Now it is quite common that trailer wiring faults or excessive trailer current draw leads to a blown hazard light fuse and hence to the "Tokyo by night" dashboard
.
On the Gen 3 the alternator voltage signal (the signal that the voltage regulator uses as feedback to determine the alternator's output voltage) is sensed externally. In fact it is sensed from the hazard light circuit. Unfortunately that means that a burnt out fuse in the hazard light circuit leads to the alternator voltage regulator losing its control feedback signal. The result is that the alternator output voltage rises above the maximum allowable value of 14.4V and the dashboard lights up like a Christmas tree as various control ECUs sense the over-voltage.

Hi, your post is very interesting, thanks for sharing your experience.
Do you perhaps know where I am able to source an after market regulator for a Gen 3 Pajero- I have a 2005 petrol 3.8.
Cheers
