The switch cable loom

Friday, February 15th, 2013

To make things easier with the cabling, I separated the cable harness into its three individual looms: the lamp loom, the switch loom and the coil/flasher loom. I had intended to start with the lamp loom first, but then remembered (?) I had bought an “mod” for my AFM.
From www.pinballcenter.eu I had bought some LED backlighting for the green MARTIAN targets. I wanted to hook this backlighting up to the individual MARTIAN letters on the playfield, so that when the targets were in play and the corresponding MARTIAN letter lit, the actual target would also be lit. Hitting the target extinguishes the associated lamp, and would therefore turn the backlighting for that target off – a cool effect in theory.

In order to connect these target backlights up to the associated MARTIAN lamps, I needed to make some minor modifications to two of the lamp boards.

Having fixed the backlighting to each of the targets, getting them into position was unfortunately harder than it should have been, as the cabling from the backlight meant it was a tight squeeze for the target plus backlighting in the allotted slot. With some minor adjustments however, I managed to get them all in.

Whether it will all hold together in play, or even look good, is something we’ll have to see. Needless to say that this mod is reversible, meaning I can take everything off again, should it be necessary.

Playfield mechanics done!

Having got back from skiing it was back to the playfield and finishing off the mechanics on the back of the playfield (including the cable loom holders), excluding the playfield supports, as I’ll be putting these on last.
