1. Check input voltage to the light transformer at the primary side across terminal 1
and 5. Should read 240 volts. (see picture) If you do not have 240 volts across 1 and
5, check wiring back to the terminal block. If there is 240 volts present at 1 and 5 go to
step 2. (see picture)
Step 1
2. Check voltage at the light transformer on the secondary side across terminal 6 and 8. Should
read 12 volts. If you do not have 12 volts present at terminal 6 and 8 replace light transformer.
If you do have voltage present go to step 3.
Step 2
Step 3
4. Check voltage at OL1 on main relay board. Should have 12 volts present after OL1 relay
closes. If you do not have voltage present recheck steps 1-3 or replace relay board. If
you do have voltage present Check wiring to light socket and light bulb.

1= 0V
5=240V
6 to 8 = 12 VAC
8 to 10 = 12 VAC
6 to 10 = 24 VAC
8
3. Check voltage from the main relay board at terminal N which is to the left of OL1 relay.
Should have 12 volts present at N all the time. If you do not have 12volts present re-check steps
1 and 2 or replace light transformer. If you do not have 12 volts present go to step 4.
