Hi all, I've got an 89 GL1500, it was running like a champ. I shut it off and 2 days later when i went to start it i had no spark. I've already checked my ecu,kill switch, ohm readings on the pulse generators And coils and everything checks out. The battery is fully charged and never drops below 11.7 volts. I even tried jumping the solenoid. I'm at a loss. Any help is Greatly appreciated, thanks

If I am understanding correctly, you can crank the engine but it does not start and run, right?

The voltage at the ECM is important especially when cranking, it may be dropping before ECM and ignition coils.

Measure the voltage at the black/white wire at the C54 connector (near the ECM) or at the C57 connector (over the right fan) while cranking and when the connectors are connected.

Report the voltage you will measure, then we can continue.

Okay.. it'll probably be tomorrow. Its raining atm and the bike is under a cover outside. I don't have the luxury of a garage atm.

Okay, well i determined i had a bad battery , exchanged it and even with a new battery the voltage going to the coils (black wire white stripe) was well under 11 volts. It dropped as low as 10.1. Im adsuming the starter is worn out and drawing too many amps.

A lot of things may be causing that voltage drop, but with a bad battery it becomes obvious and starts creating problems. Bad, loose or corroded contacts of the fuses, relays, switches, connectors, aging wire harness, terminals of the battery, grounding points etc. will drop the voltage.

After checking those things listed above, if you still have the starting problem, you could try this modification that I have done on my bike.

I would try what Dave said in goldwingfacts.com before I would do any modifications to your bike.
Why add additional circuits when it can be done like this.......??

----------------------------------------------------------------------------

Engine will not start until the starter switch is released

Those who have GL1500's that won't start until releasing the start button can go into the right front side fairing and clean the C54 connector that feeds the pulse coils.

It carries both the 12 volt D C and the ground return.

Road dirt and condensation gets to it because it isn't waterproof. BTDT with our '96, and it fixed the problem, starts perfectly every time without having to release the button to fire.

The dirt/condensation layer bleeds enough of the 12 vdc coming to the coils off so that their firing voltage is below start levels.

The button release does provide a momentary spike that fires the bike up.

Those of you willing to go after this will be pleasantly surprised at the results.

See pages 3-0 and 12-3 in the Honda Electrical Troubleshooting Manual

It is just one of the connectors that I have mentioned in the previous post. But not the only one. I had answered his objection in that thread.

:D okay some good news :-) today I tried running a jumper wire from the battery to the black wire with the white stripe which I'm assuming is the hot wire for the coil and she fired right up. So I wired in a relay and it is starting every time now. Thank you all for all of your help it is nice to be able to bounce ideas around.
I'm attaching a couple pictures of the bike the first one is how far I had it tore down and I am still reassembling from. The second picture is me on the bike before I tore it down. Once again thank you all for all of your help and hopefully this thread will help somebody else in the future. God bless and keep the rubber side down

Something I just thought I should mention is that I picked the bike up for $300 and it's only got 66,800 miles on it it's been parked and stored since 2012 for the most part. I've put new tires and new brakes on it but I am having a difficult time getting the rear master cylinder out in order to rebuild it. As you see in the pictures above it really needs a paint job and it will be getting one eventually but it purrs like a kitten with the Mufflers on and when I got it to run today I did not have them on and it Roars like a lion. Obviously I plan on putting the quiet exhaust back on it and not running it with straight pipes. I don't think that would be very good on the engine to not have back pressure. I have also had to replace several other miscellaneous Parts as well. I probably have close to $1,000 in Parts into the bike at the moment. I put Shinko tires on it just due to the inexpensive aspect of them at the moment but I plan on putting metzler's on for the next set. I am having a difficult time finding a decent used rear rotor for the brakes though. I thought I had found one on eBay unfortunately it looks as if it is from a newer model because it is larger then the one that I had on there. Unfortunately the one that is on it is at 5.2 mm and thickness and will not pass local safety inspections here in Virginia. I am assuming that I will go ahead and just buy a brand new one but they are definitely not cheap. I have also noticed that you can use standard 9003 Automotive headlight bulbs and they are a lot brighter than the stock ones. One problem I do have right now though is my headlight adjuster is not working right it feels like something came loose and I am afraid I'm going to have to tear the entire fairing apart in order to figure out what it is. You guys would know better than I do if it is a common problem. Thanks again for all of your help

A rear rotor is available here for about $205

http://cyclemax.com/inc/sdetail/gl1500_ ... 58744/3344

The headlight adjuster mechanism should be accessible from behind the chrome or silver trim just below the windshield. Much easier to get to than taking the fairing apart, and the same parts that have to be removed to install those new headlight bulbs you reference.

