I have a 6420 work caboose with a searchlight. I can't get the light to work. It either doesn't work or it shorts out. It seems very sensitive. Can someone Describe how to get these to work. I have checked the bulb and it is good. Better yet, if someone has the repair manual page, I will be forever in your debt. My repair manual, (published by K-Line)doesn't have the 6420, only the 6419.
Thank You,
Bill von Tagen

Check the wiring from the roller pickup to the bulb socket. Chances are the insulation is bad and may be shorting out to the truck or the frame.
Rewire the caboose and your short should be gone.

See Lionel Supplement 18:7-3 available on the Lionel website. SEE HERE. It is a unique mechanism:
The searchlight post (2420-11) is hollow, insulated via a thin paper tube (2420-13) from an internal central "plunger" (2420-17) that touches the "L" shaped spring contact underneath (2420-18). This is insulated via the appropriate fibre insulators (CH-46) from both the frame and the screw. The "plunger" runs up into the bottom of the housing (2420-4), touching the normal contact on the back of the bulb (1402), with the circuit completed in the usual manner via the housing itself.
Check that the paper tube is present in the searchlight pole and the thin insulation strip underneath the searchlight contact the brass rod rides against.
Thank You all.
