Lose reception when dash cam plugged in

Hi Folks,

I have a dash cam that plugs into the ciggy lighter. As soon as it plugs in, I lose any radio reception i had. (Could also just be static over the top of the radio I guess).

I'm about to wire a second 12v socket into my glove box so I can have the camera plugged in a little more discreetly.

What should I do to ensure I don't have the same problem when the new socket goes in? Can I add a noise filter thingo? Should I insulate the crap out of everything?

Thanks in advance.

Is it a plug into the lighter style job. If it is, replace the power supply with a half decent one and all should be well. Same thing happened to me, I replaced the supply with a belkin one I had and no more interference.

Did you buy your Dashcam on Ebay?

Most of Ebay products don't comply to our RCM/CTICK standard hence why such interference. Also if you're to wire it to your cigi socket, don't forget these things are around 5v and not 12v. 

I did buy it on eBay. I'll check the plug whether it says 5v or 12v. I was going to retain the cigarette lighter plug, just have one in the glovebox. This should then still step down to 5v wouldn't it?

That's an easy enough job, I can get a Narva one from Autobarn for under $10 I think. 

 

Thanks guys!

Then that should be fine.

If it still play up after you have moved the cigi location, try wrap some foil around the circuit board, that should help a bit. 

Disclaimer: Do this at your own risk :), try to avoid short circuit the thing.

This is the place to start (in my opinion).
If this doesn't work then look into shielding the wiring of the dashcam (back to earth). Any spurious noise coming from the dashcam or associated parts may be ruining you reception.

Thanks guys, much appreciated.

Its worth noting that the static is not the engine revs type of signal noise. This is a non-alternating constant static which is why it seems to be the reception to me.

I don't listen to the radio a lot, but broken things just get under my skin.

I'll be trying to get the plug in the glovebox this weekend, i'll report back afterwards.

      Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!

      The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...

      Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.

      I don't believe I posted pictures of the second oil pump pickup I added so here they are. Data shows it gets oil pressure up to the relief pressure much earlier in the RPM. Is that important? Not likely... This was just another attempt to fix the bearing issues.   I also heavily opened up the inlet to the pump since it now had to flow oil from two pickups. I believe the diameter increased about 1/8".
