When I start my kubota l3200 the battery light stays on at idle, but goes off when I give it gas.
Comes back on when at idle again.

Could be voltage regulator going bad.

yup... loose belt is my 1st guess..
a 'bad' regulator shouldn't charge due to increased RPMs
battery could be going 'bad'.
Without knowing the internals of the regulator, it's not easy to diagnose IF the regulator IS going 'bad' however since the light does go out, that suggests it IS working.

If belt tension is ok,
1-battery terminals or wires corroded?
2-you might try swapping a battery - car battery for example and see what happens.

If your Kubota uses gas, then you have a bigger problem than the battery light

how old is the battery? Have you gotten it checked? Check power at battery powered off, at idle and at higher rpm. See if you are getting charging voltage to the battery.

That's what I was going to say, "Better step on the diesel". If all suggestions don't get you to the solution it might be easy to set up a mechanical gauge to see what the pressure actually is.

The common places to look for causes of the alternator light illuminating would be:

1) idle set too low
2) worn alternator belt causing slippage
3) belt is loose causing slippage
4) high resistance in the battery cables, clean and/or replace depending on condition.
5) poor ground refers to #4 for remedy.
6) alternator pulley is worn and the belt isn't riding on the sides of the pulley, but on the bottom of the pulley, but this is an extremely rare occasion.

If none of the above resolve your problem, remove the bulb, and the problem is solved. If the alternator fails, you will know about it when the battery goes dead.

Would black tape over the indicator work as well as pulling the bulb. I know it might be easier to do(-;

Amazing to me how many cars I’ve seen with black electrical tape over the check engine light. Out of sight, out of mind.

A slipping belt sounds like the most likely culprit and not a hard one to fix.

Yes, I thought battery terminals are cheap to check off the list. Just a film sometimes forms and is just enough to slow it down on charging.

I use this product on auto, motorcycle and my L35 and never have corrosion issues.
Check it out!
