Kubota B-21 instruments quiting

[Boomologist]

Hi,
New to this site. Appears there's a lot of very knowledgeable people here and I hope to get some help.
I have a B-21 and the problem started with the charging gauge failing followed by the oil gauge then the temp gauge. These all quit over a period of a week. Now I noticed the work lights have quit. The 4 way flashers still work as do the turn signals.
Has anyone had this issue?
Thanks,
Ron

Have you inspected behind the panel for possible rodent damage?...another thing to look for is disturbed ground wires links...

Check to make sure your battery and alternator is working correctly.

How old is your battery?

Hi,
Just discovered the problem. There are two connector blocks on back of instrument cluster. These connect to very flimsy copper strips on circuit board (actually not a board at all, just a sheet of thin plastic with copper strips embedded in it). Some of these strips got corroded and one actually burned away from electrical arc.
Tried to move wires to other locations in connector but couldn't get them pulled out. Tried every trick I've used but nothing worked. Finally ran a thin strip of solder over the copper strips and even managed to replace the missing strip by flowing a solder trail where it had been.
It works!
BTW: the circuit board doesn't even show in the dealers parts book.

My tach/hr meter went out and I noticed the instrument panel to be a little on the cheesy side. But everything else works. Previous owner kept it outside so that is part of the problem. It is a Garage Queen now in its old age so I think it is stabilized. Good little tractor.

My B21 has been inside most of its life. I don't know how/why those contacts would corrode like that. A couple looked like a bad battery post with the acid buildup.
