Dave, if you employ only the power supply, all of the tests are not available.

The capacitance test will not work. It requires an AC signal. R.T.

Mine uses a 7.5 volt 6 amp power supply to which produces DC voltage to the unit on demand, just like a battery would. It’s wired in to the mains coming into the unit so only one external AC plug is required. From the outside, the Merc O Tronic looks as original as the day it was made.

If I ever had to use it at a marina with no shore power to plug into, I do have a small inverter which could be hooked up to the boats battery to get the needed 110 AC power. The bases are covered!

Well, I got a battery and installed it. As soon as I turn the knob to “coil power test,” I hear the vibrator start to run. This is before I even press the test button. Is that normal? Also, without reading any directions, I hooked up a known good coil to the thing, in the same manner I would hook one up to my Stevens. Nothing happens with the meter, and I mean. NOTHING, as well as no spark, which I am assuming I should see in the little window? I tried turning the knob, which I think says something like, “increase, decrease,” but nothing. I guess I will read the “destructions,” but it is not looking good so far….

Long live American manufacturing!

Yes once you turn the switch on, it send power to the vibrator/ points. Read the manual and be danged sure you have everything connected properly or you will fry stuff.. I can make a short instruction sheet, unless someone already has…

Yeah, that’s how I hooked it up, both for the coil test and resistance. Just like the Stevens. Hmmm. Well, the only cost I have is the new battery. The machine was a hand-me-down from work.

Long live American manufacturing!
