Stern POTC, picture is of capacitor and light in circuit to ship motor. Ship motor not working in test/game mode. I presume to be a light and what is its function? To let one know power is getting to motor?
From Wayout440 :
It's a cheap way to protect against inductive kickback from the motor:
"Controlling arc damage from coils and motors is done by suppressing inductive kickback. For lower power applications, such as small solenoids and fractional horsepower motors, shorting is the simplest method. Shorting can be accomplished by using a metal oxide varistor (MOV), a neon lamp or a spark gap. An MOV is the most common component used to suppress lesser energies. These devices represent an open circuit below their specified rating and become conductive above that rating. An MOV is connected directly to the terminals of the coil. When the coil is disconnected, its voltage starts to rise, and when it reaches the MOV rating, its output becomes shorted. All arcing is suppressed because the kickback voltage is never large enough to initiate the arc in the first place.
A neon lamp serves the same basic function as an MOV, with slightly less precision and at lower voltages. In this case, when the voltage climbs high enough to light the lamp, the inductive energy dissipates through the element. When neon lamps are used for transient suppression, they are placed in the same location as the MOV"

Lloyd, you are an absolute champion in helping us all out. Greatly appreciated.

Quoted from J85M:Thank the pinball gods we have you Lloyd to answer stuff like this.

Not me. It was Wayou440 and Ken Layton. Their previous help is still helping.

He says who the info came from, Read a little next time hey But thanks Lloyd for the copy and paste

He does indeed say that, think you maybe read a little too much into it, I was praising Lloyd because he either knows the answer himself or knows where to find the answer, both are equally as important (no point having the answers out there if no one knows where to find them) and whether the answer is provided directly, or just linked, a simple thank you for taking the time and effort to reply is just polite.
