Indicator relay
« on: October 10, 2017, 03:14:44 PM »
1978 400/4

Having a problem with the indicators folks. LH side works fine RH side front only comes on but does not flash and rear does not come on at all. Is this a relay fault or something else? I've checked the wiring and it looks ok and bulb is fine.

any help gratefully recieved as electrics are on a par with algebra for me......

NO! Relay fault usually means lamps either don't come on at all, or come on and don't flash. Have you checked/changed the bulb in the one not coming on? Try a new bulb first, and check the bulb holder is clean and not rusty, and also the little stud thingy that contacts the bottom of the bulb is clean, if in doubt, give it a gentle scrape with a screwdriver to make sure it is clean. If a new bulb/cleaning doesn't cure it, it's time to check the earth and wiring to the indicator in question.
If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

If changing the bulb/ cleaning doesn't sort it let us know, we can talk you through checking the wiring/earths.

Do you have a multimeter.. ?

You can swap the wires to see if the circuit causes the same issues on the faulty indicator then you know if you have a working indicator and then you can trace backwards.

Sounds like a fault with the rear right bulb / holder / wiring / earth return.
Where's that 10mm socket got to?
