Flashers - Gauges

    OK so a new issue. Flashers stopped working, both directions. When I put the right flasher on, it doesn't work but the temperature gauge and fuel gauge both go t0 zero. If I shut down and restart, the gauges work, try the right flasher (still doesn't work) and the gauges go to zero again.
    Flashers worked fine previously.
    Any ideas?

    Check your grounds. Each dash light and gauge is grounded. You must have something either off or loose.

    I didn't realize the gauges go dead when either right or left flasher is activated(flashers do not work)

    It would help to know what Series Alpine as the gauge system is different in Series III,IV and V from SI and SII.

    Series IV

    Gauges on SIV are powered from the "Voltage Stabilizer" or "Voltage Regulator "., ( not to be confused with the main Voltage Regulator used in the charging system). Something in the wiring for that stabilizer is incorrectly wired to the turn signal system. See this wiring diagram. If you have original wiring, with the original color wires, you can pretty easily follow the wiring to see what is mis-wired. :

    For just troubleshooting the gauges and turn signal circuits, you may find this SV diagram easier to follow. The wiring , including wire colors, for the turn signal and gauges is the same in both cars:

    s5_diagram.pdf (sunbeamalpine.org)

    I suspect that the wires connected to the socket for the silver flasher relay may be connected wrong. Verify that the green wire goes to the B terminal on the flasher unit, and the green / brown wire goes to the L terminal , and the green/ blue wire to the P terminal.

    In your original post on the thread you say "Flashers worked fine previously". What do you mean by "previously"? What did you change before they stopped working? Or did they work on one day and simply not worked the next day?

    To explain "previously":
    I have a 2.8l V6 that was overheating.
    Installed 2 7" electric fans through a new fuse box that had continuous power.
    Everything worked fine.
    Then decided I wanted the fuse box to get power only when ignition switch was on.
    Hooked up power source from "original" fuse box to get this.

    That's when the fight started..............................flashers didn't work and gauges died when I tried flashers.

    Just changing the source for the fans from constant to switched should not cause the problem you are seeing. Most likely you inadvertently switched some other wires while you were redoing the wires. I suggest doing the steps i suggested above.

    All wires were connected correctly
    Jiggled wires under dash................................everything started working................hmmmmmmmmmmmmmmmmmm...

    I had an issue with a ser5.... hit the turn signal and a horn would beep!!! Ended up being a bad ground with one of the headlights!!!
    That took a while to figure out!!!

    There are lots of ground wires behind the dash. Pretty easy to miss one that may not be tightly connected .
