96 gl1500 stalling issue

Postby kyle1971 » Sat Mar 29, 2014 6:49 pm



Got a 1996 GL1500 with approx 33,000 Miles on it and about a month ago it starting having this strange stalling issue. I started noticing that when i would use my turn signal every 5th or so time it woudl cause it to jump and at first i wasnt sure what was going on but then realize it was stalling and starting back up while driving. It then started to stall while i was idling but would start right back up. There is no pattern to the stalling just happens randomly. Some days i can drive to work for an hour and it will do it once at the end of the hour trip and other days i will start to work and get to the gas station five minutes later and it dies while idling. Ok so know what i have done since the problem started. I installed an high output amp, replaced the bank angle sensor and just this weekend installed new pulse generators. I am stumped to what could be causing this and looking for advice on where to continue looking.

Is the tank less than half full? If so, there could be some problem with the fuel delivery - aka petcock. Have a look at the Q&A in the previous post about "Automatic Fuel..."

Just a though have you looked at the dog-bone fuse for any cracks ? And if you put the high out put amp in did you double up on the dog bone fuse? I had my 96 keep cutting out on me while driving but it was due to the gas cap being clogged up and causing it to not be able to pump fuel.I would also check the kill switch for intermittent operation,hope you can get her fixed with out to much trouble.

Also try jiggling the kill switch to see if it might be dirty. If it is suddenly missing like that, it's more likely electrical than fuel related.

checked dogbone fuse and all looks good there. took apart my kill switch and couldnt see any issue with the connections. Jiggled them while bike was running and didnt see any issues. I am 99.9 % sure its an electrical issue. I have had fuel related issues in the past and the bike doesnt sputter out like its fuel starved it just cuts out like there is a short somewhere.

not sure if this will help to diagnose the problem but when it does stall out both of my turn signal lights will come on and stay on until i start the bike back up.

Drove bike to work this morning and was having same issue with bike cutting out when using my turn signals but this time i noticed that some of the lights on my dash did not work as well. After driving for about 30 minutes they came back on.

Yes, this definitely sounds like a grounding issue. Some critical engine circuit (ignition? ECU?) has lost its ground, and is instead finding its ground through the turn signals. When you turn the turn signals on, that ground is lost, and the engine quits. I'll have to have a closer look at the schematic to see just how/if this is possible however.

I'm not sure bout yours but my 88 has a peculiar ground system.
On the right side harness below the gas cap area there is a bundle of green ground wires in a plug.theres a shorting cap on it and a common ground to the frame just below it.
I have seen this block have corroded/burnt wires in it.

Yes the grounding block would be a good place to look. There is one on both sides of the bike buried in the wiring harness. They have about a dozen green ground wires each. Take the upper fairing parts off and look about where your knees would be. You will have to unwrap some of the wiring harness to find them.
Here is a link to a thread in another forum that tells how to fix this.

i have torn my bike apart and for the life of me cannot find this common ground that he shows. and of course i cannot get the bike to stall when im working on it. I have wires every where right now and by far not an electrician so worried i might be getting in over my head. I have inspected the grounds that i can find and dont see any major issues.

I had stalling issues with my 96 last year. After doing "this and that" local mech checked the fuel filter. It was clogged BIG TIME. Replaced fuel filter no more stalling issues.

The common ground he shows in that picture is buried inside the wiring harness. You have to start peeling the electrical tape off the harness in order to expose it - you can't just see it by looking around.

i did remove the electrical tape on the left side all the way up to the plugs that are above the fan and doug through the wires and could not locate the common ground.

I do not think your stalling issues are ign related. A temporary cessation of ign will 99% of the time cause a backfire. Ask anyone who has ever hit their kill sw off by accident while riding and turned back on, boom. :D

Yeah, you got electrical issues and I can almost guarantee that if you were to slip clutch and stall intentionally the turn signal indicators would glow then too. No connection to causing a stall.

With only 33k on the clock my money would be on fuel/carb issues.

it does back fire occassionaly. I know i currently have an idle surge and was planning on pulling the carbs in the future to repace the vacuum hoses. This is a very frustrating issue because of course when i need it to stall i cant recreate the problem.

the only confusing part about it being the carbs would be me using the turn signals and it causing the bike to stall and then the issue with me losing lights on my dash. i would not think a carb issue would cause my lights to shut off on dash and the blinkers to kill my engine.

Yeah, I think there's no question that it is electrical in nature. It's just a matter of finding the source of it. Sorry, I've been buried the last couple of days and haven't had time to look at the schematic. Virgil, maybe you might have a look?

im just going to put it out there that i typically dont have a clue how to read the schematics so any helpful info on it would be greatly appreciated.

So the bike has never stalled except the moment you put the turn signals on?

The reason why you might not be finding that ground connector is because the Interstate has much less wiring and the harness is most likely different.

Getting back to the original stall problem, you are in way over your head now tearing this and that apart, replacing this and that which is not the way to go.

Best advice is to take one thing at a time, known carb troubles with surging and poor idle, fix it.
Dash light/turn signal problems, fix that, without trying to connect dots that this is causing that and in the meantime bypassing what you think is irrelevant.
Stay focused and committed to one particular repair at a time and in the end all pieces of the puzzle just might fall together.

Diagnosis has to be taken in a logical progression working from one system to another.

99% of the time there is no one magic part that someone over the Internet can point you to. The only time a mechanic should blindly replace a part is on a recall/campaign program from the manufacturer, everything else is done through diagnosis.
