Continued indicator electrickery woes

Cornishdefender · 2024-12-24T14:41:52+0000

Afternoon
Continuing on from previous thread re our wiring issue - given we had got everything working ie indicators flashing as they should, hazard flashing as they should, dash lights illumniating as they should (but without satisfactorily finding an actual problem + obvious solution) I rewrapped the LH front loom, yesterday I put everything back together at the front of the vehicle.
So today went to test again in the barn before we were going to take Landy out on the road for a test run to check over a better distance before putting all the dash etc back together, RH indicator AOK with dash light, Hazards AOK but no dash light..... AND now when indicating Left, ALL indicators come on (though slightly dim) and dash light is as faint as faint can be.
Getting very p1ssed off and frustrated.

Anyhoo, any pointers would be much appreciated - and Nadelik lowen! (Happy Christmas

Its an earth issue, but where?

Did everything work before you "rewrapped" the loom?

Yes - have unwrapped the new loom tape and retested - still the same. But I now need to unwrap the electrical tape that I wrapped around the cores of the loom and retest. Just cannot see how wrapping could have caused the problem, except that given that was the last thing I did then it points towards that. But how....?

I dont know.

But leave it unwrapped for a while.
I still think its an earth issue. either at the lights or dash.

Electrical tape be the work of the devil!

Everything now completely unwrapped, cores all nicely separtated. Issue still exists......
Yes I used the Red Wolf tape as the outer wrap.

Going to leave it all unwrapped until we've solved it - or resort to an auto electrician.....

Are any of these lamps LED's ?

Cornishdefender · 2024-12-24T17:45:09+0000

Yes - the indicators were changed to LEDs about 4 years ago.

Is there a resistor any where? Early motors need 1 as the dash won’t flash & they don’t show in the dash.

When hazards are switched on the trailer light would flash on dash.(& switch if the bulb works)

Put a bulb in the indicator circuit & try again

The Durite load/ballast resistors work well, had issues on trailers with pulsing indicators, and trucks with fast acting repeaters, other tucks with indicators staying on dimly, all solved with the resistors, ps 12v ones do not last long on 24v systems cough cough!

Put it back original

Hi - without the LED indicators plugged in, with a normal bulb repeater plugged in the circuit, still get the same issue.
As said we've had the LEDs in place for 4 years or longer, no resistor was installed, we have had no problem up until this all started.
The RH circuit works fine - Dash light comes on as it should, LED indicator and normal bulb in repeater.
Problem comes when the LH indicator is actioned
Landy is 12v system

Could it be a faulty led then?
Have you got side repeaters as LEDs?
If you put a filament bulb instead of the faulty indicator does it work?
( just ruling out faults)
Thanks

If the LED was faulty wouldn’t that show up with the hazard activation? At the moment hazards work ( normal light level) the issue only happens when left turn is selected on the stalk.
Don’t think we have the original indicators - though might be on a dusty shelf somewhere- will check tomorrow.
Thanks
