First this is an AC motor with AC capacitors. Electrolytics will not
work on AC as a general rule. *Wrong.*

From Wiki:

Start capacitors above 20 µF are always non-polarized aluminium electrolytic capacitors with non solid electrolyte and therefore they are only applicable for the short motor starting time. ... If a motor does not start, the capacitor is far more likely the problem than the switch.

A non-electrolytic cap, AC or DC of that rating would be as big as a football, or larger.

The motor is 40+ years old. That is not 'newer'.

That covers both *wrong* things.

Winki lets anyone post anything.

My 50 uF capacitor is not electrolytic and rated for AC. It is no where
near footbal size. Not even beer can size. Even the 500 uF or so
capacitors for motor starters are no larger than a beer can if that
large.

People are quoting very old data. Maybe in 1950 the capacitors were
larger, but no today.
