Use a continuity tester or a multimeter set to ohms (should end up close to zero) to check the connection between the terminal on the left end (behind the plate you removed) and the pin it goes to on the vibrato board. Next, check the connection from the terminal on the right end to the ground screw.
Spray the two pins with DeOxit or a similar electrical cleaner. Use a cloth or your fingers to clean any gummed grease (gunk) from the gears. Spray the gears with Lithium grease ("White" grease) and spray the bearings also. Turn them to let it coat the gears. Try not to get grease on the capacitor strips or the electrical connections.
-Next we move on to the brushes. In each end, there is a terminal, two springs, and two circular magnets on each spring with a brush going through it
. Test the connection between the brushes
and the terminal. DO NOT spray anything on the brushes except electrical cleaner if you so desire.

+You will need to put the drum back on the left plastic end first, because of the clips. Carefully fit the pin through the hole into the chamber with the springs/magnets. Then, with a pair of needlenose pliers and small fingers, put the two magnets back on the pin. There is one spring that is mounted lower than the other; put this one on first. The pin should go through the hole in the middle of each magnet.

+The springs and their solder joints can become stiff or out of position, causing squeaking or bad connections. Once the magnets are on, heat each spring for 15-20 seconds with a soldering iron, being careful not to melt any plastic. Next, melt the solder at the end of each spring fully and let it re-set.

+Do the exact same things to the other end of the scanner, and put it back in. DON'T DAMAGE THE PINS. Bolt everything back in, MAKING SURE to put the rubber o-rings back so that they cushion the joint between the metal axles and the chassis. Remember, it'll be a tight squeeze to put it back in as well.

+I tried to make this as clear as possible; feel free to drop a note here if you want clarification on anything or have questions.
