Trying to solve an issue on a friend's LOTR.

The lamps in column 7 are ghosting when stepping through the individual lamp test. When testing any lamp, the corresponding lamp in column 7 will be slightly lit. Immediately suspected a diode.

Remove the Palantir Globe bulb (23 in matrix) and the issue disappears. I've replaced the diode, then the entire bayonet, no luck. Have also installed an alternate power board, issue remains so I'm dealing with a playfield issue. Removed all LEDS and installed regular bulbs in case an LED was shorted, no luck.

Wondering if the Palantir Globe bayonet is the incorrect part and therefore the diode is in the wrong configuration. Can anyone tell me, does your Palantir Globe bayonet have 2 or 3 leads?

Thanks!

Thanks for checking DCFan. Was not aware that the LEs had differences in the sockets and diodes as well.

Was hoping to get a solid confirmation on whether that bayonet has 2 or 3 leads. All other controlled sockets in the game have 3 leads, the Palantir Globe is the only oddball so I started to suspect it was incorrect. Diode could also have been reversed by someone in the past.

Thanks for finding that DCFan!

If that drawing/diagram is the correct bayonet for the Palantir Globe then it confirms my suspicion. Once upon a time someone installed the wrong part, 2 lead bayonet instead of 3. Makes sense, all other controlled #44 lamps in the pin have 3 leads.

Installed the correct part, issue solved.

To sum up, some dipshit installed a bayonet with 2 leads when the correct bayonet has 3 leads. Wish I would have noticed it sooner but there were other lamp matrix issues that threw me off.

Thanks for the help DCFan!
