no spark

i had my 79 kz1000 over in a friends garage,for winter.when i took it over i had spark,now no spark.also i took off two spark plug wires off right side coils forgot where the wires went on coils.stupid,any help thankful.

Probablt too much information here, but keep it for future reference:

Ignition Coil Primary And Secondary Wiring

Ignition coils on the 80’s Kz1000,Kz1100’s and Gpz1100’s are wired the same, that is as you sit on the bike, the LEFT ignition coil primary(small wires) are two wires, RED and BLACK. The secondary (or sparkplug wires) got to #1 and #4 sparkplugs.

The cylinders are numbered left to right as you sit on the seat; #1,#2,#3, and #4.

For the RIGHT ignition coil, the primary wires, again are two wires, RED and GREEN, with the secondary going to #2 and #3.

The RED wire gets it’s voltage from the run/stop switch on the right handlebar switch pod.

The BLACK and GREEN wires connect to the IC Igniter(if the bike has the Kawasaki supplied electronic ignition) it actually gives the coils their grounds to fire the sparkplugs.

Primary(small wires) side of the coils will read between 1.8 to 3.0 ohms.

Secondary(sparkplug wire ports)side of the coil will read between 10.4K to 15.6K ohms.

Keep in mind that the smaller 4’s (650 & 750) may have the wiring reversed, that is the RIGHT coil primary will be two wires, RED and BLACK with the secondary(sparkplugs) going to #1 and #4.

The LEFT coils primary wiring would be again two wires, RED and GREEN, with the secondary(sparkplugs) going to #2 and #3.

These engines have what is known as a “Wasted Spark” that is, a sparkplug will fire during an exhaust stroke. It does no damage and many other motorcycle engines have this design.

thank you

From right side coil, one spark plug wire attaches to #2 plug, and the other spark plug wire attaches to #3 plug. Either inside plug wire may connect to either right side coil output.

From left side coil, one spark plug wire attaches to #1 plug, and the other spark plug wire attaches to #4 plug. Either outside plug wire may connect to either left side coil output.

In other words, the right side coil fires the two inside spark plugs. And the left side coil fires the two outside spark plugs.

Good Fortune!

thanks guys ,the wire i was trying to check spark on wasn't on coil good.i dont like how the dayn coils,dont have mush room for wires
