Before removing the top, did you check the bottom? If it is like the SP, there will be a contact for the battery compartment mounted on the casting. Check this first.
If the meter does not respond at any shutter/film speed setting, then the coil in the meter is open. I believe circuit is a bridge and, unless the meter is open, the needle will respond when the switch is operated. The next area, most common, is the asa speed resistor has failed and it is operated by the shutter/film speed selector. Hope this helps, Bob - This message is from the Pentax-Discuss Mail List.
