    Thanks indeed! What a great learning experience! Once it is all working again I'm going to go back through all the connection points with the meter so I know what normal is supposed to look like.

    I checked with the neighbor just to make sure he didn't switch the wires in the junction box or the heater (I didn't think he did since he thought he solved the problem at the breaker box - but I wanted to be sure)

    So I switched the red wire and the fuse back to the other breaker, flipped the breakers back on and immediately heard the heater kick on. YIPEE!

    I put the meter on the upper element screws and got right around 240v. Then I tried the bottom and got 0, but I remembered what Mark said:

    That is good info - and makes sense now that I understand a bit more.

    Many thanks guys.

    TEMPIC... you just said the words I have been waiting to hear all day... 240 volts (or so) across the element... LOL. Take care pal!

    Tempic,

    I'd like to thank you for this bug, but I won't. :)

    Enjoy the hot water, now that winter is almost over! :)
