Hi marmichalsku,

thanks for sharing the information, I was desperately searching for this kind of information!

I'm trying to reverse engineer the Multivolt system of a massive Hikoki impact driver: I have 7 contact blades on the tool.

The shape of the connector is such that C+ and T are not used, however, a contact on V is present indeed.

So, I'm wondering: do I have to apply a voltage on this pin, if I want to trick the impact driver to think he is connected to his Multivolt battery?

I don't have access to batteries or chargers at the moment unfortunately.

Maybe you guys can give me an hint here, it would be so appreciated.

Thanks in advance and best regards,
