Sometimes electrics are annoying!!

[Alex86]

My rear worklight decided to stop working, so I decide to go fault find.

First things first, pull the fuse- I didn't expect it to be buggered as I have an illuminating switch for the light, and it lit up, so power was going through. Fuse looks fine, put it back in.


So next I go and remove the light, pull the heat shrink off the connectors and separate the join. Test the light directly on the battery and all good. Multimeter on the supply and getting over 12v.

Scratching my head....

Anyway I accidentally shorted the connection. No more volts to supply the light, and the illuminating switch light is out. Ok I'll go swap the fuse as it probably blew. Pull the fuse and yep this time it's got a clean break. Put a new one in and all of a sudden the work light is operating correctly!

Go figure

Stupid electrics!!!


Note for next time, just swap out the fuse or get the multimeter on it.

Yep sometimes i find its the simplest things with electrics......I've learnt from my own mistakes over the years!

I'll jump in and agree - have had a fairly annoying problem with my hardwired dash cam for the past couple of weeks - when I start the car in the morning the dash cam won't come on, but in the afternoon it's fine! Have swapped it for the cam in my other car which worked fine but this has the same issues, and tried a different cable and both cameras work regardless of the time.

Went out 10mins early today so I could do some troubleshooting while it's actually happening - and find out almost immediately it's just a loose crimp connector behind the dash! Why it's such a repeatable fault where it only works in the afternoon but not in the morning has me stumped....but either way, time to break out the soldering iron and make sure it's a solid connection this time.

Yeap, a sixty amp curcuit breaker will not stop a 125amp fuse from blowing.

If you want fun try trouble shooting what a HF radio can do. For me if used before the phone connects then it will not do it automatically but connect fine manually, and if connected before transmission then no problem. You can spend weeks trying to get an auto tune antenna to work and other times it just does. Mine does not work well with Kaymar bar open but works perfectly with it closed. Learning about RF earth being different to normal earth.

Lose or dirty connections can be a right Royal pain. Also, I found out ASC light came on and cruise control did not work. Reason? Blown breaklight fuse!

Now if soneone can tell me how to shut up permanently rear reversing sensor racket they will be right for beer that night!

Ent......pair of wire snips might work

EDIT......just realised the buzzer is integral within the reverse control unit from memory, so might be a bit more difficult.

Find out which pin in the trailer socket turns it off and either hardwire a switch in or plug in a dummy plug to the trailer socket (with the appropriate pins shorted). I assume this would work as I understand reverse sensors get disabled with a trailer plugged in, otherwise they would go off constantly when reversing a trailer.

Check the trailer socket first. See if the buzzer stops by lifting the socket cover.
Has the socket ever been replaced? Aftermarket sockets can have either NC (normally closed) or NO (normally open) reversing sensors contacts as various makes of vehicles can use either. Some auto electricians don't even realise this.

My understanding is the Challenger is not wired with a sensing wire so you when towing have to manually switch it off every time you start the car.
