ZT48 XL Single click when starting

Read the instructions in the pdf file first. I listed one from Amazon. It is purpose built for John Deere. You can buy a 30 amp Bosch relay at the parts store and make up your own wiring for less.

Yes, this fixed my Grav.....start assist relay. Common problem, easy fix

FYI
I just replaced the starter on my Cub Cadet with a 60.00 Amazon starter, worked once, the day I installed it,
31 days later solenoid wouldn't engage, 1 day out of warranty
Not saying you cheaped out like me, but don't assume the new starter is good.

Just for fun. Take spark plug out and see if gas shoots out of spark plug hole when you turn it over.

Why would you care if gas shot out of the plug hole? He said it just gives one click. It doesn't turn over. I think it may be a broken wire.

Not really a bad suggestion.
I had a 'click' with no turnover a few years back.
Problem was that my needle valve stuck open and flooded the engine.
The cylinder was hydrolocked.
Pulled the plug, hit the key and gas shot out of the cylinder.
Changed the oil and put a manual shut-off in the fuel line and 'all is well'.
.....another lesson learned.

Replace the battery

Gravely ZT48 XL - only single click when starting. Replaced ignition switch, starter solenoid, starter, seat switch, cleaned battery terminals, tested starter relays (they were good), battery tested showing 12+ charge. Any ideas? The only thing I can think to do now is replace wiring.

If you have not done so, you may want to clean the battery negative connection to the frame. I have seen those rusty or mostly painted so the only electrical contact is a few threads from the cable bolt.

You have never said if u tried jumping it with cables to full out bad battery. Could be electrical or could be mechanical. U need to first rule out which one it is.

I might get some naysayers but the first thing I might have done is jump it from my car battery.

You need to test every component. Put a hot battery cable directly to the starter hot terminal momentarily and see if the starter is engaging and spinning. If you have tested the relay that would have eliminated that point of failure. Try a different battery. Batteries can show 12 volts and still not be strong enough to engage the starter. I have several old car batteries like that. I use them on my electric fence. Another possible point of failure is the terminals. They can have a good connection to the stud but be corroded on the inside where pressed onto the wire.

I don't know much about the Gravely motor, but B&S is really bad about the compression release going bad, so when you try to turn it over it can't get by the compression stroke. It just clicks and sits there. Might be something to look at.
