    Machines are as-90

      Re: Electrical Problem

      You first want to look at the voltage on the coil of the motor start relay. If you have 24 volts, then change the relay. The coil is weak. If you don't have 24 volts, I would look at the front desk. I believe the AS-90's have an MIU. I'm not as familiar with the 90's as with the 80's. In Source Command, we had a silver box that turned the lanes on and off. It had a habit of burning the connectors on the back of the box. It developed resistance at the connectors which caused heat to build up which in turn caused more resistance and on and on until the connectors would start to melt. The higher resistance would prevent all of the voltage from reaching the motor start relay and from tme to time would not pull in. This could be what you are seeing. The first thing to do is to check the voltage at the coil of the motor start relay and see what you have.

      Another item to check if you do have 24 volts at the coil is if any wires are impeding the movement of the coil. Of course, this is for American A-2's. If you have Japanese, I would only believe the coil would be bad if you have 24 volts at the coil.

      Good luck...

        Ken,
        I posted on a thread a while back on voltage drop,on the motor start circuit.I will try to find it and post it.You need 24v at the motor start coil when the counter has it turned on,as Steve said.
        What type of pinsetters and what is the incomming voltage (115,208, or 220)

        I have seen centers that would have 26v at coil when they turned it on in the back, but it would drop down to 22v when turned on by the L.I.U. at frount desk.

        Later

          Rake sweeping out of time, and pin launching onto lane.

          I work on some nice old Brunswick A-2 pin setters. Most issues I've come across haven't been to problematic to figure out. But being I can't seem to get it to recreate the issue...
