Hello Macenorman,
I take it that your name is Norman.
I would check out the Search Unit for sticking pins and also check out the Stop Plate assembly for dry joints on the track (slip rings) on the back of the assembly, also check the switches that they are adjusted correctly, personally I have never found the switches to be faulty on Rowe Ami jukeboxes.
Regards
Alan
