Plugged in the electric fencer and the meter reads ?short? but it
still shocks the **** out of you. Don?t ask me how I know this.
Not having a volt indication will be a real problem, no way to know if
grass etc. is knocking down the effectiveness. A fencer puts out a
high volt burst a small percent of the time. On the order of 7K volts
for 50 miliseconds once per second. Is there an easy way to add a volt
meter? Just a relative indication is all that?s needed. or time to buy
another unit? ($250)
Karl,
Most fence chargers are prtetty simple, I have schematics of a few
designs. What brand is yours?
Units with a meter typically connect the meter to a 1 or 2 turn
secondary on the output transformer. Depending on the design of your
charger, the meter curcuit can be as simple as a diode and a meter
movement or somewhat more complex.
It would be well worth your while to open the charger up and take a look
at what you have. It could be a bad meter movement, a bad diode or even
a dead insect in the meter movement blocking motion. Supposedly, the
movement is sealed os a bug can't get in, but as you probably know they
can get into surprising places.
