R32 Gtr Dash And Rear Light Fuse Keeps Blowing

[paulR32gtr]

Annoying problem, my R32 GTR dash and rear light fuse keeps blowing.

Pulled out the existing and swapped in a new 10A fuse, blew it straight away.

Anyone have any ideas as to what would cause this?

Would a short circuit somewhere cause this to happen?

My alarm was installed reasonably recently so there has been someone in there playing around with wires

Incidentally, I also noticed that for the starter signal fuse there is a 15A instead of the 10A on the diagram, and a 20A for the hazard lights instead of 10A.

Maybe replace the incorrect fuses with the correct ones.

I know this is a sh*t job but you may need to look at the connections for the alarm system. Maybe they left a wire naked and its touching the frame of the car, or something else.

Look for dodgy wiring, close up lose ends. Pretty much do an inspection of your car. Some places may be... near ECU, where your headunit is, near battery, anywhere where someone can play with and stuff up.

If those fuses that are incorrect, I would change them IMMEDIATELY. They will blow the component that its linked too.

Thanks mate.

> If this happened right after the alarm install, the installer could have mistaken the lamp wire as a ground. It is easily done, i accidentally did this to my mates car, while installing a stereo head unit. When the lamps are off the wire measures as ground, but when you turn the lamps on the fuse blows as wire becomes live.

> If you recently installed a head unit - read above

> Always replace the fuse with it's correctly marked rating. Fuses are there to protect the wirng, the last thing you want to do is to rewire you car.

Hope that helps

PS: If you are uncapable of disconnecting your all power wires to your alarm (inc ground), then go back to your installer, as them to disconnect it, replace the fuse and test the lights.

i had this problem in my 32,

found an un termintated wire behind my headunit with exposed wires, was earthing and blowing my fuses.

check back there for exposed wires plus what the other guys said

good luck

Thanks guys.

Someone also broke into the car recently and pulled out the ashtray to, i assume, get to the head unit. Maybe theyve pulled on the wires there and thats caused something.

Actually, on a reasonably hot day recently, my alarm went off twice for no reason - never done this before. This was around the same few days that the problem happened.

Bring on the pain - time to fire up that freakin' multi-meter and get my electrical tape out

I had the same problem but with my R33 Gts-t.

The rear light was in the "unlock" position and kept moving in and somehow caused the circuit to short and blow the fuse.

Maybe have a look at the taillights make sure its all fine?

This story ends happily..... managed to find the problem last night, one of the 40 thousand wires in behind my head unit / aircon / guages was obviously shorting somewhere, pulled that apart and tightened up all plugs and re-arranged the wires and bingo - no more popped fuse.

Whent the $%&$ broke in they must have had a play around.... never trust reservoir, melbourne.
