52Carl, Would you enlightened us as to why 12 volts will fry a six volt rheostat for a light circuit? Some of us are still in the 'learning mode'. Thanks
My point was that 60 years of corrosion will doom a rheostat regardless of how many volts you put through it.
An original, non-corroded rheostat will do just fine on 12 volts.
(Sometimes I talk inside-out, due to my filthy German heritage.)
