Guys, recently Ive noticed that my radio is turning off for some seconds and restarting when I play around with any of the lights, like head or fogs. Not every time but especially often when I hit the high beam for a couple of times like when you wanna greet somebody.

Do you got a clue what could be the cause of such things?

 

Thanks and regards from germany

You likely have a bad earth somewhere. Or possibly the headlight switch or dip switch have dirty contacts.

I had this happen when an exhaust pyro gauge was dying. It pulled the power in the console area low enough to drop the stereo out (and then as it died completely I couldn't start the car). I wouldn't suggest you have the same problem I did, just demonstrating that power issues have been seen to cause the same thing you're seeing.

The headlights pull a lot of current. If that current can't get to earth (on the other side of the headlights) you might cause some weird voltage issue in the dash/console.

Hey mate

Ye even though Im not very skilled in electrical stuff, thats the first thought I had. I have to edit my post, its not only the car thats going down its the ignition. I can tell by the antenna thats going down as you know well too, and by the defi gauges that start the launching animation.

 

So how could I attack this problem now?

I'd start by checking if the common grounds between your lights and radio are clean and tight. See my link below and report back if you don't find anything. Cheers.

      The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter

      Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)

      To back this up, I'm always looking on the outside, seeing the level, and then opening it up anyway, as I'm worried the level I've looked at, is more so a scunge line. Then you end up dipping your damn finger in it too depending on the type of tank you're looking at just to make sure I'm not going insane.   PS, Mark, polish up the none moroso one a bit and then give it a clear coat. The Moroso one looks to be way shiner (not mirror polished, just shinier) and it'll still look weird with the two different alloys beside each other. Either that, or Id probably paint them a flat black...
