I have a 1980 KZ440A and I am having a problem starting it, I had no problem with it starting since I owned it. Now I press the button and it clicks, plenty of power and I can push start it no prob but it just clicks. I also hear the click from the solenoid when pressing the button. Replaced the starter but still doing it, please any help would be appreciated. Scott

 

Flat battery

 

did you test the starter relay?
Welcome to KF

 

Thank you for the reply's. I don't think its a flat battery, it was tested and I have had it on a trickle charger. I haven't tested the relay and I am not sure hoe to do that, any insight would be very much appreciated. Thank you, Scott

 

I will have to move over to the Win puter in order to scan info that may be pertinent. Even though it is of a KZ 305. Not sure if it will help, but will throw it out there for you to see if it works or not.

The gist: " Disconnect the starter motor lead from the starter relay and connect an ohmmeter set to the X 1 ohm range across the relay terminals. Turn on the ignition switch, push the starter button, and see if the meter reads zero ohms. If the relay makes a single clicking sound and the meter reads zero, the relay is good. If the relay clicks but the meter does not read zero, the relay is defective and must be replaced. If the relay does not click at all, disconnect the other two leads (black and yellow/red) in the right side cover, and measure the resistance across them. If the resistance is not about 4 ohms, the relay is defective. However, if there is not 4 ohms resistance, the rela may be good; check that there is actual voltage to the relay before deciding that the relay is defective."
