Hi hsdancer,

You didn't give enough info about your pool to "diagnose" the electrical fault, but you did mention that disconnecting your "bond" wire (I assume that's another name for the ground wire/lug) stopped the voltage flow.

If I were you. I would get an 8' copper ground stake from the electrical dept. at Home Depot/Lowes (about $13) and pound it into the ground near your pool and equipment pad, then connect the chassis ground lugs on your equipment to the copper EARTH GROUNDED stake.

Many times, the "service ground" wire from the power company has a potential voltage above earth ground and a potential can develop on anything connected to the power company ground but grounded WELL to earth ground.

I can't THINK of a better way to ground YOURSELF than being immersed in SALT WATER and touching a source voltage! (lol.....sounds dangerous, doesn't it?

Also, I would worry about being able to physically "feel" 4.5VAC. Normally it takes a larger voltage than that to be able to feel a shock. (for example, the low 12vdc voltage but nearly unlimited instantaneous current flow available from an ordinary car battery.)

What I'm saying is....it may be a MUCH larger voltage that you're just unable to measure for some reason. (autoranging meter? wet spot not salty, etc.)

So I would also check that you have the electrical equipment connected correctly with matching "hot" and "return" lines connected the same way on all equipment.

You may have heard of rock stars who have been electrocuted by touching the microphone in wet weather (which is usually caused by plugging the sound reinforcement into ungrounded or reverse wired outlets) and you MAY be in a similar situation here, so I would check it out before you have a real accident.

Any indication of stray voltage like this is potentially EXTREMELY HAZARDOUS and is an accident just waiting to happen to someone who unwittingly makes a "better connection" and sits or somehow touches the wrong spot on the pool. Fortunately, it's a simple fix even if we don't completely understand why the problem exists.

Hope that helps
