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 :P

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 :P

> 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 :D

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.

    • Put a camera facing your dashboard so you can film the gauges. Head out to a straight but of road, and filming it as you go from a stand still at wide open throttle to as fast as you can/feel comfortable doing. Then film the dash board as you for example accelerate like normal onto a freeway. This will give us an indicator from Speedo of your expectation of slow, and will give us the rpm reading too to see if it's shifting. (Auto still has tacho from memory)
    • Buy yourself the cooling system pressure tester. Being able to pump it up, and have a gauge on it, AND have a cold engine makes it much easier / practical to diagnose. Additionally as the engine isn't running, you can listen for pin hole leaks as well as watching if pressure drops away. In addition, you can pressurise and while doing so, watch all the little rubber hoses. Some fail very brittle, and will just leak, while others can end up very soft and bulge. While a bulging hose isn't necessarily leaking, one of those small ones starting to stretch / expand in a bad way is an indicator that you'll be looking to replace that one soon   Depending on if this is a project car, or you'll be dailying it in the summer months would alter how I'd be most comfortable with driving the car and how I'd replace. If you're planning to use it as a daily, with no backup, I'd pull the engine, and replace all the external oil/water lines in one big swoop. At the same time do the timing belt, water pump, tensioners etc. Do not open the engine at all. We just want to replace all the things that are inexpensive as a single item, but a PITA when they go. By doing the above, you've made the car from a bunch of age related issues more reliable. If it's a project, and you like swearing while trying to reach into dirty hard to reach places to replace a single hose that may or may not be the leaky one. Just replace the leaking/bad ones as they need it. If it's a project and you'd rather swear at the car once and enjoy it as much as possible, then refer to the process I mentioned in how I'd want to do it if it were a daily. However, the approaches above do come down to how much spare pocket change you have. Pulling the engine and dropping over a thousand dollars on parts, may not be practical for you. Oh, if engine outing, I'd replace as many silicon/rubber inlet joiners as possible too.
    • Yeah, they're pretty dumb though...ie; they'll throw a solenoid error if the solenoid is dead, shorted, wiring is open circuit, or even if the driver transistor has failed (they can't self-diagnose much, they can only test inputs/outputs)... but if you wanted to try, I believe it's this protocol....(uses a long pulse indicator with short pulse counter)...    
    • Yeah I'll do what I can without taking off any major parts for now. If it becomes clear I won't get far with the engine in the car I'll have to think about the next steps. I am not too stuck on keeping everything 100% OEM, if there is better solutions, like converting most lines to braided with AN adapters, I'd rather do that than buy overpriced new "shit" parts.
