Starter Diagnosis

Continuing the saga of my J model no start. I've tested the solenoid and all the switches and everything tests OK. Removed the sprocket cover, took off the hot wire to the starter, cleaned everything up, put the sprocket cover back on (for the clutch switch), but I still only get a clicking solenoid. Need to confirm my next step. Can I run jumpers (negative to bike ground and positive to the starter) to make sure my starter is bad (before ripping everything apart)? I would guess I need not worry about the clutch switch (or any others for that matter) if I jump it directly. I think the starter is bad, but just wanted to make sure. Your expertise is appreciated. Thanks.

As long as the car engine is NOT RUNNING, the battery can be used as a power source for your jumping need.

Something about voltage/current variations will affect the bikes electrical system.

Has the battery been load tested to determine if it's good?

Actually have a new battery in it Mike. May just use the old one to jump it with as it probably still is OK (although a couple of years old). Appreciate your help.

I can't remember if I've sent this to you before:

Starter Solenoid/Motor Checkout Procedure

Some simple steps to determine what is working and what's not:

1.Fully charge and test the battery(most bike shops can load test the battery, and then use a floating ball hydrometer to check specific gravity in the charged cells).

2.Clean all battery terminals of corrosion.

3.Tighten all starting related connections(Positive RED(+) battery terminal, Negative BLACK(-)terminal) and from the terminal to the engine case. All connections must be clean and tight.

4.Clean the cable from the starter solenoid to the starter motor.

5.Clean and check the "bullet connectors" going to the coil side of the starter solenoid.

6.Try again to start the bike, keep in mind some Kawasaki’s have a clutch interlock to prevent cranking the engine while it’s in gear, so the clutch lever must be squeezed.

7.If no luck, go to step #8

8.Wearing eye protection, bridge with pliers or a screwdriver the two heavy duty(large)terminals on the solenoid. If the bike cranks, your solenoid may be bad.

9. If the starter won’t turn over, one of several things has happened; The starter motor has seized due to brushes binding up, lack of lubrication in the bushings of the motor, the battery is weak , the engine has seized or it could be a combination of any of the above. Some websites for starter motor rebuild kits are:

10.The dealer may want $$$ for a new solenoid, but take your old one along and visit the nearest riding lawn mower shop. They have solenoids for about $15 that with a little work will fit. Be aware that the new solenoid from the lawn mower shop may require a ground wire for it to work.

11. I’d recommend upgrading from the existing battery cables to at least 6 gauge welding cables.
They are available in two colors(RED and BLACK) have more flexibility due to being constructed with finer conductors, and will fit in tighter areas.

12. The welding cable is sold by the foot, so take careful measurements or bring your old cables along. Most battery shops might be able to supply the cable too, so call to find out. The battery shop should be able to crimp/swage on the end of the welding cable the terminal ends or lugs using either a dedicated crimping machine or a tool that looks like a bolt cutter that has special dies to terminate the cable.
