reb78 Posted July 19, 2020 Share Posted July 19, 2020 As above, my trailer tell tale for the indicators on the dash isn't working. The trailer lights ARE working and everything has normal bulbs not LEDs. Any ideas? Its a 1989 110. Quote Link to comment Share on other sites More sharing options...
western Posted July 19, 2020 Share Posted July 19, 2020 I assume you have replaced the trailer warning light bulb ? it's driven by the flasher unit, so maybe a fault in that item even though the rest works, thought I had the unit I removed from my 110 after changing to led indicators all round, I have found it, it's this unit in my reply photo in this thread https://forums.lr4x4.com/topic/100746-indicator-flasher-unit/ Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 19, 2020 Share Posted July 19, 2020 You need to check your flasher relay has the facility. Should have 4 pins on it. Quote Link to comment Share on other sites More sharing options...
reb78 Posted July 19, 2020 Author Share Posted July 19, 2020 Thanks chaps. The bulb definately works as the telltale trailer light triggers on for the first flash of the indicators with and without a trailer connected. I did replace the flasher relay last year. I cant remember if I have towed since then though! I replaced like for like though and the telltale definately flashed before that with the trailer indicators. It also flashes as it should with the hazards. Quote Link to comment Share on other sites More sharing options...
western Posted July 19, 2020 Share Posted July 19, 2020 Do you want to try my spare unit, if your in my area I can bring it across Monday afternoon. PM location details. Quote Link to comment Share on other sites More sharing options...
cackshifter Posted July 20, 2020 Share Posted July 20, 2020 I have the same issue. I think it's maybe because of voltage drop at the trailer bulbs insufficient current passes to make it think there is a bulb there. I know the obvious is find where the drop occurs but I have spent quite a while checking through - the fuse box under the dash was one place there was a bit of a problem, but not enough to stop it working. So what to do ? Maybe add another bulb/resistor in parallel on the trailer, or I think Boltonbits do an adjustable unit - I was planning to do the latter, as I think it's tested at MOT time if you have a 13 pin trailer plug (which I want to switch to as the 7 pin ones corrode & produce a voltage drop...)

reb78 Posted July 20, 2020 Author Share Posted July 20, 2020 Sorry Ralph, not been on today so only just seen this. Its a bit of a trek really so don't worry. Given the replies on here, I need to try the other trailer and see what that does - that could rule out the car and implicate the trailer. I am sure it was working at one point yesterday but stopped soon after I embarked on the journey.... Its a 7 pin plug so I might blast it with some electrical cleaner and see what that does... Will report back... Quote Link to comment Share on other sites More sharing options...
western Posted July 20, 2020 Share Posted July 20, 2020 That's OK, it's here if the trailer is not the culprit, Quote Link to comment Share on other sites More sharing options...
