Looking for wiring connectors for 1800ES turn signals 1800

Hi Everybody!

I'm fixing the wiring in my '73 ES, and the black plastic connectors that hook my front turn signal / parking lights to the main harness are worn out on one side and melted on the other. Would any of you know a source for these parts, or part numbers? There are no part numbers on them.

Thanks!

    Looking for wiring connectors for 1800ES turn signals 1800

    I am repairing the wiring to the lights on my '54 Chevy by running a new soldered wire to a spot where I can fetch them.

    Then I install female un-insulated spade connectors, crimped and soldered to both wires.

    I join them with a clear plastic encased double male spade connector.

    That way I can check the bulb without taking the fixture apart and I can see any corrosion.

    These connectors were used in my '68 VW - they even make two to one connectors.

    Fran,
    Have you figured out why they melted ?

      John;

      Melted electrical connectors, unless subjected to an external heat source (like an under-hood fire) are inevitably a result of an in-line resistance cause by corrosion or looseness or some combination of the two, resulting in heating due to (ohms Law derivative) I2R. Where I is the current in the circuit, squared, times the in-line resistance (which should have ideally been MUCH lower). Since there was no report of a fire, or fuse blowing (due to excessive current, more than normal) I can reasonably make this deduction...

      My advice to Fran is to replace damaged connector (and the heat-damaged areas are the forensic evidence and clue as to the precise location of heat-source/poor connection!), properly crimping terminals onto wires (using ACZP on stripped wires to create the next best thing to a soldered Gas-Tight-Joint (if it was me, I'd solder newly stripped wire ends into the pins!), and remate the connector (if a two part separable type) with ACZP on mating surfaces.

      Connectors shown on ES Wiring Diagram ( http://www.sw-em.com/1800ES%20Wiring%20Diagram.jpg ) are not like the Hex Conns used on the 122, but info here might be useful: http://www.sw-em.com/voltage_drop_in_headlights_power_in_hex_connector.htm

      Cheers

        Yep.

        Wish I had a dollar for every time I've seen melted connector housings blamed on under-engineered relays, hot light bulbs, excessive current consumption, aging fuel pumps -- you name it -- on the car boards.

        Still I'd want to see the examples before passing judgment.

          Art; Agreed...I'd also like to see some detailed pictures...

            Hi Ron!

            I wish I had more pictures of the problem before I fixed it, but since replacing the connectors I haven't had any trouble.

            I didn't end up using the new plastic connectors, since I put it together in a slightly non-stock (and reversible!) mod. I found a set of side marker lights at the junkyard and modified them for two-filament bulbs, so now my side running lights also act as turn signals. Not a flashy mod, but I'm using it as a daily driver and can always put the original markers back on. So far, no problems, but that could be because I've been slowly going through all my car's wiring, cleaning it up, and I think it was just a long time since everything got a good check-up and cleaning. Seems like a lot of spade connectors had become worn and were hanging on by a thread.

      It's not abnormal to see those plastic connectors get distorted over time.

      I think the heat in engine bay of a fuel injected 1800 and the proximity to the radiator that cause them to distort and get brittle.

      IIRC, I sold some new ones to Fran along with some of the special connectors 1 of the times he was at my shop.

      I get them from Volvo, but they aren't black and are possibly made of a different material as they are translucent. I won't know for 10 or 20 years if they hold up better.
