Nikon F2: MD-2 battery polarity

[carsten_wolff]

<p>hi, the older battery holders for the motors on the F2 only have two live contacts going to the motor. I have got a dud (corroded) battery compartment but a nice, almost pristine looking motor, so I was going to connect 8-10 AA batteries just to see if the motor is working before I fork out money on a new battery holder. Naturally, i don't want to fry the motor, so, does anyone know which contact is + and which -? (inner/outer)?<br>

thanks!</p>

<p>There are markings on the MS-1 battery holder that identify the contacts - see this image here:<br>

<p>Thanks, Dieter, I actually only have a MB-2 holder and no battery inserts at all at they had been thrown out. This holder has 4 contacts/battery insert, but they're corroded away/unusable. I'm interested in the two live top contacts in the 6?-pin connector to the motor.</p>

The power supply was 12-15VDC capable of 1.5A, per specs. (~8 1.5V batteries, e.g.)<br>
