Magneto voltage tester
I believe what I have in the photo is a tool for testing magneto voltage. But no matter which way I connect it the gauge goes down below zero. I was putting one end on the magneto output and grounding the other end. Car does run well on magneto. I was curious as to how much voltage it is putting out as we just got done rebuilding the whole engine and transmission.[image][/image]

Re: Magneto voltage tester
The T magneto puts out AC power
I believe that you have a tester for old “B” radio batteries that produced 45 volts DC.

Re: Magneto voltage tester
Thanks Les, I just put new batteries in my analog voltage meter will try it when I get home later.

when you get a reading from your voltmeter that you don't believe, don't worry, as a standard meter is not configured to give a meaningful reading. Do a search on "MTFCA magneto test" and use a lightbulb, or borrow an original or repro St. Louis Magneto Tester. This device is one of the very best items I have ever discovered during my "picking" days.

Re: Magneto voltage tester
You can also test it with the ECCT if you have the additional software.

Re: Magneto voltage tester
Actually, the standalone ECCT can test the magneto output is sufficient to properly operate coils without the software. The test scale is similar to the venerable St. Louis Magneto tester for those familiar with that instrument. The scale is somewhat meaningless; based on model year as opposed to voltage output but still serves the purpose.
The ECCT with PC Software provides a lot more information; Magneto RMS output voltage under load, no load, magneto internal resistance, Magneto magnetic field strength and engine RPM.

DC VoltMeter.
I have a meter just like it and it is a DC meter. It may well have been used to test old tube type portable radio batteries. voltage range is about right but many had a 90 volt "B" battery along with 45 volt and others. You can test the meter with a 9 volt battery or on Your car. Wire lead on top is negative. point on meter case is positive.If You hood it up to a magneto. The meter needle may jerk a bit depending on engine rpm but wont give a reading.
