Ko Vantage problem

[qatmix]

Hi All

I recently got an old esprit hand unit. The one without the digital screen. It was dead when I got it, but I have managed to get it up and running now to a fashion.

The issue I have is that the light comes on, but the voltage dial doesnt increase. It was working initially, however after I left the unit on charge overnight (it has rechargeable batteries in it) the dial just stays at zero.

I think it might be one of the plugs inside (One of the ones with 4 wires coming out) but needless to say, I havent a clue where to get a spare plug.

Any ideas? or anyone with a very old dead vantage they want to get rid off?
