no spark

Postby schmitty52 » Sun Aug 02, 2015 8:48 pm



Let me say that my 1988 gl1500 was running great, no problems. I came home from work back it into my garage, went to leave the next morning bike would not start, cranks over as normal. I can smell fuel checked for spark there is non. What are my next thing to look for. I would like to see if I can figure it out on my own. I have checked the fuses in the main box. I have also checked the kill switch and moved the kick stand up and down. What's next before I call a repair shop.

Even tho it cranks,there can be no spark if the battery is poor.The ignition module must have above 10 volts to get it to work.First thing would be to charge the battery,load test it or measure the volts while cranking.
There are other Saftey circuits that can kill the ignition too,like the bank angle sensor,main relay,etc.
You'd have to pull the side cover off to get to the ignition module to test for those voltages.If you do get to the module,12 volts should be on a black/white wire feeding the module.Its the main feed.

Also,checking the kill switch position is ok,you can also locate that black/white wire leaving the switch...probe it for the 12 volts.

Yep. The battery is very likely your prime suspect. GL1500's are very well known for this - if the battery gets a tad old, there will be enough juice to a) spin the motor; b) fire the ignition; but c) not both at the same time.

One test is to see if, on occasion, the bike will suddenly fire up an instant AFTER you release the starter button. During that brief instant, the engine hasn't stopped spinning yet & suddenly there's enough juice to fire the ignition.

Mine did exactly this (although it only did the insta-start thing once in many tries...but it proved my battery was defunct).

The battery in a GL1500 has to do an enormous amount of work, and it's all packaged in a very small case. The standard-style batteries don't last all that long under these conditions and, if you have the original alternator (which was rather marginal, even when new), charging problems are inevitable.

To permanently cure the problem, I replaced both the battery (GET AN AGM-TYPE!!) and the alternator (with a 95-amp aftermarket one - I got one from LActrical on Amazon - cheap, simple to change, and powerful!!). Charging problems are gone. The new alt puts out more amps at idle than the OEM one did at maximum, so my bike's "electrical budget" is virtually unlimited.
