1978 gl1000 not getting spark

Post by 98.cr250 »



I have just recently purchased a 1978 gl1000, and it came with a dyno S ignition, but it didn’t get any spark. So I tracked down the original points for it thinking those would fix the problem but theres still no spark. I checked the power to the coils, the kill switch and the points and they all had power. Even the spark plugs had power going to them. I’ve never worked on these bikes before so I don’t know whats wrong. Thankyou in advance to anyone that responds.

What points? You shouldn't have any with a Dyna S. Did you remove the Dyna and convert back to points?
Did you follow the stock Honda wiring diagram and use the correct ballast resistor and coils? Those are often changed when going to electronic ignition.
This is a wasted spark system. Be sure you understand how that works as the coils are not grounded like a traditional distributor based ignition. Two plugs fire at once and the power is split between them.

Sorry for the misunderstanding but I meant I tracked down the original points and Im using those currently.

Points are pretty drop dead simple. You should be able to wire those up and get a spark. Maybe start by not using any factory wiring and just coming right off the battery with jump wires. Battery to ballast to coils, then to the points and condenser to ground. You don't even need to spin the motor over, just operate the points manually. Once you have confirmed you have spark, you will know all the components are good and can check over the wiring. Unfortunately, tons of GW owners do really poor wiring repairs and modifications. Then if by some luck it actually runs, they pat themselves on the back and ride off into the sunset.
