This afternoon I was helping a mate fit a replacement exhaust to his '96 80-Series. We did zero electrical work other than disconnect the O2's and fit a hall sensor to the output of the alternator. The battery was removed to give it a top up charge - he experiences laboured starting's in the mornings but wasn't sure if he had battery issues or a charging issue. The truck was idling for a good 20 minutes as we checked the exhaust fitment. I turned on the headlights to show him the difference in alternator output with a load on the system. The lights came on and then both went out.
I ploughed through the wiring diagram looking for a common point of failure. After a few minutes I tested the bulbs and both were failed. New bulbs fitted and all is good.
That said I am no believer in coincidences. What could possibly cause both bulbs to blow? The 15 amp fuses were fine. What am I missing?
