Where does the live feed from the battery go to?

[Jakey]

Ill try the battery next. My mates got a Combo so ill use that.

No mate, completely the opposite. It's got a dash, 2 front seats and a bit of front carpet!

[MattBrown]

you might as well try another known battery, and just jump it if it does discharge it.

and you havent got a massive sound system wired into the perm live or something .

Its not happening that a 380ah battery is flat in 90 seonds

That cable will melt way before 250amps

[Jakey]

What do you mean Matt?

if you stick a proper discharge tester across a battery, it gets hot as hell in about 5 seconds... after 90 seconds of rapid discharge, you'd have a fire & an exploding battery......

try this. with the battery disconnected & every switch turned off, things like the clock disabled & the door switches for the interior light taped shut, put a multi meter set on ohms across the battery terminals on the red & earth cables, then you'll see if there is a short circuit, then remove fuses & things like the alternator wires till you find the short.

i would also advise you get a discharge test done on the battery for peace of mind.

I would stop assuming its something to do with the red cable.

If you've pulled all the fuses and it still does it, pull the relays instead and see if the problem persists. If it doesn't, re connect them one by one until the problem returns.

This also included the fuel pump relay, which will be in the engine bay, not the fuse box, and there is also a relay in the boot on the nearside, behind the arch liner trim.

i have 2p on the alt over charging and cooking the battery.

also disconnect the earth, connect the meter in the amps aetting and see what amperage is being used. anything over 0.15 amps is high.

Please be carefull playing with this.

The ohm setting is to measure resistance accross a dead circuit, so make sure you take the battery off, then measure the resistance.

It should be very high, like 100+kohms.

does the battery charge light go out when running ?

[Jakey]

It's got a digi dash in. The charge is always on the 14v bar, sometimes creeps up one when you boot it.
