[geppert]

I have a tester from my brother how do I check to see if there is any stray current in my tank?

What setting does it need to be on?

I checked voltage and got 0
Milli amps and ohms had a reading I think not sure how to use this tester it is digital with 6 settings 2v milliamps ohms and 2 amp

How To Test for Stray Voltage

1. Purchase or borrow a voltage meter. They can generally be found for less than $20 at most automotive parts or hardware store.

2. Turn the selector to "120 AC Voltage".

3. Insert the tip of the black probe into the third or "grounding" hole in an electrical outlet.

4. Insert the metal tip of the red probe into the tank water.

5. Watch the meter needle for any movement. Any needle movement indicates a voltage leak in your system.

Is this too much?
The article I read stated somthing had to be leaking this voltage and that item should be replaced.
I will see what it is in the morning.
