[GreenKeys] Margin Indicator

[Don Robert House]

Larry,
ersonally
As far as I know all the later machines have 6 volt indicators.  I  
believe it was a safety upgrade.

Howdy Gurus,

Why do some machines have 60 volts to the margin indicator and other  
have 6 volts??  Is one an improvement over the other?  Were machine  
cabinets converted or were there two types in the field?

Curious minds need to know!
