My fuel gauge and idiot lights on the B7200 HST won't work now. Actually they are intermittent as to whether or not they will work. Because they may occasionally work I'm guessing it's not a fuse issue. Is this common and where do I fix it?

I'd look for a ground wire. No idea where it might be.

Do you have an operators' manual?

If you do not, start a Conversation with me by clicking on my name on the left of this post and send me your email address.

There are two fuses in individual in line fuse holders as shown in the following:

With issues as you describe them, I would be looking for wires damaged by rodents.

Loose terminal… either at the panel-ground or the power-lead.

RODENTS! Those little buggers carry trash in from long distances to nest in my mower engines. I stored insulation in the barn, come spring I start the tractor and pink snow is everywhere.

Went chasing bad wires or bad grounds. At some point the dash started working. I just don't know when it happened so I'll probably deal with this again. Thanks to Dave_eng for the manual connection.
