A simple tool for that task is a vintage Bell System "brownie" or "kick meter".
Originally used for detecting grounds on phone lines, it is an analog d'Arsonval Ohmmeter with a 45-Volt battery supply.
It reads high ohms at that potential, and has a polarity reversing switch that is really handy. Once you get used to what it displays, the results are spot on for me and those pesky old caps.
