Kurt, Thanks. That makes Sense. I will do that in the morning. After "setting it" do I turn the pointer to the proper voltage for my car?

GRutter. Yes, I opened it up. I replaced the three "C" cell batteries. I cleaned the minimal corrosion.

As it has a set pot that Kurt mentions, there may be a battery inside the unit. Turn unit over and see if it mentions an internal battery. Enjoy the dwell tach meter.

Herb, excellent. I wiped off the lens earlier and I think I caused the static electricity! I did try to adjust the meter. I'll try with a damp cloth as you suggest.

Thank you all for your responses. It seems like it is in pretty good shape. The wires have a few cracks in them, I may replace them.
