumulator to build up a vacuum reserve to operate the cruise unit.
If the valve is leaking badly or any of the lines don't seal it just won't work.
This also includes the control valve assembly.When operated they open and close to allow the vacuum to increase or decrease.So for example,if the vent valve is contaminated and stuck open,the cruise will never hold.
Just try the easy stuff first.Cut a inch off the ends of the hoses (if they will still reach) and put them back on.
You really don't need special tools.Either a valve works or not.If not then flush it out and try again.
On my 88,I replaced the vacuum lines that were really bad.The whole job took a day or two.I just removed one hose at a time,cut a new one and replaced it.The hoses cost 85 cents a foot here so I just bought 5 foot while I was there.

Thanks for that Virgil.

I'm looking at a '94 SE this weekend that the owner states has never had cruise work for the 3 years he has owned it. The lights all work on the dash per the manual though.

It seems that the electrical system is pretty robust . So far on mine,I've just found the vacuum hoses have caused a good variety of problems,from the cruise to the way the engine runs and idles.
Even those pesky hoses under the carb assembly thats under the rubber mat.

HI andydu'
IF you have a import from Japan, the Cruise will not work above 80 KPH that is their spec.
