Relay solenoid armature lubrication
Is it advisable to lubricate the armature of a solenoid.
as the starter on my car failed to engage, and after a tap it worked.
On the L1011 the pax door locks were solenoid operated and we were told never to lubricate the sliding plunger.
I took the starter solenoid apart and cleaned and polished it, and assembled it dry.
any info or regulations would be appreciated.
