Mep-802a - amp meter not working.

[Guyfang]

1st thanks for all the reply's. I would have responded with the my findings sooner had it not been for an episode of the old Covid-19. I am better now and put a multimeter on it and checked the voltages at MT4. There is voltage so I am confidant that the meter is bad. It looks to me like there is brown corrosion inside. I would guess there is no way to rebuild because they are sealed. (Wrong. I have opened them up, and fixed a few. Not many. But it cost nothing to at least look) Any suggestions on where I can get a new one? I didn't see any on ebay. (use 26-5773 part number. Cost 20.00)

So 2nd question. I will open a new thread if people think it applies. When I started feeling up to looking into the issue with the Meter M4, my Temp meter M6 starting acting up. Start the gen and it would sit at lowest setting then maybe the dial would come alive and settle on a temp (around 180). The temp meter stopped reading all together. I purchased a new one off ebay and installed it. At 1st the temp would settle out at 200 degrees. Just today I noticed that the temp now settles at 218ish. I checked the meter and it has a burnt electronic smell definitely coming it. I am thinking it is going to need to be replaced again. I should also mention the gen does not act or feel like it is overheating. So is there a way to measure if the meter is actually accurate? Aside from ebay any recommendations for a place to buy one of these? (Use a thermal heat measuring gun to check the real temp. Then think about looking someplace else for the problem.)

I just used up my last ammeter in my parts stock, so I might reach out to that Korean firm to see if there is anything better that can be done on the price (freight is almost twice what the purchase price is). Thanks Guy.

Are the posts marked?

I don't know what I am thinking. I was looking at the wrong Gauge. M4 only has 2 post. The meter from Oshkosh will work.

I was wondering about that.
