89 Gl1500 no spark

Post by DarrellFields » Fri Aug 11, 2017 2:59 pm



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.
