I will disconnect the grounds, clean them and reconnect them...see if that helps. You know, the owner told me that she ran over her trickle charge near the back of the mower prior to me getting the mower. However, she said the mower ran after that...I'll check under the mower, see if I can locate any problems...
This is supposed to have a three solenoid and not a four terminal. But four terminal (two large and two small) solenoids are usable if you connect one of the small terminals permanently to ground. On the three terminal version this is internally to the mounting bracket which is then mounted to the metal chassis [frame] for the ground return.

Is this at the solenoid or the ignition switch. If at the ignition this is the magneto kill circuit which is ground in the ignition off to kill the spark. Otherwise if at the solenoid then you have a grounding problem. The solenoid ground should be hardwired to chassis ground.
