I have acquired a Fluke 8810. It has the AC and the Ohms options. At first the display was erratic, there was a faint hum, and there was a clicking noise on some of the functions. This turned out to be a bad capacitor in the -35 volts section. Having fixed that The AC and the DC functions seem normal. However the Ohms function seems to settle on flashing what the manual describes as an overload display -18.8888 or something like that. I suspect that the Ohms board itself has an issue. There is what appears a little LED on the board that does not light up. I think the board is not getting power.
However there is precious little information on the board itself. Which lead is the power lead and what should be the expected voltage? Does anyone know anything about this "ohms conversion assembly"? Does anyone have one laying around? I might buy another meter for parts, but before I do, as any tech would, I want to find and fix what is wrong.
