Foul Cycle

[tenthframe]

I have 5 board converted omega teks SS chassis with elco plug to the masking unit. I had a lane (lane 1) today that every time the ladies bowled the foul light and buzzer went off at the line but never showed on the masking unit nor did the machine go thru a foul cycle. So after I fixed the out of adjustment reflector at the line I moved to the machine to figure out why it wasn't going thru a foul cycle. Swapped chassis and still no light on mask or foul cycle. I've double checked all connections both upfront and in the AMC box and all good, put working light bulbs in the mask at the foul light and still nothing. So my question is do I have 2 PC boards with no foul cycle, or is there a bad connection in the elco plug that would cause the machine to not go thru a foul cycle?

Have someone step on foulline and check voltage at AMC, this will narrow it down.

If the chassis gets a foul signal it should run a foul cycle even if there is no indication on the mask. If the foul connection is good at the foul light and the a&mc box, then it could have a problem after that between the a&mc box, a&mc plug, and where it enters the chassis. To completely eliminate the boards take a board from a lane with a VERIFIED WORKING FOUL CYCLE and put it in this one. If then there is no foul cycle then the chassis is not getting the signal. If it runs a foul cycle and there is no foul indication on the mask (and the lights do work) then check the elco plug- foul pins. Foul is going to enter the chassis through the C2A plug, at 17d, bottom row middle pin...

Have you verified output to the pinsetters at the Foul Unit Itself? Type of Foul Lights in play here would help.

With foul units I prefer to check voltage instead of continuity. Do like Jeff says and check for voltage at the A&MC box, then work back toward C2A. With the old Radaray lights we have, there's supposed to be constant voltage present, and it's a drop in voltage that signals the chassis to throw a foul. Not sure if it's the same for stuff built after the Flood. Maybe you could get your meter on the A&MC terminals and then have someone step in the beam, simulating a foul, and see what happens to the voltage.

Some of the AMF infrared foullights have 2 fuses in the unit to send a signal to the pit. With a bad fuse all works well up front but no signal is sent to the pit.

I didn't have a whole lot of time yesterday to give this the full work over so I will give it the works today. I have AMF Radaray units installed back in 2006. All connections in the AMC box were checked for tightness I didn't check for voltage so I guess I will start there and work to the C2A plug. Thanks for the ideas fellas.

On the output terminal strip of the RR unit, check for 12VAC to each pinsetter. As been mentioned before, if no output there, check the fuses. They will blow if there's a short on the output run.

It was a fuse, its been so long since I had put those in and have had zero to do with them since I didn't even give it a thought that there were fuses on the board in the units. Thats what I like about Bowl Tech, I never think obvious and everyone on here gives me the obvious.
