Some weeks ago I went out to start the Z710A. I have a Battery Tender connected to it to keep the factory installed battery up to 12 volts. It wouldn't turn over to start. First thought comes to mind...dead battery!! So, I removed the battery and put it on the work bench and connected a charger to get it back up to 12 volts. Every day I would check to see if the battery would lose the volts...it checks 12.5 volts each day for 10 days. So, I removed the positive/starter cable and cleaned all the connections, including the wires to the coils and other wires and installed the battery. Still no turn over or anything on trying to start. Next thought came to mind... a bad ignition switch. Order one and received it today. Installed the new one and turned the key and same old thing... no clicks, no starter bendix turn over. I had installed a new PTO switch last month, as I was having some mower deck shutting down last fall. Removed the new PTO switch and cleaned all the connections and reinstalled it. Still no start.
Now here is the 'strange' part of this whole no start problem. If I pull the choke lever knob up it will start as if nothing is wrong. If I try to start the tractor without any coke, it won't make a sound...no starter Bendix turning. This choke lever is mechanical...no electrical ...just a cable going to the carburetor... What "moon phase" or we in this month? May be connected to the 'government shutdown!!!!
