hi I had a car imported and as I needed a rear fog light I got someone I know to wire one in now every time I press the button it blows the 10amp fuse so my number plate lights and rear fogs do not work , iv test fitted a 15amp fuse and it all works fine would it be ok to use the 15amp or is there a problem with the wiring any help would be appreciated

what wattage are the number plate lamps and the fog lamp? I think you are just pulling to much current for a 10amp.

seanvx

not sure iv got some led number plate bulbs I thought the same as it was running a 10amp for just the number plate bulbs and now the fogs have been added

if there was a fault the 15 amp would have blown to, it sounds like your pulling just over 10 amps, only concern is the wiring being ok of the increased loads but it should be ok.

seanvx

so you reckon the 15 will be ok whats the worst that could happen

mjp02wrx

worst that can happen is you numberplate wiring over heats and catches fire but i dout that , you will be ok running a 15 amp

seanvx

ok thanks mate , don't spose you know anything about wiring up a reverse camera I have to wire it to the reverse light

mjp02wrx

run a ignition switched fused 12v supply to the power source for the unit, use a 12v relay so you are not pulling the power off the reverse circuit, have the reverse light wiring on the relay so then u go in reverse the relay operates and uses the 12v supply to run the camera.

not the best at explaining sorry

seanvx

ok thanks so I wired it to the reverse light one end then wire the other end with 12v fused

mjp02wrx

Pin 30 connect to the switched fused 12v supply u need to run
pin 87 connet to the camera system 12v input
pin 85 connect to the cars reversing light wiring 12v side
pin 86 wire to an availabe earth

seanvx

ok thanks mate looks bit to complicated for me I might get pro to do it , I was hoping there would be like a how to guide on here

mjp02wrx

It is easy trust me, hardest part is getting the feed from the reversing light. But if you are not confident then yeah get a qualified person in to do it, should take them less than an hour

I fitted one on my old car but this is all new , I knew what wires were 12v etc

So ot trips out a 10a, so we advise putting a 15a in?

Find out what the problem is and resolve it. If you are running led number plate lamps the load will be alot less than with filament lamps in and it shouldnt trip the fuse.

If you still need a auto electrician i have used auto sparx in chatham a few times, very good but a little on the expensive side.

i would just use a totally separate supply straight from the battery that is fused near the battery use thicker wire that what you need and then if you want to add more things like a camera you can , it's the safest easiest option

most wiring in modern cars is designed just to do what it's built for and not designed for other things to be added , option above is not expensive either
