Headlights Shorting Out When Cd Player Is Hooked Up?

Hi Guys,

I have a problem with my stereo, i recently reinstalled my stereo. The issue I have is that when the stereo is connected and I switch the headlights on it pops the fuse that controls the headlights. It obviously seems to be short circuiting.

Another problem with the system: which consists of an amp and sub, is that when i change songs or adjust anything on the cd player the sub makes a big thumping sound. The connection of the grounding wire is very oversized and the connection is not the greatest - not sure if this is the main problem.

Have you guys got any ideas on what could be causing this problem?

Thanks in advance.

There is an illumination wire which i think is black with a yellow stripe. If you have wired this incorrectly, it would cause the problem you are describing.

Depending on your head unit, it may not need this wire, in which case you need to tape it up so it doesnt short. I know of someone who thought being a black wire, it was a ground, and wired it up to the head unit. There actually isnt any ground wire from the wiring loom, you need to ground your head unit by running a wire to the chassis.

Thanks for the reply trav33.

The cd player was working fine for quite a while before this problem. What happened is that the battery terminals were connected back to front. This cause part of my alarm to fry and the fuse on the back of the cd player blew. Before that episode system was working faultlessly. The things i have done is take out the sub and amp and put them back in.

I was also refering to the ground on the amp end.

Cheers :down:

That could be your problem there!

So if you disconnect your CD Player Head Unit, you can turn your head lights on and they don't short out?

Sorry bout the late reply.

Ive disconnected the cd player for now. My mate thinks it might have something to do with how the earth is wired up. He said to ground it instead of using the grounding wire, if that makes sense.

I havnt had an oppurtunity to do this yet. Though it was working fine how it wired up before the battery incident.

Cheers

There is no such thing as a ground wire (in the standard factory loom).

The black wire which some people think is a grounding wire, is the illumination wire. I'm 99% sure you are using this wire as your ground which is the problem! Do what ya mate said and it'll be fixed.

      Steps to DIY sanding car back ready for respray....

      By MBS206 · Posted

      To expand on this to help understanding... The bigger/longer the block is, the more it's going to work to sit on your far away high areas, and not touch the low stuff in the middle. When you throw the guide coat, and give it a quick go with a big block, guide coat will disappear in the high spots. If those high spots are in the correct position where the panel should be, stop sanding, and fill the low spots. However, using a small block, you "fall off" one of the high spots, and now your sanding the "side of the hill". Your little block would have been great for the stone chips, where you only use a very small amount of filler, so you're sanding and area let's say the size of a 5/10cent piece, with something that is 75*150. For the big panel, go bigger!   And now I'll go back to my "body work sucks, it takes too much patience, and I don't have it" PS, I thought your picture with coloured circles was an ultra sound... That's after my brain thought you were trying to make a dick and balls drawing...

      Oh I probably didn't speak enough about the small sanding block for blocking large areas.  In the video about 3 minutes in, he talks about creating valleys in the panel. This is the issue with using a small sanding block for a large area, it's way too easy to create the valleys he is talking about. With a large block its much easier to create a nice flat surface.  Hard to explain but in practice you'll notice the difference straight away using the large block.

      Yep I guessed as much. You'll find life much easier with a large block something like this -  https://wholesalepaint.com.au/products/dura-block-long-hook-loop-sanding-block-100-eva-rubber-af4437 This is a good demo video of something like this in use -    You have turned your small rock chip holes into large low spots. You'll need to fill and block these low spots.  It's always a little hard not seeing it in person, but yes I would go ahead and lay filler over the whole area. Have a good look at the video I linked, it's a very good example of all the things you're doing. They went to bare metal, they are using guide coat, they are doing a skim coat with the filler and blocking it back. If what you're doing doesn't look like what they are doing, that's a big hint for you

      HR34 GT speedo issue

      By isf · Posted

      The odometer does go up when driving.  Does this tell it is an issue with the speedometer itself?    Where can I look for replacement cluster? Or speedo? I can likely do the repair.. Will ER34 cluster work on HR34? Or do I need a HR34 20GT S2 specifically lol

      Mine's a bit bigger at 70x150mm roughly. The spots are flat, just can feel the edges if I dig my nail into it. I did fix some other other ones by both using my finger to sand that small spot (I'm a bit wary of doing this and creating hot spots and a bigger mess) and I also did sand over it flat and others, but this also worried me a bit because if I create an overall low spot on the panel on paint that is good.  Correct me if I'm wrong but as long as it's flat even if I can feel the edges, I can put filler because it will all be level once I sand it? I can see myself going in a circle after sanding guidecoat with 320 grit if for example the panel is flat with my hand but because I sanded the guidecoat I could have created a low spot again somewhere. Unless where I'm going wrong is what I mentioned previously where I didn't go low enough on the grits. It's 1 step forward and 2 step backwards here haha. I'll probably need to experiment with it more. Last time I go back to bare metal lol.
