I just received a well loved ic-w32 from ebay. I need to get a new battery and a charger for it though. Both are expected.

Before I do, though I'd like to make sure it _actually_ works. I have a variable DC power supply I was thinking of either bypassing the battery with or powering via the external dc jack. I don't know what the contact middle contact does though, so I'm hesitant to try that idea. Need to keep the magic smoke in ...

Does anyone have experience doing this? Maybe information on the DC jack polarity? The service manual I found online doesn't mention much about powering it up.

Any others tips or pointers on the w32a I should know?

Thanks for your time.
