b. If you are installing a different type of lamp from the original,
ensure the correct position of the anode yoke. (Figure 5-55)
c. Insert the threaded cathode (-) end of the lamp into the negative
lamp connector nut located in the rear of the lamp compartment.
(Figure 5-56) Using both hands, hand-tighten this end into the
threaded nut. CAUTIONS! 1) Handle the lamp by the cath-
ode/anode end shafts only, never the glass. DO NOT
over-tighten. DO NOT stress the glass in any way. 2)
Check leads. Make sure the anode (+) lead between the
lamp and igniter is well away from any projector metal
such as the reflector or firewall.
d.
EXPLOSION HAZARD! DO NOT apply torque to the
anode end of the lamp. Rest the anode (+) end of the lamp on
the anode yoke and slip the positive lamp connector over the bulb
end. (Figure 5-56) Using the 5mm Allen key, squeeze together with
the anode clamp making sure not to place any torque on the lamp
quartz tube.
e. Tighten screws in both negative and positive lamp connectors. IMPORTANT! Proper electrical
contact prevents resistance in the lamp connectors. CAUTIONS! 1) Handle the lamp by
the cathode/anode end shafts only, never the glass. DO NOT over-tighten. DO NOT
stress the glass in any way. 2) Check leads. Make sure the anode (+) lead between the
lamp and igniter is well away from any projector metal, such as the reflector or fire-
wall.
f. Re-install the front lamp duct.
