I can relate to your frustrations Mike, Sometimes electrical problems can be a bear to sort out...... You said you lost the click when you raised the seat, Un-plug the seat safety switch and put a short jumper wire across the connectors inside the plug. Make sure the parking brake is applied and both joysticks are out in neutral position. Now try to start it, Does it ? Did you re-gain the click ? You said you cleaned the ignition switch, Was there any rust/corrosion on the "B" post ?
