2006 mitsubishi endeaver ECU goes out withing 500 miles of being replaced. has had 8 ECUs in 4 years and no high beam head lights when it goes out. What is cause?
when lights go dull it means either a bad earth / high resistance to current flow or the current for the lights is being diverted before it gets to the lights . What I mean is that there would be 12 volts at the power wire to the lights and very low voltage at the earth wire from the lights as the resistance of the bulb elements reduce the current flow . Now if there is a place that is draining off the 12 volts before it gets to the bulbs say to 7 volts then there is less current available to properly work the lights and they will be dull. A bad earth will effectively add extra lights into the circuit and increase the current flow as it is like hooking lights up in series(P ve to N-ve to pve to neg to pso to nev and so on instaed of adding lights in parallel ( all pve on one terminal and all Nve on the other . If you keep having troubles with the unit burning out then check the earth points and if you are running extra lights or lights with higher current draw ( example 65 watt bulbs to 125 watt bulbs ) with out running a relay in the circuit will cause problems as the unit is not designed for that sort of current draw.. The units will be good to start with but the killer will be too high a current draw through it from some of the faults I have outlined . BY using a multimeter and an amp meter in the circuits you may find the faulty bit
