TECH: coin meters, theory

[erikthecat]

please someone confirm that in general....

coin meters are 12v operated,
the 12v is wired to one side of the coil and the meter is pulsed by a 0v being pulsed on the other side of the coil
polarity is not an issue.

the coin inputs are totally separate.
although a condition on these will cause a condition on the coin meters.

i realise that coin meters are not really used, but i'm just trying to be thorough.

i think that covers it all?

many thanks for your time in advance.

Regards,

GaRy

Re-polarity, make sure if there's a diode across the coil you get the
+ and - the right way round.
