1985 gl1200 ltd just cut out and died

Postby iamwill » Thu Jun 02, 2011 9:54 pm



My 1985 gl1200 cut off on me yesterday and still will not crank. Sounded and acted like it ran out of gas or lost fire. what size is the spark plug socket? or does it have to be a special one? When it died out it was running at about 50 and would not crank back up it kinda would then it wouldnt take any throttle at all I noticed it heated a little bit during earlier riding. I have only had this bike for a little over a month, never owned a wing before. Had new oil filter on it and was told oil was just changed, never looked at the oil I checked it for the first time the other day and it was over a quart low according to the dipstick. Also I had put a bottle of lucas fuel injector cleaner in it I had been putting 87 octane in it like an idiot.

Spark,gas and compression are all needed to fire a engine.One of them quit.
Easiest thing to check first is the FUSES for the ignition and fuel,then spark.Pull 1 plug wire and put on a old plug,lay it on the block,crank it over to check for spark.If none,check the kill switch.If the spark is OK then it must of run out of gas or has a fuel delivery problem(pump quit).I doubt you have a compression issue,If it broke a timing belt it would have made a ugly noise.

CHECK THE CONNECTER NEXT TO THE BATTERY, ITS VERY COMMON FOR THAT CONNECTOR TO BURN-MELT AND CAUSE THE BIKE TO QUIT. IF THAT IS YOUR PROBLEM THEN JUST CUT IT OFF AND HARD WIRE IT BACK TOGETHER AND IT SHOULD BE FINE.

I was told that since they started putting ethanol in gas that they have had a huge increase in fuel pumps going bad. Evidently the ethanol is eating the rubber inside. My bike just did the same thing and it was the pick up coil. Hope this helps.

today cranked up and all gauges on the digital dash went haywire then I cut it off wouldnt do anything at all after that when pushing on the starter button. Wait it gets stranger, then about an hour later it spun the starter with ease but was not firing obviously cuz it didnt crank. Ignition module could do this?

Just a guess here...Replace the Dog Bone fuse..Known fail point causing intermittent everything.It's on the starter relay,under the cover.

Hey Guys, I also have a '85 GL 1200 Interstate. It starts, runs great for about 3 - 5 min.s then dies (no spark at all) after setting a couple days, it does the same thing. Can anyone point me in the right direction? Please help :shock:

Is there power getting to the coils? If the spark is going away, you need to start at the coils and go backwards towards the battery until you DO find power. That at least will give you an idea of where the problem is occurring.

Pull the cover off the battery,there is a white connector next to the battery.If it is not already melted then pull it apart and see if it looks Burnt. If it is melted or burnt just cut it out and HARD WIRE it. 85 - 87 Wings are famous for this problem. Good Luck

Have power going to the coils. When cold, it starts, and runs great (for only 3 - 5 mins) then dies. NO SPARK, but still power to the coils. Replaced the twin coil pack, and sparkplug wires, does the same thing. Seems like something heats up, then shuts down. could it be the C D I pack, or a reley somewhere?

Also, the (dogbone) fuse your refering to, is on the starter siliniod, correct? I've also replaced that with an after market one from the Dealership. It has a (Blade) fuse instead. Also has a brand new starter put on 3 weeks ago. I do APPRECIATE all the help & info i can get. Thanks Guys! *Need to Ride* in Sunny central Florida

That's the one. Good replacing it with a blade fuse, it's a safe bet against future problems!

Guess my question is . . could a transister, or diod in the CDI be heating up, and shutting it down? I take it the paulse generator is good since it starts and runs. Any other ideas, or troubleshooting on this situation would help. And if so . . . do they make an after market CDI, since Honda no longer makes them, or would i have to try and pick up a used one off e-bay or a salvage yard? Or maybe a hidden reley somewhere i don't know about?

Yes the "CDI" can thermal fail.No aftermarket that I know of.It's a special design due to the vacuum sensor and gear shift input for ignition timing.
Here's a few pix that may help to troubleshoot.
Assume nothing.Please don't guess that something is OK because it does start up.I've gotten caught by just a intermittent corroded connector.You'll need a volt meter/ohm meter.

