First, unplug the jack pressure switch for the proper jack. If the red
warning light goes out, replace the jack pressure switch. If the light
does not go out, unplug the warning switch wire. If the light goes out,
replace the warning switch. If the light does not go out, check the wire
for a short to ground. If the wire is ok, replace the control box.

go out.
Unplug the 2 pin MTA connector and check the ground wire going to
the master warning light. If it is not shorted to ground, replace the con-
trol box. This light should be on whenever a warning light on the touch
panel is on.

The green travel light will not come on if any red warning lights are on.
If no red warning lights are lit, replace the control box.
