Fuel pumps n brake lights
Jon Ison - 27/3/03 at 07:00 AM

spent a while scratchin head over a dodgy fuel pump, from time to time blew a fuse but could'nt find owt wrong, then in a moment of inspiration i realised the odd time it did blow i had just braked too,

you guessd it, running of same fuse, i had used trailer 7 core to rear of car, and one of the cores had gone down to earth, yeap the blue one i used for the brake lights, luckily i had not used the black wire so i switched over to that, but the cable as no aparent damage along its length and as only been in just over a year,

Moral, don't use the blue wire for your brake lights ???? and don't run the fuel pump of the same fuse, all boll**s of course, but just thought i'd share the warning on trailer 7 core wire. got there in the end,

That fuse blew because that was the first time you used the brakes since you've been on the road!!!

Bloody maniac

i think on my car the std fuse for the pump is 20 amps. that would be a bit big for a brake lamp which could be fused at 5 or 10 amps.

I used 18 fuses on my car and still run out of capacity!

I'm using 7 core trailer wire too, and have used all 7, what have I got extra????:

Tail lights
Brake lights
Fog Light
Fuel Pump
Fuel Sender
Left Ind
Right Ind

And BTW, did you pass MOT with the LED fog light? As they are eligidly not road legal.

Ideally, you should have seperate feeds for at least one of the rear lights, or the number plate. This stops a single failure putting your whole car in darkness.

I also had to mount an impact switch to stop the efi pump running. This goes to the efi box, and needs a further feed backwards.

I also have a reverse light.

Then there are the two abs cables.

Nothing like keeping things simple

its a bike pump, 15A fuse fitted.

found the prob today though, went for MOT and the prop had caught the cable when i had "bottom'd" her over a speed bump, dint think the axle could move that far, sorted with new bump stops, the car is 74 age related, don't need a fog light so not sure of the legality of it, but aint bus's running led rear lights these days,

BTW, shame bout the pier.

LED's for fogs have to be behind diffuser lens, cos you need to be able to see then from an angle, and undiffused LED's point in one direction.

It's a real bummer about the pier, lovely building. Lots of people recon it was started by the owners of the other pier who've been bloking the redevelopment.
