hello all.. last night I have been doing a lot of driving (~220km) then towards the end of my trip I switched on my highbeams and everything switched off.. Luckily when I turned off the highbeams the engine started and everything returned to normal. I repeated it again with the radio off, heater and fan off much to the same result. I gave it roughly 10 minutes then tried again and nothing happened.. I then got home turned off the engine and turned it back on and it started as normal I started the car this morning and all was working fine.. there was no struggling when I tried to start I was able to turn all the high drawing devices(radio fog lights and aircon) on (at idle) and nothing happened Does anybody have any idea what may have caused it? thanks
