Onan Generator digital hour meter issue?
I have an Onan 2500 Generator in my Arctic Fox camper, and the Genset runs fine, switch works perfect, but I'm getting no reading from the digital hour meter. I called Cummins/Onan and they make a big deal out of getting a serial # off of the generator etc., thus more trouble than it's worth, as since it's just the 12V meter, it should be a simple meter, which should work on them all if I'm not mistaken? I see there are at least a couple of different models that sell on Amazon and other places, but I thought I'd ask here if replacing the hour meter seems like a normal issue with these generators? Some try selling the whole panel, with the switch in the panel as well, but my switch works fine.
Is there any particular things I should know in replacing the hour meter (I see on Amazon they are in the $16. range, and on other sites up to $30.+ and there is even a Youtube video on a fellow changing his out on his motorhome, but I thought I'd ask here to see if others have done this in the past, and if there is any difficulties in purchasing one of these units and having it fit?
I did pull the panel off, and there is 12v power to the digital hour meter, but I'm just not getting a reading!
Thanks for any suggestions/advice!
