My headlight fuse keeps blowing. The headlights are good but the fuse keeps blowing. I tested them in bothsides. I tested the fuse with know lightbulb installed and it does not blow the fuse.
Re: My headlight fuse keeps blowing. The headlights are...
Have you tested the amps being drawn with all bulbs in the circuit. This can be done easily by the DIY with an amp gauge and a few feet of wire. compare the result to the fuse amperage.
My 2000 Boxster S continues to suffer the same A7 (30AMP) fuse issue; consistently blowing everytime I turn on my FOG LIGHTS. ALL H7 bulbs (12v 55W) have been replaced, but that hasn't prevented the problem form recurring.

use the process of elimination, disconnect both headlights at the bulb and put another fuse in it and see if it blows. if the fuse blows without the headlights plugged in then its the wiring to the bulbs. if the fuse doesn't blow while the headlights aren't plugged in try plugging the lights in one at a time to see which headlight or socket is shorted. possibly corrosion at body to ground connections near the headlights, you may not see the corrosion, remove the ground wires and sand those ground wires down..
You have a short circuit somewhere in the wiring. Either a cut or bare wire. If not, the headlamp is causing the short. Last resort, use a higher amp fuse (but this may compromise wiring system).
You have a short somewhere in the headlight wiring. I would start by unplugging the headlights and see if it still blows. If so then you might need to trace the wiring back (with the negative battery unplugged) and find where the wires are touching. If it doesn't blow with the headlights unplugged then you should just need to replace the headlights.
THERE ARE 2 FUSE BOXES, 1 UNDER THE HOOD & 1 INSIDE THE CAR. TURN ON IGNITION SWITCH TEST EACH FUSE WITH A GOOD FUSE TESTER. FUSES CAN BE TESTED WITHOUT REMOVING THE FUSE FROM THE FUSE BOX. THERE ARE TEST POINTS ON EACH FUSE FACING OUT. POWER ON ONE SIDE OF THE FUSE, FUSE IS BAD. POWER ON BOTH SIDES OF THE FUSE IT'S O.K.
The positive wire in the headlight circuit is shorted to ground someplace, you have to check the wire by following it from where it connects to the headlight back to the switch and then to the fuse block
Are you absolutely positive you are installing the correct amp fuse ?
I think headlights on Subaru's run thru a relay, which could be bad.
Here's a how-to that may help.
Without knowing what fuse 24 goes to, what stops working when it blows?? Try everything. Headlights, 4-way flasher, anything you can think of while some one watches the lights fans etc. Once you know what is blowing the fuse, you can come back and ask a better question. Good Luck.
hi take the fuse out replace with a temparary test light turn your headlights on if there is a short the light will light up so what you need to do now is disconnect the headlights one at a time until test light goes out when testlight goes out you know this is the faulty headlight if the test light stays on disconnect lightswitch connecter see if testlight goes out if so replace switch if it stays on find headlight relay remove it see if test light stays on if it does then there is a short in the wiring which is very rare yates210456
