I know there's already a thread with the current draw in amps, or power usage in Watts for many games. However, I was curious how that total power usage broke down with the major components. So I had some time this evening to play with the clamp meter...
Here are results for a couple of my games, broken down by major sub-system. Typically, I'd make these measurements by using my clamp meter to get the "typical" steady-state current draw (in attract mode), then repeat the measurement with certain components unplugged and do the subtraction to determine the effect of that system on the total draw. In cases where sub-systems ran on 120VAC and the lines were easy to access, I'd measure them directly (i.e. monitor or marquee lighting).
Battle Zone (Atari)
------------------
total (typ): 1.6A
marquee & blacklight (together): 0.55A
monitor: 0.3A
game boards (both main and aux): 0.5A
Dig Dug (Atari)
--------------
total (typ): 1.3A
marquee: 0.25A
monitor (VisionPro): 0.3A
game board: 0.5A
Data East JAMMA cabinet with ArcadeSD board
-------------------------
total (typ) 0.5A
