Hey guys really need some advice, i just swapped my battery to find that the terminals were the wrong way round was only connected for maybe 5 or 10 seconds before i released. i quickly pulled the terminal off and now NOTHING works which i find strange, even the headlights wont turn on when the ignition is off? any ideas to what i might have broke?

 

thanks guys, feel really silly right now

You have probably blown the main battery fuse, in the small fuse box next to the brake master cylinder

 

Hi mate,

Gonna have to start checking all the fuses, ... with your fingers crossed...

 

Even all the main fuses.

To slow lol...

my mate did this on an old escort and had to rewire most of the battery live's as he burnt them out

 

hope its an easy fix

thanks so much guys, just has a look and sure enough its blown, quickly bodged it and it starts and moves (thank god) lol the radio seems to have a blow fuse but i think that's it. Really appreciate that guys thanks :D :D :D

ok all is still good except for my amp which i fitted this morning and was about to test, so got to take it out to try fix it, but at least all the important bits are still working

Radio fuse is in the drivers footwell mate. 10amp

check all the fuses one by one hopefully you have a shed load of fuses gone and no burnt wiring loom of whitch i had about twenty years ago on a dagnhnam dustbin.

after spending loads of time checking everything the only casualty is my amp which is now completely short but I'm not to worried, just happy the car is fine :) thanks guys

I'm good with electronics m8 - I may be able to fix your amp if you are stuck

I'm pretty sure its the voltage regs (or at least that's what they look like could be fets) iv not checked yet, although i might just buy an old 1000w kenwood from my father in law

What's the part number on the devices you think are regs?

ill have to take it apart a bit more before i can see that haha will have to have a look when i get some free time

It should have done the fuse to the amp...... Usually does the eath track on the amps circuit board around the power supply section..... you will probably find a piece of the track has blown, clean up either side if it is broken with fibreglass pen to get enamel off. Solder a piece of wire carefully across break and it maybe okay.... That is if the track popped.....?

A blown track or a fuse would suggest an open circuit amp not a short circuit one

 

Probably it is a Class D amp (which in reality is more related to a Switch Mode power supply circuit than a conventional amplifier) and the output device(s) - probably those things that look like regulators and are likely to be short

Oooopppss.... typical Rich.... I should have read the post more carefully.....

Brain in fault finding mode and missed the short circuit bit.....:stupid:
