Mud and electrics dont mix .........
Take it to an auto leccy and get it checked properly, could need a simple clean, who knows
My mate paid over $500 for a newie fitted,so be warned the 24 V gear is exxy as

With a voltmeter measure the voltage at the back of the alternator (engine running at a fast idle).

It's possible your brushes in the alternator could be sticking due to mud.

You can remove the alternator strip it down and check. It might just need a clean out and new bearing/s and brushes.

It's also possible you may have got water inside the external regulator for the alternator.

Have you checked this?

If the regulator has a metal cover you can remove it and try and dry it out.
