I tried the relay fix on my RTV1140 Kubota without any luck. The relay I used says its a 12V 40A, is that not considered a small 12v relay, could that be my problem? The engine still cranks once or twice and then click, click, click same as before the fix was installed.
Well, simply use a HEAVY piece of wire to bypass the relay (like welding cable)
If the tractor starts, the answer is that you need a heavier relay.
If you still get click, click, click,, then the relay fix is not what you need.
There are literally a dozen or more things that can cause the problem,,
time to do a little searching.
I have replaced OEM cables with welding cables, and fixed the problem.
Where the battery cable hooks to the tractor frame can be dirty,, a little cleaning can cure the problem.
A ground cable bolt can be loose,, simply tightening the bolt can fix the problem,,
The clamp at the battery post can be corroded,, and on, and on,, and on,,,,