It is good to hear you solved the starting problem. I just wanted to remind you something that you haven't mentioned about this modification.

Did you add a fuse on the hot wire coming from the battery as described in my modification? It is very important for safety, if you haven't done yet.

Yes, 2 female pressure connectors and a 10a blade fuse.
One thing im not sure of is exactly how to get the rear master cyl out. I pulled a couple screws but it looks like im gonna have to pull the exhaust equalizer out in order to remove the master.. my haynes manual is kinda vague

Personally I haven't done it, but this video gives a good idea about what to do.

Note that, to remove the collector box, you need to remove one of the exhaust pipes (right one is easier to remove) coming from the engine.

Okay,, update on my GoldThang
i got the brakes rebuilt and actually got her on the road, for 1 day, then she wouldnt start again. I exchanged the nEverstart batt from walmart for a new one, still no joy. I ordered a set of E3 plugs from O'Reiley's yesterday and they should be in today. My finances are limited or i would have just replaced the batt with an AGM this paycheck as well. The bike was running super rich and went through about 3+gallons on an 80 mile round trip to work. It also had a nasty dead spot in low rpms and seemed sluggish until it got up around 2k. I am hoping that all the problems stem from a need for plugs as i Did take them out while i had the plastic off and they were pretty nasty. I was tapped on cash or i would have just bought new ones then. Its about $15 for the Oem Ngk's and about $25 for the E3's. I am a firm believer in the old adage, you get what you pay for and i have seen Many positive reviews on the E3 plugs varying from no longer needing to choke the bike to start it to no flat spots in acceleration. I was considering looking for upgraded coils but wasnt sure if there Were any. I'll update more after i get the new plugs in. Btw i Do plan on getting the Agm batt next payday

Have you done a voltage leak test? Maybe something is draining out the battery.

It's a Walmart EverStart battery. One of the lead acid ones. It does not impress me but unfortunately I don't really have the extra money right now for another better one. I am planning on getting one of the AGM batteries from O'Reilly's next payday. I have a really nice Schumacher automatic digital charger that I keep on it when I'm not writing it so the battery stays fully charged.

I am still using the OEM battery without any issues. I had asked a question about leakage test. Did you do that, do you know how to do?

If you have a multimeter you can do it easily following the procedure in the previous post.

The purpose of this test is to find the current flow from the battery when everything is off. There should be a little amount of current (5mA) consumed by devices like clock, radio memory etc. If the current flow is more than 5mA, then there is a problem needs to be fixed.

Leak test was good, ground strap is good. Im ordering a new/used ecu wjen i get paid this fri. Hopefully thatll solve the issue

Make sure the battery is good, terminals are not loose, ICU connectors are connected firmly.

If you will order an ICU, be careful to order one for a 89 model. Other years will not work.

On your bike, engine will crank but not start when the kill switch is at OFF position. Make sure it is at RUN position.

I was planning on making sure it was an 89 ecu,,
And i have made sure the kill switch is in the run position

Sorry if I'm missing something....Is this still valid?
" okay some good news :-) today I tried running a jumper wire from the battery to the black wire with the white stripe which I'm assuming is the hot wire for the coil and she fired right up. "

If bypassing all the normal electric and applying power direct to the black/white wire (switched 12 volts) fires the bike up..(has spark)..replacing the module is mute.It works.
There's a few circuits involved in getting power to the coils/ecm module.

I ran the jumper wire a while back and she fired up.. now it doesnt work. Still no spark. Im really hoping the problem is with the ecu
