Working on an old friend

Is there a maintenance manual I can find online to help me better understand the schematics of the circuitry of this machine.

There is a manual but it won't help you with the lights. http://www.pachitalk.com/forums/down...?do=file&id=64

Your machine has no electronics, your machine would typically have some switches, light bulbs and an in line fuse.
Another PT member (cardwwii) has some very nice sketches on the typical wiring for your machine.

My suggestion is to wire everything and test with the wires twisted before soldering.
The micro switch can be wired normally open or normally closed, it's always confusing to me, although I understand it! Better to test and verify.

a 1A, inline fuse is recommended if you use a wall power pack.
If you use batteries, the fuse can be omitted.
