    Does anyone know of a place that sells all the pieces needed to rewire a par can in one kit or something like that?

    There have been a few post on this in the past. I'd start there.

    Yea, start there. In New York, there must be at least 50 places including the manufacturer.

    the manufacturer is the problem, Lee Colortran International is not in existance as far as I can find out, and leviton is virtually no help for anything made before the acquisition.

    You can still get most older Colortran parts from Leviton/Colortran - at least I still do on 20 year old cyc lights. In fact I get these parts from my electrical supply house instead of thru a theater supply. This given my electrical supply has a sales person specifically dealing with the entertainment end.

    I admit dealing with Colortran/Leviton/NSI since the buy out is a little more difficult or at least complex for vendors. The place I work for instance has had an account with NSI since before the buy out. While it might have at one point meant I could get Colortran parts due to this account, much less I could buy Leviton direct now, it's not the case any longer. This as opposed to the Advanced Devices (Bates) stage pin plug account once bought out by Mancuro enables me to buy direct the Mancuro line. This often is the case with other buy outs, but in the case with the Leviton one, it is complex.

    If you are having problems in having tried this electrical supply and theater supply means or at least the sales people you have dealt with in putting the proper amount of effort in failed, TMB would probably be the best place to contact as they are in your area and in many ways specialize in solving problems like this. Believe I have also gotten this brand of part thru them.

    What parts specifically are you trying to replace?

    all the leads and the ceramic lampholder(somebody closed the wires in the cover, and now I have exposed wiring waiting to kill the next person who focuses it while it's on)

    Take a photo of it, there might be a cheaper solution in repairing it if the conductors are in good shape and only the insulation is abrazed or cut. This given the lamp base itself is in decent condition - not broken and has sufficient tension to lift a lamp with it.

    Otherwise if just the lamp base with whip or tails depending upon style, that's standardized parts and you don't need to shop from any one brand. Look to other postings in me recommending the Sylvania brand with aluminum frame around it to protect against breaking. Lots of past info from many sources on PAR can wiring.

    the connectors and two of the leads are fine, but the other lead is stripped of insulation in a couple of places.

    Instead of replacing all the wiring,could I just use heat resistant shrink wrap to cover the exposed wiring?

    I don't think that will comply with your code. Whilst the heat shrink will cover the exposed cable, it is not rated as a replacement for the insulation that has flaked off. Besides, if the cable is damaged in one part, it is most likely that it will fail in other parts as well. Thus replacing the wire will be your best bet.

    As Ship suggested, post some pictures so we can see exactly what it is that you are referring to and so that others on this site will also be able to benefit from this topic.

    it didn't really fail, someone made it fail by shutting it in the cover

    Post the pics so that we can see the full extent of the damage. Split or "cut" insulation is different to stripped wires. Too many varioations or interpritations can be attached to such words.

    I took it that your wire had pieces of insulation flaked off and missing.

    there is an area about 2cm in length that has been rubbing against the cover and is now somewhat exposed

    High temperature heat shrink is not flexible. It's only servicable use in in covering high temperature butt splices as needed when attaching the lamp base to a cable whip as opposed to using the leads of the lamp base in a fiberglass sleeve in going to the plug.

    Problem it would seem both Mayhem and I have is that we don't really understand by your words which conductor it is that is exposed, which of the above two systems is in use, or to what extent the damage is to which part in recommending a solution of replacement. In most all conditions, replacement will be necessary unless the ground in which case it's possible you can possibly fiberglass electrical tape it due to it being a ground and not mattering if it touches the frame as it does already.

    On the other hand, given you had enough slack that some of the conductors got caught in the cap, it might be possible to high temperature butt splice the thing and either cover the splice in either the high temperature tape or use the high temperature heat shrink. This is possible dependant upon the general condition of the cable in question that I would want to look at.

    Short of this, I recommend you either replace all infected components, or take it to a qualified service person to have a look at it. Just can't confirm such a thing anyway as what to do.

    The chances are pretty good it's not a fixture that Colortran made. They really only ever made Ellipsoidals and Fresnels. Pretty much anything else that had a Lee or Colortran logo was someone elses.

    Meaning a Par was probably either Altman or L&E.

    Doesn't matter actually as either will take the same socket.

    What's usually done is to buy a socket with leads. Production Advantage (as well as others) sell a Mogul End Prong, 48" lead socket - #58-007 for $15 or so.

    You only need to replace the socket and wiring, removing ONLY that from the can - leave the ground wire connected to the can and connector. It's common to see a plastic strain relief - know as a keyless strain relief and commonly sold under the Heyco name. You can get this off with a pair of ViceGrips or pliers (or an expensive Heyco tool - $50), just be nice cause you want to re-use it. If the fiberglass outer jacket for the instrument leads is frayed, PA can sell you individual lengths, pre-cut as well. Heyco bushings also if needed.

    It's an L&E,and the plug is not molded.The plug is just a regular replaceable Twist-Lock. I do not have a digital camera or a scanner that works well enough to post the photos.
