I need help with a very strang problem. I have a 60" Exmark Lazer Z with a CH22 Kohler Commantd motor. This mower is strickly used for my house. My friend gave me this mower 5 years ago without any issues until now. Spring time it was working fine. Sometime around June I went to mow and nothing happened. No sound, no motor turn over nothing. I thought it was the key ignition beause after 5-10 minutes of off/on with the key, the mower started like nothing happened. Month later (hot summer and no need to mow) and went out and same thing. No turn over, no start, no sound. I replaced the key ignition switch and same, nothing. I replaced the 12V solinoid switch and same, nothing. I tested the starter by using batt cables from car to starter and nothing from the starter. So I replaced the starter w/ solinoid. Wednesday after installing starter, I tired again and nothing. Maybe the batt is dead so I jumped batt from car and and nothing. Tested the new starter(direct pos batt cable from car) just to make sure motor was not seized and motor almost turned over. So I charged batt some more and then turned key and mower started. WOW, I thought everything was fixed. Went out last night and again nothing. I was thinking probably batt is dead so I tried jumping batt again (just to finish the lawn and then I can replace the batt) and again, nothing. No sound no turn over????? Tested batt with voltage meter and I have juice. Tested batt pos cable (neg to pos solinoid switch) and same voltage. Now I tested opposite side of solinoid switch (small pos cable runs to solinoid/starter) and I get no voltage. Now I'm not sure if I should get voltage since I'm running vol meter from neg batt to other side of solinoid switch??? Like I said above, I get juice from neg batt to sol switch (bypassing pos batt cable). What the heck is wrong? Any input would be greatly appriciated. I hope my story is not too confusing. Thanks.
