Fried Volt Meter

[MikeCas]

We have an MEP 804B that runs unattended to power a submersible well pump. It has been dependable and generally trouble free for several years and about 16,000 hours of use. A few days ago it shut down after about 5 hours and we found the voltage output meter burned up. It looks like something shorted out in the meter. What could cause the meter to burn up like this? Do we have a bigger problem somewhere or is there anything else we need to check before replacing the meter and starting it up again?

electrons had a party. It looks like one connection was loose and that makes heat. You're probably fine with just a replacement meter.

That part often goes bad, but not like that. I have seen a few burn out like yours, but its very seldom. Like Scooby, I think you just need to replace the meter.

Thanks for the replies. That's what I suspected too but I wasn't sure. I have one ordered that should be here next week. Some of the other wiring close to the volt meter got pretty warm but I didn't see anything that looked liked the insulation was compromised. I will check it out and put the new meter in when it gets here and we will see what happens. Thanks again for the help. You guys and these forums are great!
