MK1 turn signal problem

1966 Austin Cooper S

Just started testing electrical.

Running/Parking lights front and rear work just fine.

LH turn signals (front and rear) blink OK.
Indicator on end of stalk blinks just fine as well.

RH turn signals do not work at all.
No lights come on at all,

What is likely problem and fix?

Left hand blinkers working means that the blinker can is good as is the ignition wiring to it.

Possible faults could be:
indicator switch faulty
Wiring connections from indicator switch to lamp bases open (check 5 way bullet connector and bullet conections above grill)
Both globes and/or socket bases faulty

To fault find remove the Light green/brown and Green/White wires from 5 way connector(under steering column) and join them together. Make sure they are the wires that come from the loom not from the switch. If RH indicators work (ignition on) then the fault is in the indicator switch itself.

To echo what willy says, probably an earth fault.

Literally had the same issue last week.
Turned out to be the wiring connector underneath the dashboard from the wire that runs down the column.

Jiggle it about a little bit and try again to see if it is that.

Thats the 5way bullet connector mentioned!

Have a good look at the mounts for the shroud ....and if its not fitted look at the relationship between the fixed and moving parts of the indicator... The shroud doesn’t have to move much to prevent the arm from moving far enough to actually make a connection between the metal bit on the arm and the rivet on the base.

The moving contact is also fairly light and easilly bent so it just doesn’t touch when the arm is moved... If its an original switch the little rivet also gets worn and may not be making contact. General wear in the pivot can also stop the contacts meeting..

Cheers, Ian

Problem solved!

Problem:
LH flashers worked, RH flashers did not.
Green light on stalk not working.

Solution:
Green/White wire in 5 way connector was loose.


Thanks everyone.
