A couple of drops - not 32 drops, because they were small, at the very bottom of the "worm" gear (the vertical one that turns the hand wheel gear) that sits at the top of the motor - there's a bearing race under that gear that seizes up, or gets noisy, etc.
Check the brushes in the motor, I'll check tomorrow to see how accessible they are. Singer's usually pretty good, the brushes can be accessed without having to pull the motor on most machines. If they're less than about a 1/4" inch long, they need to be changed.
Other than that, if you do any electrical testing, unplug from the wall first. Don't do what I did on Monday, and unplug from the machine and "think" it's unplugged from the wall and grab the 2 terminals in the cable that mean business. Geez that hurt. Found my open circuit though. *shudders*
ETA: Yes, the 2 screws on the bottom of the motor, remove them, and the piece of plastic they're attached to, and look at the carbon "brush" inside the metal "tube". It should be 1/4" or longer.
The Bulb is a standard 15w bayonet style. Most Singer's used this bulb up until relatively recently.
