Sounds like a short in the electrical system in your car.. that could have caused the globes to burn out in the first place... have you installed any electronic devices recently? or check all the wiring for any aftermarket devices such as turbo timer, CD player, Amp .etc.

Get an auto electrician to check it out

Cheers

Check all the engine earths and also the earth on the headlights, make sure there is no corrosion build up around these areas.

Did both headlights blow at the same time? or did only one go and then you decided to replace both?

Alternator could also be on its last legs, you need to see what the current jump is on the battery with a multimeter when you start the car to know if its dieing. You can check the alternator directly too but you still need to grab a multimeter. Check the earths first, also put the inerior light on and the A/C and see if it will die by using other items.

It sounds like your alternator. Best way to check it is to start your car and then disconnect one of the terminals from your battery. If the car turns off its your alternator but if it doesn't then its something else.

disconnecting the battery while engine is running is a risk to damage the alternator`s governor.

to check alternator just measure voltage @battery terminals, normal value is 12.3-12.8v with engine off and ~ 13.2-14.5v with engine on and healthy alternator.

hey thanks for the advice, my car has got a turbo timer fitted. and it looks like they have just spliced the wires and joined them. i will go check for suffecient voltage tonight or tommorrow and let you guys no what the problem is

[jtrb25]

hey i have checked my voltage and it all seems to be fine about 14.4-14.3 with car started and everything going flat out, lights and aircond. while i was looking over everythig i noticed that there was a steel rope kinda thing only small tht looks like it was connected to my catalytic, but no longer is. i reconnected it and ill see how that goes. anyone know what that is???

ps.. im not that crash hot with car electrics...

temperature sensor for the cat. if the cat gets too hot a dash light shows up to let you know.

shouldn't normally happen unless there's something wrong or you're driving it like it's stolen, but might as well have it plugged in since it's there!
