  • 58 Work light
  • I am repairing the work light on the 58 861 I'm restoring. The original bulb works but there is no ground from the bulb socket to the light housing. Does anyone have a picture showing how the socket was grounded to the housing or where?

    Thanks.

  • The OEM Ford 8N-15500 Implement Lamp used a socket with a bayonet style bulb soldered onto the reflector. It fastened into the socket and all metal contacts were your ground -remember POSITIVE GROUND meant any metal surface was ground. It was all part of the 6V/POS GRN system. You only needed one wire to power it. The worklight had the special frosted lamp or dimpled lens lamp. The shell had an ON/OFF switch on the back, the socket inside with one wire to one switch connector and the other switch terminal wire (power) going thru the hollow mounting bolt to the light harness. If you have a newer sealed beam lamp, you will have to get creative and run some separate wires inside, one to a ground. If you have a CM HALL made lamp, the mounting bolt is secured with a holding strip screwed on. You can use that to ground. The only other supplier was FORD and they did not have the bolt holding strip. Carpenter sells all the parts for the work lamp including exact repoops of the entire assembly. Here are some pix if it'll help ya...

  • Thanks for replying so quickly Tim. I've posted photos of what I've got. Bulb works, replaced the switch. There's no ground. Bulb is insulated from housing. I was thinking the socket needed to be grounded to the housing somehow.

  • That's it Mike. You have all the parts. Lamp bulb inserts into spring loaded socket and locks in with a twist. The wire end bullet connector from socket connects to other terminal on switch. The wire from switch feeding thru the hollow mounting bolt will then connect to the wire feed from light switch on dash for your power. This is the OEM 6V/POS GRN system. Now, if you are having issues with getting no power, here's a little trick I do with my worklights after I blast and paint them. Take a piece of sandpaper and gently remove the paint on the housing where the switch mounts to on the inside of the shell. This will ensure a good electrical ground. Then take the sandpaper and go on the inside of the bezel where the spring clips will go to secure the lamp in place. Sand the paint away under the lip of the bezel to bare metal to also ensure a good ground from clips to lamp shell. One last thing I do is sand the fender mounting cup a bit where the lamp housing fits into. I also will take a rat-tail file and get the fender bracket bolt holes to bare metal as well -all to ensure a good ground. It looks like you have a CM HALL made worklight. There will be their stamped diamond logo on the outer shell by the switch. Says: "CM HALL LAMP CO. DETROIT MICH USA"

  • Re: 58 Work light
  • I take my last comment back. It appears that the sealed bulb has a metal ring around its perimiters where it fits inside the retaining ring. I'm gonna sand the perimeter and spots along the retaining ring and housing/shell. I out to be able to get continuity between the metal ring at the perimeter of the bulb and bayonet post on the back.

    Where are your markings on the shell? I picked up this tractor from an old mechanic. Mechanically sound and not alot of rehab. The work like could be a replacement as it has no markings.

  • Re: 58 Work light
  • Mike -yes, the lamp reflector is metal. The bulb base soldered in is also metal, and the socket is metal as well. Sand the lip underside of the bezel like I said, not the lamp base edges -no need to do that. Sand the underside of the lamp housing where the switch mounts for a good ground. When the socket is twisted on to the bulb bayonet end, it makes the ground automatically to any and all metal parts. The CM HALL logo marking is on the outside right by the switch. Often many coats of paint will hide it. Hold it to a good light and angle it so and you might see it. As I said earlier, only FORD and CM HALL made the implement lamps. The only difference is FORD lamps had no wire retaining clip on the hollow bolt. CM HALL added one and their logo. NOBODY else made the original worklights back then. Today, only Dennis Carpenter is licensed to repop them exact-as-original. Every part supplier on the planet buys his and marks them up and resells them too. I wouldn't worry about the markings, I have no doubt yours is an original HALL. Get it working first. If you get totally stumped, you can send it to me and will get it working correctly. No charge, you pay shipping, my email is open.

  • Re: 58 Work light
  • So how does the ground complete the circuit? The sealed bulb doesn't have any metallic surface at its perimeter interface with the housing / shell to complete the circuit.

  • Re: 58 Work light
  • Sure it does. The base of the bulb is metal. The end of the metal socket has the wire with a tab thru it for the HOT wire to contact the bulb end point and the bulb housing, metal, and socket complete the circuit with a ground. I always test my lamp assemblies with a 6VOLT Dry Cell battery on the bench/kitchen table to be certain all connections are being made before I assemble the lamp itself.

  • Re: 58 Work light
  • Done and done. Thanks Tim. I cleaned the rim of the bulb with a fine brush on my drill, same with the retaining ring and shell. I've got continuity from the bulb to the socket and from the fender mounting bolt to the retaining screw that holds the retainer ring onto the shell. That should do it. I'll test it on a battery before mounting it.

    Thanks again.

  • Re: 58 Work light
  • anybody know where to get the reflector re-silvered? Bet it would help a lot with light output, but cost is going to be more than the light is worth?

  • EASTWOOD PRODUCTS sells a powder coat, "Extreme Chrome Bonded", p/n 15999 that may be a low cost alternative.

  • Krylon sells an aluminum flake spray that would likely work.

  • Re: 58 Work light
  • I thought we had a discussion on this a few years ago but couldn't find anything archived. I do know resilvering isn't cheap. Some mentioned chrome too but that is also a special process. You need a certain substrate of metal for chrome to adhere to. Others used a 'chrome-like' paint. I did find these places:

    1. www.queencityplating.com Queen City Plating 425-315-1992 (Washington)
    2. www.frankfordplatinginc.com Frankford Plating, Inc (Pennsylvania)
    3. carsrule@embarqmail.com Craig Riker 419-290-4442 (Ohio)
    4.www.nu-chrome.com Nu-Chrome (Massachusetts)
    5. No known website: Chidgey and Sons 619-441-2505 (California)
    6. No known website: Uvira Inc. 541-956-6880 (Oregon)

    I suspect nobody is going to be low-priced. Eastwood may have reflective paint. I have been playing around with the Implement Lamp reflector for years trying to develop a method of removing the old burnt out bulbs and resoldering a new one in. That part isn't the problem. The trick is to get the glass lens removed and back on without breaking it. It is crimped on and there is a rubber seal between it and the reflector base.

  • Re: 58 Work light
  • Both rear end lights illuminated and installed. Charging the battery tonight and hopefully will start him tomorrow morning. With any luck, I'll be installing the fenders and hood tomorrow to complete the project.

    Thanks! Happy and Safe New Years Eve.
