Check the 9th position switch on the 100s reel for being to close and energizing the 1000 point latch in relay prematurely .
the 9th position switch works in conjunction with a normally open switch on the 100s relay . If that switch is to close and doesn’t open quick enough when relay coil releases that overlap in time might be enough to pulse the 1000 point relay.
