I am working on a Crest Ultrasonic cleaner , through the inside it leaked liquid on the corner PCB on just one almost C battery sized inductor with steel core. I've replaced diodes and transistors and the board powers the machine correctly but the bad inductor will burn if I run it more than 30 seconds. There are four inductors which feed each to one of the 4 transducers wired in series.
It seems that the inductor is prob a 20awg with what I would say at least 250+ turns with a metal core. (Looks like a speaker crossover inductor).
Could I test this to get a close enough value with something like this ?

or would I need something else , this meter starts at 2mH I think this would be ok given I unwound the bad inductor and got at least 250turns but the wire broke up and I could'nt properly measure more.
There is no schematic per pcb part number on the internet there is no
markings on the inductors . The company that manufactured this has no schematic due to being older model .
