Question about 1978 kawasaki Z 650

1 Answer

I have a Kawasaki KZ 650 that will not start. New battery, new coil packs, new plugs, new wireharness. When the starter button is depressed, it makes a sound like grinding, like teeth missing. I am unfamiliar with this bike so any help would be appreciated.

1977 kawasaki kz 650 no power or start.


It sounds like something may have shorted, come loose, or burned out.
Tracing where this is will take time and a multimeter to test all connections.

Bike won't start, nothing wrong with battery, just a clicking noise when ignition button is depressed


Hi, Justin it should be noted that in order to "PROPERLY" diagnosis any electric starter issue it is "IMPERATIVE" that you begin with a fully charged battery 12.5 volts or better and be able to pass a proper load test, and the usual suspects are:
1. Battery terminals have loose or corroded connections.
2. Battery cables faulty due corroded or broken internal wiring at the cable connector especially the "NEGATIVE" cable which needs to be checked at "BOTH" ends.
3. Battery voltage, must be 12.5 volts or better, voltage from the battery to the main circuit breaker to the ignition switch to the security/ignition fuse to the TSM/TSSM module to the engine stop/run switch to the starter button to the starter relay to the green wire that connects to the starter solenoid can not drop more than 1/2 volt of battery voltage.
4. With a voltmeter connected to the battery, the ignition switch in the on position, the kill switch in the run position, the starter button depressed, starter engagement should not bring voltage below 8-9 volts.
If a lower voltage is produced a proper battery load test should be performed with a load tester to validate battery integrity or battery replacement.
5. Faulty starter relay, check continuity.
6. Faulty starter solenoid, check contact plate and shoes for excessive electrical erosion/etching, refurbish as necessary or invert contact plate and use the virgin backside. Check contact shoes for being loose. Replace solenoid if the negative function is still a final outcome.
7. Faulty starter, bench test starter with a 12-volt battery if negative function check, decontaminate and undercut armature commutator segments as necessary, check segments with an ohmmeter probe each one and the segment next to it for shorts. Have the armature tested with a growler and field coils, and brush plate with an ohm-meter for opens, shorts or grounds. Replace brushes if less than .438" It is generally cheaper to overhaul/refurbish a starter motor than buying a new one.

Starter does not work but runs fine if push started (new battery)


Does the solenoid pull in when start is pressed?
If not check the supply and wiring from the start button to the solenoid.
If it does, check the relay supling the power to the main contact on the solenoid. (Battery feed).
Hope that helps

Electric starter won't work even with new battery


hi you need to check the starter solenoid it may have packed up put the ignition on and try bridging the two large terminals under the side panel with a jump lead the type for jump starting a car this should get the starter spinning if not you may need to remove the starter and check the brushes are ok on the motor

I have a 1980 kz1300 that starts up but mis fires any ideas?


Basic tune up. May need the carbs cleaned, new plugs/wires, and ignition system gone over, including points cleaning/replacement (if equipped) and checking for proper operation of alternator charge coil and rectifier/regulator.

Ensure battery is properly charged.

1995 kaw jet ski 750st push start button and it just clicks it was running great new battery and new plugs


Open the electronics box and jump the solenoid . If the starter works you have a bad solenoid. If you hold the starter button and tap on the starter, and the starter works , you need starter brushes. If the starter has burnt coils, has a shorted armature , or is wet inside, you need a new starter.
