Came into house this AM, pindeck light on lane 9. I go to change it and the fixture is bent all to he77. So I pull the whole thing off, take it in the back and pull it apart. I took both ballast out so I could staighten fixture and then put it all back together. Reinstalled it on the machine, plugged it in turned it on works great. Turned the machine off, light still working great, so good it doesn't go off. I'm confused now. We use 2 ballast (1 for whitelight, 1 for blacklight) wired as such. 3 wire cord into fixture, ground to ground, one wire to ballasts, one wire out to 3 way switch, 2 wires back in, one to each ballast. I never undid any connections when I pulled it apart but now light won't turn off with machine. Whatzzzzzzzz upppppppp.

<font size="2" face="Verdana, Helvetica, sans-serif">If the machine went off. I would guess their is a bad ground in the fixture, since it was damaged. And might be getting feedback voltage. I assume it does go off if you remove power plug to the machine.Originally posted by RGP:

Re: Weirdest Thing
Yes, it does go off when unplgged. I reconnect ground when I reinstalled. Going in now, will update tonight.

Re: Weirdest Thing
A bad ground might do it, but there's one issue with that... if you're using the decklight receptacle at the front of the machine, it is switched through the chassis (via the M2 relay on the SS chassis if I remember right) to power the decklight. Turning off the machine is essentially the same as pulling the plug on the light fixture.
If you are using the SS chassis, check to make sure that the contacts on the relay didn't arc and weld themselves together.<span style="font-style: italic">Educatio est omnium efficacissima forma rebellionis</span>Comment

Re: Weirdest Thing
Good call G. I don't have much experience with chassis, but I went about it logically. I says to myself, "self, where is this power coming from". Traced wires through wireway to chassis. Switched out chassis, works fine. I'm not sure which chassis we have though. One large board with a lead to another smaller board. MP's I think, just not sure. Any idea's or tips would be helpful, otherwise I'll just have the boss drop it off at Stahls. Thanx to everyone for all the input.

Re: Weirdest Thing
Not sure what kind of chassis you have, but it sounds like you may have an SS chassis converted with an Omega-Tek MK70 board (Which has a large board with a heatsink on it, and has a bunch of wires leading to a smaller board). The MP chassis has a long, large board that plugs into a cardedge connector in the chassis... as far as I know, there are no wires that attach directly from the chassis to the board.
If it's an SS chassis, there will be 3 'icecube' relays socketed into it, to one side of the cardslots. Near to the bases of the relays, the steel baseplate will be stamped with the relay functions (M, M2, SP). The M relays are interchangeable, the SP relay is not. (Different coil voltages. SP is the middle relay.). You may want to try putting that chassis back up on the machine, then take a set of M relays from a machine that's working (or a known-good spare set) and swap out the relays. Pull out the mains supply line (RusselStoll) plug before reaching into a chassis... even when the machine is off, there are open contacts in the chassis that stay energized with supply voltage. The safest way to pretect against a 'case of the zoomies' is to disconnect the machine, swap the relays, and then reconnect the power.
Power up the machine and see if the chassis is working right. If it is, throw out the relays you removed from the offending chassis and replace them.<span style="font-style: italic">Educatio est omnium efficacissima forma rebellionis</span>Comment

Re: Weirdest Thing
YEP, if the relays are the orginal relays, kick 'em to the curb! I can't tell you how many times I have either smacked the OLD relays against the wall or drop kicked 'em into the feild behind many houses! 1960's relays and crappy sockets will drive ya nuts! It is well worth the investment to have at least a few new relays (complete sets) on hand. Heck, 30 or 40 years for a relay is pretty darned good, but it is time to "retire" them old guys!

Re: Weirdest Thing
G-(you are the)man! Another problem solved. Replaced relay and everything is great. Once again BT to the rescue. Thanx eveyone.

Re: Weirdest Thing
RGP: Glad it worked for ya! It's a good idea to keep at least 2 M/M2 relays handy, and a couple SP's as well. The M/M2 relays last quite a while, and it's normally the coils that burn up on them, since they pull closed when the machine is powered up, and don't open until the machine is turned off. The SP's are usually the ones that the contacts burn up in, sine they go through a lot more close/open cycles than the M's do (the SP fires every time the machine spots a rack).
