    Hi Folks
    I have a '56 Willys CJ5. My front left turn signal wasn't working. I took apart the signal switch and pulled out a ton of mud, and put it back together. After that, the light in the signal switch stopped working, and all the signals decided to quit not long after.

    I tested the relay under the dash and it's clicking fine on both left and right turns. However, there's no juice getting to the front left turn signal light. I cleaned out the socket, thinking it might be a grounding issue with the single contact bulb, but it continued to not function.

    I tested the lead from the relay where it goes into the signal switch on the steering column, and my tester was flashing. So it would seem to me that the problem might be inside the signal switch. I actually bought a new bulb and put it inside the switch assembly, and it flashed for a while. I started up the jeep again, and the bulb inside the assembly no longer lights.

    It seems to me there must be some kind of short inside the assembly (Grote SAEQQC85). I checked the Grote turn signal wiring diagrams here:
    https://www.grote.com/wp-content/uploads/2017/09/Turn-signal-switch-wiring-diagram.pdf

    It didn't really help. Does anyone know if there's something within this assembly that I might need to take care of to remedy of this problem (or any other suggestions?)?
    With thanks,
    Tony

    Maybe not a short unless you are seeing smoke, more likely an open. These switches are finicky with old age, but can be cleaned up and re-habbed.

    Open it up carefully and don't lose any parts. There have been some good threads here on the rebuild. Try searching.

    And welcome! I also have a '56. My turn signals don't work...:oops: But everyone around here knows where I'm going.

    That's an interesting switch for sure--it has the connections, male spades, on the outside of the switch but it looks similar to a Signal stat 900 [which seems to be the other non-OEM switch most Jeepers use].

    I think you're going to have to go in for some minor surgery. Take pics along the way!

    Thanks PeteL,
    I'll open it up and see if there's something I can tighten up.
    My new bulb appears to have fried. Just not sure why.
    Will keep y'all posted.

    Welcome from Michigan, Tony. I have never seen the Grote turn signal, but Grote Lights and Accessories are in every auto parts store around here, I have Grote tail lights on my Jeep, they are a large supplier for trailer lights and automotive lighting, so I would think the turn signal would be good quality too. You probably just need to sort it all out, Good Luck.

    Is your '56 still six volt?

    No, it's been converted to 12 volt.

    Have a question. For what reason do you run your head lights through the turn signal switch?

    Could that be why your bulb burned out? 1956 was OEM six volt.

    Good question. I'm pretty sure my headlights do run thru the sig switch, but I'd have to verify that tomorrow.

    I don't know. It was working while I was test driving it, and it looks to be an old bulb. I just put in a 14.4 volt bulb and it seems to have burned out too. Just got in. Will be checking it in the morning.
