2014 Kubota l3200 hst starting problem

[Mike from MI]

Hi All
Need help with 2014 Kubota l3200 HST not starting. Sometimes when I go out to start tractor I'll turn key back to light glow plugs turn key to start and I get just one click sound, then nothing will not start, no lights will come ie flashers, head lights.
Will not jump start with a truck or jump box but when I hook up to my large charger fires right up with in seconds. Then it will stay fine for a couple of weeks and problem will return.
I have seen other post suggesting moving levers and petals around, has no effect on mine.
Anyone have an idea what's going on.
My first post
Thanks Mike

Next time it fails to start, I'd put a volt meter on the battery, then follow to the fuse box. And try to start at each. Is there a difference in the way the charger clamps to the battery then your cables?

Almost sounds like a loose connection, either on the battery terminals or ground strap.

I will give it a try the next time. Clamps are the the same on jumpers and charger as soon as I put the charger on it fires right up.

Thanks Mike

Have checked ground has good contact at both ends.

Just wanted to update. I took ground cable off battery and frame, took wire brush to frame and cleaned post put cable in vice put a little pinch on the crimps then put back on. Haven't had a problem since it's been about a mouth now.
Hope I don't jinks it with this update
Thanks everyone for your help.
