The capacitors set the operating current of the lamp. If the lamp output
has changed rapidly, inspect the capacitors for swelling. The design of
the capacitors we use will burn open if it begins to short. A swollen
capacitor should be replaced and the unit should be tested to see that the
capacitor did not damage the P.C. Board.
To test the unit’s ability to switch power levels, make a manual exposure
at low power, note the voltage between the lamp lead common and the
low yellow (about 130V~, see diagram). Then switch to medium brown
(about 140V~, see diagram). Then switch to high power and note the
