My mower has been acting up for the last several lawn mowing sessions. Up until it finally failed to start the problem would clear up before I could trouble shoot and repair the problem. On the last occasion, I did go ahead and replace the solenoid. But that was just throwing a part at it.
When I started the trouble isolation, I had been unable to locate a wire diagram(I have found a wire diagram at this time). So I started at the solenoid. The large terminal from the battery has 12 volts. The small terminal did not receive any voltage when the ignition was turned to the start position.
So I traced that wire to the park brake switch. No voltage on either side of that switch. The next location turned out to be the left steering control lever switch. The switch is mounted in a location that is not readily accessible. So I unplugged the connector and tested for voltage there. And I did get voltage on the wire there. For testing purposes, I placed a jumper on the back side of the connector and plugged the connector back in place. My reason for this being. The connector is a four position connector. And has two circuits. I believe it has the circuit for start position on the steering control and the other circuit I do not know right now of its function. But I wanted to make sure it was connected.
After placing the jumper I still did not get any voltage to the small terminal at the solenoid. After verifying my jumper had continuity. I found that the brake switch on this circuit was also bad. It also was a four pole connector with two circuits. My circuit being open in the switch the other circuit was good. So I went ahead and placed a jumper on the back side of the connector on my circuit.
Now when the ignition is set in the start position 12 volts is measured at the small terminal on the solenoid. But the starter does not do anything. What could be the problem? I would think it should engage the starter if the solenoid was good.
Edit: I have a link to the owners manual. On page 15 is the wiring diagram. On the work so fat it has been correct for my mower. I will test the ground on the solenoid and read through the link you supplied. Thank you for the info so far.
