Zt hd 48 will not start.

Mowed my lawn this morning. After mowing I used the blower to blow the mower off. I went to put the mower in the garage and it will not start. I hear a loud click when I turned the key. Check the 25 amp fuse it was good. Checked battery voltage it was good. I jumped the solenoid with a scew driver with the key in the run position and it started. I guess the solenoid is bad? Brand new mower with 13 hrs and already problems, not happy about that!

Solenoid is probably good, do not change, hands on check all electrical connections, plugs, switches, relays, you probably just knocked a wire loose using blower.

I checked for bad connections but all seems good. I'll take a look at it again.

to check the solenoild run a + wire to the trigger which is generally a small terminal near the base.
If it has 2 small terminals then one is + and the other is -,'
Blowing you have most likely blown one of the rigger wires off, happens all the time.
