Nothing to do with Onewheel but...

[Lemur]

We had this 1980's pinball machine since the 90's and since my grandchild is growing up fast, it's about time to fire it up.
The machine came out with two fault codes for stuck switches, a real pain to open up the machine and see the miles of wiring and solenoids, but luckily, there was a manual online.
Turns out two small capacitors were shorted due to age and triggered the problem codes, replaced the .05m caps with .047uf caps and all is well again, I figured the "m" meant micro farads, so "uf" ?
