Re: Card Reader HP65 - Need help Message #3 Posted by Tony Duell (UK) on 25 Mar 2003, 6:43 p.m., in response to message #2 by David Smith
Also check the leaf contact switch and the pads it makes contact with on the keyboard. In the HP65, one of the contacts is used to start the motor when a card is inserted. If that's not closing correctly, the motor won't start.
Carefully clean the ends of the leaf contact and the pads on the keyboard PCB with propan-2-ol (isopropyl alcohol).
I suppose it could be a problem with the sense amplifier chip on the card reader PCB (this chip also cotains the motor control circuitry) but that's a lot less likely.
