I got this inexpensive mutli-meter at Harbor Freight that can tell you the value of your condensers. The reading is in nano farads though. As far as if they’re still good, you need a taster like a Merc O Tronic. How bad do you want to know? I have one and could test them for you if you wanted to send them to me.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
