Test a fuel gauge?

[40cpe]

Can I check a '38 fuel gauge with an ohm meter? If so, what should the reading be?

Thanks

You can use a 9volt battery to test if the gauge is good. It will slowly move, and that's all you want. I've tested several gauges that way. Make sure you on the right polarity, or it will just go in the wrong direction. It works for me.......
