First lets check the main buse fuse little tip you cannot check the buse fuse in the circuit board you have to pull it out so you can check the continuity.
Hi, I pulled main fuse and there is continuity. I pulled all the others on the control panel as well and checked. Thanks, Dan
Ok fuses are good now you need to check the transformer un plug it from the circuit board and test it make sure you have power going to the board itself.
Problem solved. I was confused why I was not getting 220 Volts across the posts on the control board. I measured 120V across the post and ground so thought things were working. However, I should be getting 220V across the posts. To make a long story short, the shut off breaker switch went south. In the on position only one of the power lines connected through to the hot tub the other was broken. If I bypass my shutoff switch everything is working. Off
to the hardware store to find a another shutoff switch. Thanks for your help, Dan
