I have an older Morgan Spa (1992-93). The light switch stopped working so through processof elimination I found and corrected the problem. During that process I accidentally touched the heater rocker switch to the control frame. I thought I had turned teh power off.....wrong. It made a large spark. Now the only thing that work is the darn light (ironic). Any ideas on what would be affected by shorting the heater switch? I can check teh micro switched easily with a multimeter. How do I go about check a relay or the GFCI? The fuse is still good. Could the problem be a bad GFCI because when I push either the test or resetn button it doesn't do anything (doesn't "pop" like a GFCI would normally do).
