Default Re: Understanding Dual Can Electrolytics

Thanks Mark - connected up my DMM as suggested across both +ve terminals but no idea what is going on!

Resistance reading rose rapidly to 14.6MΩ and then dropped slowly to around 10.8MΩ ?

It's slowly increasing again after about 10 minutes and is currently at 12.36MΩ ...

I'm no stranger to re-stuffing but just thought I'd try and get a better understanding of dual cans:-

When I have time I may attempt the Electrolytic Capacitor Reformer suggested by Adam (PsychMan) but would need advice on where to source those small meters!
