My free inverter came with a rilly cool remote control/readout that absolutely does not work. Even though the whole thing is nearly 20 years old, new remotes are available but extremely expensive: Like in the ballpark of $500. And mostly what it does is control inverter modes I would PAY mine not to do. All I really want it to do is tell me what the $%^& battery voltage is. It won’t do that, either.
I have looked and looked for a digital gauge that would tell me this. Even ordered one, but it turned out it couldn’t handle the amperage. My multimeter has been permanently parked on top of the inverter for years, that being my only means of reading the voltage, and it’s just ridiculous.
A few days ago I was in the auto parts store buying spark plugs for the Jeep.
And I thought, “Well? Why not?”
I’ve said it before: I will go full redneck when I have to.
