It’s fortunate this isn’t a job, because my management style is to goof off first before not finishing a job.
In a rare and unheard of mistake I installed an electrolytic backwords with reversed polarity and ran it like that for about 5-minutes. Nothing flamed up and the circuit worked, but now I’m worried about that capacitor. It was receiving 4 VDC.
A further concern is the unknown age of the 50 uF, 16 V capacitor.
That’s why today’s endless search was first for my capacitor checking instrument and then for the manual that tells how to use it.
The capacitor reads a solid 68.5 uF.
