Thread: Odd indicator problem

Hi,
I bet you have a bull bar with repeater (extra) turn indicators. These add to the current draw. The increase is sensed and brings on the trailer dash lamp. All normal.

The bit about the disappearing dash lamps is possibly due to a poor connection in the dash area or a ground circuit. -- The current flow (from the outside and working part of the loom) through the local lamp and then to earth has found a poor connection. This causes a bit of heat. The resistance of the joint rises a bit and that reduces the current, so this part of the circuit effectively goes "open" and ceases to operate - no light.

Look for a loose/dirty joint in/ around dash to firewall? earth point.

Thanks for the reply- I'll pull out the binnacle and see whats there....

Hmm I don't have bullbar repeaters but I do have LED lights in the rear bar. I unplugged the LEDs to see if that was the problem but the situation does not change even if I unplug them. I can see though how the trailer light would come on with them connected though- current draw would be the same as with a trailer connected I suppose.

I noticed the dash trailer light on my '89 classic appearing when I turned my indicators on, but the indicator light was still working normally. The trailer light was flashing once every time I used the indicators.
It turned out to the be the flasher unit, which started doing all sorts of weird things not long after that, so for me it was a first sign of failing flasher unit.
After replacing the unit everything went back to normal.
Very easy fix, plugs in under the drivers side dash, I think the flasher was around $55 from memory.
I also took all the indicator bulbs out and cleaned the contacts with contact cleaner to make sure the current was getting through to the bulbs properly.
Hope this helps, Cheers, Pete.

AFAIK the trailer light is supposed to flash once when indicators turned on.

The 3 Rangies I have had have always done it, and my current one has done it for 10years without flasher can failure.

Phew, I thought I had a problem for a minute. Thanks PA .

Great, this is helpful I've been playing around with it this arvo after work and now, somehow, magically (as rovers seem to act) the hazards have started to work, and so has the interior light. It has been ****ing down rain lately so I'm guessing I have an earth problem somewhere. The hazards come up on the dash ok and work fine outside so I'll check out the flasher can see how that goes...

Thanks for the help!

The year of your RRC would help a lot with knowing which wiring diagram to consult.

cheers, DL
