Have a John Deer Sabre gx1542b120004. Will not crank. Solenoid w/n energize. Just get a relay type click from front of engine. Have no wiring manual. Battery reads fully charged 12.0v. Only checked the seat switch so far. Can my battery still be the issue? THANK YOU IN ADVANCE!

Hello Papadiesel:

From your Description it Sounds like a Safety Switch Problem. You can View a Breakdown/IPL of the Engine and Mower at this Site Addy, John Deere - Parts Catalog and Enter the Model Numbers (Sabre) and Click Find. Then Select your Model from the Search Results Area. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online. The Following is an Instruction File for the Safety Switch System. Any Input is Appreciated. The Color Code of the Wires May be Different than those I Use as a Reference in the Instruction File. **PLEASE REMEMBER THAT THE INSTRUCTIONS FOR CHECKING THE SAFETY SWITCHES IS JUST THAT!! FOR CHECKING ONLY. I NEVER Suggest a Mower be Operated with a Safety Device or Switch Disconnected or Bypassed. Now. On Some Model Mowers you can Simply Unplug the Safety Switch from the Harness. On Other Models you have to Place a Jumper Wire Between the Harness Terminals (on the 4 Post Switch (Clutch/Brake) Jumper from Same Color Wire white to White First and then Check for Fire, Now Include the Black to Black Wires if No Fire. Check the Clutch/Brake and the Blade/PTO Safety Switches First. Check the Seat Safety Last. Usually the Seat Safety is Not in the System for Starting the Engine. Just to Ensure Someone is in the Seat when Engaging the Transaxle and/or Blades. Use a Paper Clip or a Short Wire to Make a Jumper.** Usually if the Battery is Reading Above 12.0 VDC, then the Battery is Good. I Suggest you have the Battery Load Tested if there is ANy Doubt. Have Someone Watch the Volt Meter and Turn the Ign Switch to the Spring Loaded Start Position. If the Battery Shows Lower than 10.5VDC, then the Battery May have a Bad Cell and Require Replacing. If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. Thanks.

Good Luck
