It is important to measure voltage when light is connected to the pack.
Power must remain On.
1• The first step is to try replacing
the spa's light bulb.
4• If "Light" indicator appears, but
light still isn't working, make sure
light is at highest intensity setting
(indicator solid light, not flashing),
remove plastic cover and measure
voltage between opposite prongs
of connector P14 on the board.
If you get ≈12 VAC, replace light
socket.
5• If you aren't getting a voltage read-
ing, replace light fuse on the board.
6• If the problem persists, replace
board. (Refer to "How to Replace
the Board" section.)
