ok to make a long story short,
question 1
i have a pump that was with the old spa pack, got a new spa pack
plugged in the pump into the spa pack and it kept blowing the breaker
so the guy who sold me the spa pack told me i could wire the pump directly into the box
this is because the spa pack is 220 and the pump is 110
now the pump is a 2 speed pump so how/what do i need to do to get both speeds
it has four wires. i think i need some sort of toggle switch.
i do realize i have to go through a gfi so that i don't kill myself.

question 2,
even when i hook the pump up at full speed,
i'm not getting any heat from the spa pack,
the power light is on.
i measure 120 on both the black and red,
it is an old seahorse one.
if there is heat going through it and the light is just burnt out, how can i tell?
or is there a relay or something that has to be hooked up with the power of the pump?

thanks in advance

I can't help you too much on the first one other than I don't see how wiring directly in will help. I'm not the complete expert, so he may well know something that I don't.

On #2, my first guess is that the heater element has gone "bad". If you can disconnect the heater wires (and with the spa completely powered down at the breaker), measure the resistance between the two terminals of the heater. It should be in the ballpark of 15 ohms I believe. If it is zero, that means a short while infinite resistance indicates the element has burnt out. My shot in the dark guess is that the heater element has burnt out. Since you're directly measuring at the terminals of the heater, I would likely rule out any kind of pressure switch problem.

What voltage do you get measuring from red to black?? If you don't measure 220/240, you're not getting proper power to the heater.

Good point - it would be 120V neutral to hot (240V hot to hot) going into the box, but by the time the electricity goes to the heater, you should have the full 240V (assuming a 240V heater of course).

Thanks, Dr. - I read that too quickly and assumed
