Talk Morgan Forums Thread Like Summary - Hazzard and rear light issue?

I wonder if any of you have encountered these issue's before and could share your wisdom?

1) Hazzard lights... My indicators work perfectly on all four corners, however I have noticed my Hazzard lights only blink on one side! Does the Hazzard have its own relay or is this likely to be a hazzard switch issue?

2) If I switch off the ignition and remove the key with the main light switch on, the rear tail light stays on until i turn off the light switch, i'm assuming that this is not normal?

Any Ideas?

I can confirm that the tail lights stay lit after the car is off if the switch is left on. I am not sure about the hazard relay.

If not the TSM, then it could be more of an old school electrical fault. The wires (and their insulation) to the rear lights are very thin and can be prone to chaffing and assorted shorts and open circuits where they go through the boot lid hinge.
Could be worth checking but it's worth setting aside longer than you expect to get in about them and getting everything fixed and back together.

Apologies for suspecting the TSM unit Biggle but it is notoriously unreliable. Applying a bit of logic pretty much the only component that would cause your issue are the diodes fitted to loom side contacts on the 12 pin instrument switch connector. Specifically pins 8 and 9. You haven't said as far as I can see which side is not working when hazards are selected but if its left check diode attached to pin 8 if right, diode attached to pin 9. These are needed to isolate left from right indicator feeds when hazards not in use and I suspect one has gone open circuit. Note polarity if replacing - the wiring diagram shows black marked end (cathode) connecting to each of above mentioned pins. The other ends go to a common pin on connector probably pin 6, but this will be obvious when viewing connector.

Impressed with your diagnosis Richard, as ever. I think you are the only person I know who can make any sense out of the circuit diagrams in the parts manual 😁.