I would proceed in this way
1. measure the resistance of the pulse coils at the IGNITION module.This is your reference.A corroded plug near the battery can kill the ignition.
2.attach the volt meter to the black/white wire at the ignition module using it's green ground wire.
3.turn on the key and look for 12 volts on the bk/wh wire.DON"T START THE BIKE YET
4.measure the volts on yellow/blue and blue/yellow wires.This is the output to the coils.It may have from 8-12 volts on it.*** only measure these wires with the bike NOT running****
5.start the bike and look at the volts on the bk/wh wire on the module(12-14 volts DC)
****DON'T measure the Y/B , B/Y wires when running..300-400 volts there.****
6.When the bike dies,verify the module bk/wh wire still has the 12 volts.
7. leave the key on (bike dead) ,remeasure the yellow/blue and blue/yellow wires.to see if the coils opened up.(no volts)
8.If the module has 12 volts and y/b b/w wires have volts,shut off the key and measure the pulse coil wires. If the pulse coil resistance is near the same,the ignition module must be at fault.

At that point you could pull the module and replace it or see if it can be repaired.Sometimes a cold solder connection can be found if the PC board can be accessed.

Thanks for the info. I Checked the voltage as you discribed, have voltage BK/W-GR, and also BL-Y, AND Y-BL befor starting. Started just fine . . then again died after 3 - 5 mins. Rechecked the voltage on all wires discribed, and were still hot. Turned off the ignition to check the pulse generater. Checked the 3 wire connector infront of the battery, and it was (melted) so straight wired them. Started to rain, so didn't get to check the resistiance (ohlms) of the P/G. After the Bike died, i noticed the rectifier was hot, (is it supposed to be)?

Yes it must dissipate unneeded energy not used to charge the battery.
The 3 yellow wires are from the stator not the pulse generator,but repairing them was a good thing.
The PG plug is next to that one and has 4 wires in it.

I usually test the PG at the ignition control module.This also checks continuity in the plug next to the battery.Don't get worried if the OHMS do not match exactly to the book.Were looking for a drastic change here.

So up to this point you verified that the coils still had power through them when it died.That's good.One part eliminated as the cause.
I assume that the battery had enough power to still run the bike???
You did say the wires were melted and repaired.Battery not charging??
Did you by chance have to jump it off to start it?
A very weak battery and a failed charging system with the 10 amp draw while running can lower the volts enough to kill the ignition.
I suspect the module would start to die when the volts drops below 9 volts or so.I've never checked.
While it's running the next time ,measure the volts on the battery.It really needs to stay above 12 volts.You may need to bump up the idle to 1500 rpm to test it.

Keep at it.Your testing and eyesight for detail is good. :)

Thank you again. The battery seemed to be charging fine (before hard wiring the three yellow wires) today i will check the pulse generator resistance to see the reading. Will let you know what i find. The pulse generator at the battery location . . does it have a reley attached? And if so, could that be heating up and shutting it down?

No relays involved in the system at all.4 wires come from the back of the engine and plug into the harness to the left of the battery.They exit the harness and plug into the ignition module.
This is why I recommend testing the P/C at the module first.If you disturb the plug and it happens to be intermittent,you may fix the problem temporally.
Testing before and after will verify a good or bad wiring or P/C problem at the module.
If it should go high resistance at the module,then test it at the plug to split the system.Either wiring or P/C.
Does this make sense?Its split the system to determine which half the part is bad.It's just it has 6 parts that could fail.So it's divide and eliminate. :geek:

Well, here goes . . I retested every thing again as yesterday, (same results) All wires hot, bike started, then died after 3 mins. Cheched the pulse generator from engine (low resistance between WH/Y & Y, but no resistance between WH/BL & BL) The pulse generator on my bike is in the front of the engine, behind the timing cover, and plugs in to the left of the CDI pack bracket. Local Dealer said its available at $177.00, but will need to order it. Thinking of just selling it, and getting something differant. :(

I'll regroup .It sounds like the crank angle sensor is opening up.I've never seen one,but it should be just a coil of wire. Maybe repairable?

This may help.I've heard that the crank angle sensor may be intermittent and kill the whole ignition.Ohm it out.
