[Mgs] using a volt meter/72 Midge

Hey Steph, don't be afraid.  It is easy to use a volt meter.  The  setting on 
the knob will indicate the scale of the reading.  At this   point, you are 
able to ignore all of the amp settings.  A volt is the  amount of electrical 
"pressure".  Think of a hydraulic circuit, PSI is a  measure of hydraulic 
pressure, PSI = pounds per square inch, volts = electrical  pressure.  Our cars have 
12 Volts of electrical pressure from the  battery.  IN order to complete a 
circuit and have something happen, (i.e. a  lamp light), the electric circuit 
must go from the battery to the earthing  point, positive (+) to negative (-).  
If a circuit is "grounded" before the  circuit is completed, the action will 
not happen.  
 
The ohm scale on your meter tells the amount of resistance to circuit flow,  
measured in ohms.  The closer you get to ground/earth/negative the lower  the 
ohm reading.  Does this help?  Let me know and perhaps we can talk  on the 
phone.  Electronics is my game.  Regards,  Tom
