Know how machine runs for a few minutes after you turn it off up front before powering off, well I have a chassis that does not ever turn the machine off. Does anyone know what the part is on the solid state chassis that controls this? Would like to attempt to fix this myself instead of sending it off to get repaired. Thanks

Take a peek at the back end motor contacts, they may have fused together.Jerry Smith

Re: 8270 SS Chassis
Know it is in the chassis because when we put on our spare chassis the machine powers off. Problem moves with chassis...Comment

Re: 8270 SS Chassis
mwillard,
What jerjag was referring to is in the chassis. Your BE relay is mounted to the side of the chassis. You can refer to your manual of its location if you have one.
Also it could be your time delay module is toast. It is located in the same vicinity as the BE relay.
However, try jerjags suggestion first since this is usually the obvious problem and you can see the contacts stuck together. If you don’t have a manual, post back and I’ll try to describe the components to you.

Re: 8270 SS Chassis
Yea... BE contacts fused is the usual cause.
To find out, take the butt of a screwdriver, and firmly tap the chassis in the area of the BEM relay. If you get a little spark and the motor shuts off, there's your problem. Disconnect the power to the machine, burnish the contacts, good as new.
Time delay (unless it's solid state), reacts the same way. The TD is a small, flat, white or tan box with 4 wires coming off of it, that's mounted to the wall of the chassis. The unit is thermally operated, so it can stick, too. You can diagnose it with the 'tap' method, but you can't clean the contacts in it... just replace it.
Take a look at the M relay, too... M controls the BEM relay, and starts the time delay when it opens on machine shutdown. A sticky or burned contact there will cause a run-on backend.<span style="font-style: italic">Educatio est omnium efficacissima forma rebellionis</span>Comment

Re: 8270 SS Chassis
Another easy way to narrow it down is when the B.E keeps running, check for ball lights on the masking unit, if they're off and the pit is running your B.E. relay is sticking, if the lights are still on it's either your M relay or thermal time delay (H relay as it's called). We just had one go not long ago but usually the problem is the pit relay as stated earlier

Re: 8270 SS Chassis
Triac, do you have the part number for this BE relay?Comment

Re: 8270 SS Chassis
B.E. relay # 000-025-863 If the problem is in this relay, you should be able to switch the wires around and use the other side... [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img] it's # 23 in below pic...If at first you don't succeed, try, try, again. Then quit.

Re: 8270 SS Chassis
If you are talking about what I think you are, Call AMF and ask for Carl tell him what's it is doing. There is a wire on the plug in the chassie that needs to be switched. I can't remember the number right off the top of my head. I had the same problem. Good luck.I might not be as good as I once was, but I'm as good once as I was ever was. http://www.bowltech.com/forums/impor...2012/smile.gifComment
