soutie Posted December 28, 2023 Share Posted December 28, 2023 I have a retrofitted Td5 dash in my 1989 110. The hazard switch does not have a plug and I did not note the wires position when I dismantled it 12 years ago for my rebuild. I have wired it as per the photo below. The switch now works and indicators flash when the ignition is off or on. However the indicators do not work. I have changed the indicator dash stalk as the plastic bit around the steering column was brocken. Could it be my wiring of the hazards that has caused this, or should I test with the old indicator switch to see if it is the new one that is playing up? If I move the light green wire from pin number 6 to 8 the indicators still work. The trailer light on the dash flashes using both pins when the switch is on. I tried this LG wire in place of the other one on pin 3 and it did not work, so think I have the wires in the correct places. DG is dark green so I could differentiate between that green and the other two wires. Quote Link to comment Share on other sites More sharing options...
Shep The Disco Posted December 28, 2023 Share Posted December 28, 2023 Wack on the old switch and see. Always good to try these things Quote Link to comment Share on other sites More sharing options...
soutie Posted December 29, 2023 Author Share Posted December 29, 2023 Put on the old switch today. Left hand indicators now working. Went back to the wiring diagram and hazards switch. All seemed to be correct there. I tested the old switch and on the left side wiring and the voltage switched between 0 and 12.3 volts. Then tested the right hand side, it was a constant 12.3 volts. Taking the dash apart I could see the green and white wire from the hazards switch going behind the instrument panel and into a loom with a bullet connector before it went in. The ligher green and white wire from the other side of thevplug from the indicator switch also going into another part of the loom. Thinking that there is a join in the middle that has pulled apart, I made a short length of wire with bullet connectors on it can connected it to the other side of the switch's plug. I then undid the single bullet plug connector on the dark green and white side of the loom. Put in a double connector and connected the old wires and my new length of wire. Now the right hand side indicators also worked. Some time over the next couple of days I will take the new indicator switch off and see why it is not working. If I can't get it to work I will replace it with the old one and make a bodge on the plastic bit that holds it to the steering column which is brocken. A bit disappointed that the new one is duff, but glad I found the issue with the wiring. The other thing that I found is if I moved the red wire from pin 4 to 8, then all the instrument lights flash when the hazards are on. So moved it back to pin 4. However when the lights are on the switch does not light up. Is there a bulb in this switch which should light up or not? Quote Link to comment Share on other sites More sharing options...
