My family owned an arcade back in the late 80’s early 90’s and I fixed alot of pinball machines but no early ones like the ones you guys do. Thanks for all the videos. Enjoy them much. Cheers.

Thanks glad you enjoyed our video presentations.

Thanks guys. Great info as always. You may think your repeat things but it helps us just seeing things dune even from different angles (or places) like the coil change in the machine. As always thanks for your time. Bob 👍

Hi Kim & Graham Royal guard might be the earliest machine to use the resistor in the series relay hold circuit in 1968. In 1978 strange world, Neptune, and Hit the Deck also used this resistor circuit on a 3A2B series relay. Great video as always.

Interesting Dave yeah we've not seen it before.

A late entry to the list might be Golden Arrow. It has a playfield layout that would easily allow the 3A2B series relay to be used.

Great information guys. Are those Zebra doves I hear in the background?

GOAT, Most EM pinball games run the lamp voltages , coil voltages, relay voltages through the steel metal and ONLY the WAFERS are providing isolation. If any of those WAFERS are not there correctly or have fractures it will SHORT out the lamp voltage to the coil voltage or relay voltages because the voltages are LIVE running through the steel metal material. What would you recommend using or doing to provide better isolation of the Lamp voltages, coil voltage, relay voltages that are running LIVE through the steel metal material to prevent short circuits?

That's the way some early EM games were designed. So other than ensuring that the earthing is adequate especially on the coin door I'd do nothing, except for repairing the initial problem.

@waynegram8907 I really have no idea I'm not an electrical engineer from what I've read it's purely for convenience. We always earth out the coin door for safety sake.
