Zero Turn Start Issue

[Johnwat]

My ZG124E has had start issues almost from the 1st day. With a fairly new battery, I will just get a engine click when turning the key. After several attempts and clicks, the engine will sometimes turn over, sometimes not. I have replaced the switch with no change and am about to change the solenoid. If that doesn't work, should I change the starter itself?
Thanks so much.

Battery cables / check high current connections

Since it 'clicks', the signal TO the starter solenoid seems good, but not enough current to spin the starter.
Or it could be a 'bad' starter solenoid, or 'bad' starter.

'since 1st day'....
is this a brand new machine ?
if not how old ?

It is not a new machine but it does not have 100 hours on it since it is at my weekend place.

not new, so could easily have corroded primary battery cables.

When I had similar issue was pto switch. Volt meter going to be your best friend here. See where you have voltage and where not.

I have 2 Ford tractors that do the same thing. On my tractors, it's the solenoid that is not making a solid connection when it is energized. These solenoids are not rebuildable, meaning I cannot open the solenoid and polish the contacts to allow them to make a better connection. I used to do that with the older solenoids.

aww, you just drill out the 4 rivets in the corners and then everything flies out , all over the place !!
When you find the 'bar', install upside down, then use a fine dbl side flat file to 'mate' the contacts to minimize pitting. I use 6-32 nuts and bolts to secure the case halves.
I was always going to add a capacitor across the studs, just like the 'condensor' with 'points'.

I have in my files this recall or service bulletin for ZG mowers regarding brake switch.
I do not know about this issue just filed the document.

brake switch almost always is the culprit on a click but no start condition. Occasionally bad connections or bad ground. Check the engine mounting bolts (especially you Kohler guys...)
