      I just picked up a MOT 98 which has the battery negative wire just lying in the case disconnected. This is the unit with no circuit board and a vibrator. I was wondering if someone who has the same unit could look inside and tell me where the negative wire connects? I believe it connects to the pilot lamp but without a schematic would like to make sure.
      Thanks

        I would say yes since mine has a black and a green wire on the ground for the lamp.

            Thank you both for your replies. This is exactly what I need. Now I just need to wait for the new power supply.

              I use a 7.2 volt battery from a rc toy and charger usually less than $30.00.

                I’m pretty sure this was the 7.5V power supply I used.
