turn signal help please, for the electically in-experienced.. Options

[MrHyde]

Background:
The PO of my 73' 2.0L said that he never actually drove the car. He picked it up to restore and then got more involved with his MG's ( he has a sweet MGB with a mustang drivetrain in it , and a couple more under covers) .. anyways.. the turn signals dont work.. in the glove box i found an extra relay socket, and a 4 prong relay... hanging out under the fuse board is another of the same socket I found in the glove box.. I'm assuming that some PO wired this thing in to get the turn signals working.. the signal lights all come on when I turn the headlights on ( tail lights AND all the turn signals ) when fliping the turn signal switch, nothing happens.. no dash lights.. no flashing...

question...
I've never really needed to use a multimeter before, so i'm totally inexperienced with this.. I want to know how to find out if this socket is infact for the turn signals ( so I can just get a turn signal relay ) or find out where to check the wiring with the multimeter to see where the disconnect is happening..


Since My shoulder is out of commission right now, I cant do any heavy work at all, but testing a circut with a multimeter is doable. I've downloaded a couple wiring diagrams, but it all looks a bit greek to me right now...

Thanks in advance for the help !

my 1972 car has the problem of both directional indicator lights in the tach flashing together regardless of which direction I want to go.

so disconnect the bridged blue/white wires and tape them up, and connect the lamp socket spades to ground?

thanks

are you saying to connect the blue/white wires to ground?

This problem is caused by a failure of the secondary relay contact in the flasher. You can replace the flasher or make the change to the wires.

If you change the wires, yes, connect the common connection of the lamps to ground. Cut and tape the blue/white wire to the relay. Then reverse the other wires on the lamps. Left wire to the right lamp and right wire to the left lamp. I made this change to the flasher in my '71.
