I have Hanmar9 . I cannot get it to start. The battery is fully charged,but when you push the starter control all it does is click like it is not fullly connected. Then it will run the battery down it you keep trying to start it. Does any one know what th problem could be?

 

Welcome to the forums.
It sounds like a bad relay to me but I'm not that good at electronics.
Expert Lynn will help I'm sure.

 

There are several possibilities here. Lets do a couple of tests to isolate the more common ones:

1) Follow the fat red wire from the battery positive terminal to a screw post on the starter solenoid. Follow the fat red wire from the other screw post on the starter solenoid down to the starter motor. The solenoid is the thing that goes "click" when you press the start button, right? Keep those two screw posts in mind...

Important: Set the parking brake and make sure your quad is in neutral before proceeding with the next steps. You are about to bypass the safety interlocks which prevent the quad from starting in gear with no brakes applied.

Turn on the ignition and set all kill switches to the run position. Take a screwdriver and short the two screw posts on the starter solenoid identified above with the screwdriver shank. Some sparking is OK. Starter motors draw a fair amount of current.

Does the start turn? Does the quad start?

The starter solenoid is just a remote operated switch. When you apply 12 volts across the two *small* wires on the solenoid an internal coil generates a magnetic field which sucks down a steel plate which shorts the two big screw post together - just like you did with your screwdriver - and connects the battery directly to the starter motor. If the starter turns with the screwdriver short, and not when the solenoid goes "click" then your solenoid is bad. BTW, the fact that is goes "click" says that the small wires side of the solenoid circuitry is working. The click comes from the steel plate inside being sucked down but it isn't managing to short the two screw posts together.

2) Take a pair of automotive battery jumper cables and jump the quad battery to your car battery. Be sure to get the polarity right (plus to plus, and minus to minus).

Try to start the quad. Does the starter motor turn now?

Sometimes old and worn out batteries can read fully charged, but they cannot put out enough current to crank the engine. There is enough current to engage the solenoid (it goes click) but the battery voltage then collapses under the starter motor load and the starter doesn't turn. Jumping the sick quad battery to your car will allow the starter to turn normally if the battery is the problem.

If neither of the above solves your problem then get yourself a meter and we can delve in deeper. The other possibilities are bad starter, bad connections in the wiring, and an engine that is frozen up. These are less likely then the above problems.
