Tail Light Fuse Keeps Blowing

[akqrate]

Yesterday, got a mate to install my new pioneer head unit.

Somehow he blew the dash fuse, so we replaced that, but in the process of trying to figure that out, we somehow lost constant 12V coming to the clock/deck.

To get the deck/clock working, hee then borrowed the constant 12V from the double blinkers, and then replaced the fuse and the tail lights were working again. Today, I turn the car on, stereo plays, dash and tails are again shot! What's happened? Any ideas? I'm freaking out here, and I've scratched my dash real bad. Has anyone else also found that to refit the console behind the steering wheel is a real pain in the neck?

To save myself $50 for a deck install, I've now somehow got an electrical problem that might take more than $50 to fix, and a badly scratched console that I can't stand looking at.

Skylines are easy for HU installs.

Sounds like when he has taken the hazard lights constant he has managed to split the insulation by pulling it through and its causing a short whenever it hits metal, or he forgot to solder and tape the join. must solder it or it can pierce through the tape and still cause a short. thus blowing the rear tail lights fuse.

Best spot to pull constant from is the ignition barrel (its where i go to straight away if there is no constant or accessories power in the plug where you put your deck)

sounds like you need to go to an installer and pay for a system check and rewire. dont pay anymore then $40.

Where are you located? i might be able to direct you to an installer who works for the same company as me.

sounds like you shouldn't let friends that have no clue what they're doing rip your shit apart...

but yeah, skylines are an easy install, so far only beaten by my previous car, 78 honda prelude... mostly cause there was no spot for a head unit, so i got a holder and bolted it on, tucked wires up...

If this guy cant do this right, i suggest taking his tools off him...

good luck with fixing it

Dude, lol, the car before this was a Prelude as well. And the same mate that installed it said that it was the hardest car he'd worked on to date. The guy has his own audio business so I figured I'd give him a go first.

I'm at Sydney, Castle Hill to be exact.

thats pretty sus man... the hardest cars to wire up are normally corollas, cause they like to change the colour of the wires and be unique... last corolla i put a HU in, the 12V+ was pink, ground was yellow and the ACC wire was grey...

the REALLY stupid thing is, for the rear speakers they used red (12V ACC) Black (ground) brown (also ground in a lot of cars) and yellow with a red stripe (12V+)... confused the hell outta me... i was shocked...

either way... your mate sounds like he needs to go back to audio school you are earthing a wire somewhere...

This is why we dont let primary school kids work on cars.

You need to

1- fix the constant feed to the deck, take it off the hazards and use the factory loom

2 - replace the fuse for the factory radio constant

3 - disconect the radio earth from the vehicles illumination wire

4 - replace fuse for taillights

5 - re-earth unit to chasis

6 - go and get big stick

7 - belt "your mate" over the head with it many times

8 - feel better

9 - get him to pay for the reapirs to your console

easy....

HAHAHA, dude you're the man! I like lucky number 7, always works for me.

Apparently he used the ground from the factory radio ISO plug, so that's ok right? The illumination wire is still just taped up that's all. Where's the fuse for the factory radio's constant?

Better to ground to the chassis than use the ground in the harness plug.

i think i've seen a tutorial on fitting a head unit in an r33... that'll probably be your best bet in trouble shooting this issue dude but GL anyways looks like heaps of helpful info in this thread from people.

[DRD-00F]

the fuse for the factory radio is i believe near your right knee when your sitting in the drivers seat... there a fuse for the cluster in the engine bay, so it might be in there... ive never actually had to replace a fuse strangely enough :s

but yeah, grab your own ground somewhere, its easy as... and find that positive thats grounding...

[akqrate]

I've never come across a site as helpful as this... thanks guys! I'll go in for round 2 sometime either tonight or the weekend.

good luck mate!
