A few problems... to say the least

[dstrykr77]

Just a few of the problems Im having in which I would greatly appreciate any suggestions on how to correct them.

Problem #1, I recently bypassed the centrifugal mechanisms for the table and sweep motors on one lane with potential relays. It worked great for about a frame and a half then it started to interlock. A few days later another bowling center was kind enough to lend us a STSW, at least thats what I think its called, and I installed it on the sweep motor, bypassing the potential relay, since thats where the problem is. But its still drifting, and really, really bad.

Problem #2, another lane will not respond to any cycle command, not from the MP chassis, the ball sensors, or the back end control box.

I guess I should let yall know the type of machines Im working with here. They are the good ol AMF 82/70's

#1 could be either a really loose gearbox on the sweep,toasty C1 pins/sockets,bad NC contactor for the sweep in the MP or weak capacitors for the sweep.
#2 Can be a bad M1 in your chassis,or the machine could be stuck in instructomat,you can isolate that by unplugging the A&MC plug and jumping out the pins to turn on the machine bypassing the front desk,You would need a short wire with 2 male C pins and plug into the center row of sockets until it fires up.DO UNPLUG THE SWEEP AND TABLE MOTORS FIRST SO THAT YOU DO NOT GET RUN OVER BY A SWEEP THAT HAS BEEN WAITING TO GO FOR 2 DAYS.

With problem #2, check your sweep cam levers and micro switches, at a centre I was helping out at we had almost the same problem, trying to think back from memory the the stop screw on the SB was way too far out, most were not correct either, once we got screws right etc all was good again...

Thanks for the input yall. It turns out it was a bad M1 in the chassis for one of the problems, the other I solved by going back to a mechanical centrifugal for the sweep. Still gets a slight drift after it warms up though. Maybe its time to take a look at the gearbox in depth.

Problem 2 I have that problem machine thinks it is in stand alone or practice shadow mode spent days i remember talking to a tech testing and replaceing just about everything then he told me to push down on sweep reverse and sweep run having sweep go through a cycle back up to 0 then he asked me to push cycle and bam that was it. Something that simple lol. just throwing that out there as a option good luck.

On the subject of chassis relays, it's always a good point to start with changing all with known good spares when strange electrical problems occur. A good example of this, unrelated to the pinspotter itself, front ball returns not firing up - caused by M1?... when the rest of the pinspotter operates fine.

Drifting motors are most commonly caused by C1 pins. I would eliminate these before moving onto anything else. Change ALL C1 pins (normally machine side plug) related to that motor.

Not related, but if you leave your spare chassis on top of the machines, I put the spares on every couple months. Sometimes the vibrations and such can cause issues. Also the pinchaser that does'nt write everything down may have changed it for a reason and left you a cluster f%$#.
