Thank You Jason for your insight.
I will be getting a pwt meter the first of December.
I do believe I fixed my diode problem.
This time I connected it the right way round.
After 3 1/2 hours the mA meter is holding steady at a little over 1/10
mA., the water is crystal clear and just a little discoloration to the
electrodes.
Initally I installed a jumper around the diode with a single pole
switch. When I close the switch the mA meter reads .5 mA., which
indicates success.
When I close the switch and the meter reads 1.3 mA or so the ionic
silver will be done.
Polarity reversal is also working fine.
Thanks again Jason!!
