as per title was overtaking a truck the other night and lost all headlights i replaced a dodgy fuse thingy near the brake booster and got the right hand headlight going and fog lights to get home, now i thought i killed a ballast or bulb but when i chucked a new one in still nothing, checked the lh headlight fuse and every time (even with the lights off) it keeps blowing fuses, anybody else had this drama?? did a search but came up with everything else but this haha
Yup. Likely a short. Got a multimeter? Just going to have to circuit check sections I think. Start at the head light and work backwards.
if you can't resolve the issue.. you can buy a relay system for the hids http://www.ebay.com.au/sch/i.html?_...id+relay&_nkw=H3+hid+relay&_sacat=0&_from=R40 and just connect to the RH supply for the signal, the relay will draw direct from the battery and supply both L & R hids.
Ohh yeah Of course check the ballasts first, should be easy to swap the left and right. Good luck, I hate electrical gremlins if they can't be sorted quickly... they do my head in. LOL :zlove:
Fuses provide protection for the wiring circuits. If a fuse 'blows', it means it's doing its job, there is nothing dodgy about it. From your description, changing the dodgy fuse thingy near the brake booster, sounds like you have changed a fusible link. A fusible link is a primary circuit protection device, they are rated above the normal fuses protecting individual circuits. As the lh headlight fuse keeps blowing, there is likely to be a fault between the fuse & the headlight, it's possible the relay could be defective also. Time to get out the FSM & multimeter!
Try a light globe instead of the fuse. Replace the fuse that keeps blowing with a small 12volt globe and make the connecting wires long enough so you can see the globe while you are in the front of the car moving wires. Because there is a short somewhere and the circuit is ON then the test globe will light brightly. While wiggling the headlight wiring check the globe and when the short is removed the globe will go dim. If moving wires does not dim the test globe then start disconnecting the HID equipment until the globe dims. Whatever makes the globe dim is the cause of the short circuit. This will help pinpoint the cause of the short circuit. MichaelZ Good luck.
Don't agree.... The fuse is protecting the wiring from damage. Wouldn't it be abetter idea to use a multimeter? Set the meter on ohms, connect the black lead to ground & the red lead to the fuse, or you could remove the fuse, watch the meter while you fool around with the wires.
You could use Ohms. The globe test pin points the area. Of course a ohmmeter will also show the short but where is the short located? The globe in place of the fuse limits the maximum current that will flow in the short circuit to the globes current. It is safe. When you move the loom or wires you can locate the shorting area quickly. If the loom does not make the light dim then removing parts of the circuit will narrow the culprit. MichaelZ
its not the ballast or bulb, tested them already, when I get the chance ill give the loom a stir up with the test light in the fuse holder, if all else fails i'll wire in a relay off the right hand headlight wiring, was kinda keen to sort the factory gear rather than rewiring the front of the car, be more constant voltage if I did tho...........thanks for the replies guys !
The headlight globes are held in by grounded springs. Make sure the right one isn't contacting the globe contacts. Remove the connector from the right hand globe and see if you still blow fuses. If you have HIDs fitted, disconnect, and reconnect until a fuse blows. The last thing you connect will most probably be the problem.
