battery drain

[hoogwoud]

hallo i notice one off the front brake pad wire is broken or ripped off is it possible that it drain my battery from that wire if put multimeter on it goes see some movement losing in 3 hours around 6 amp but if i try parasitic test it says nul bit out off my depth i think thanks .Is there a way disconnect fuse or anything else thx

No, I doubt it.
If its the live wire and touched earth it would pop a fuse.
Or if its a single wire system and touched earth it would light the brake pad warning light.
I certainly wouldn't drain at 2amp/hour

Brake pad sensors rely on a connection to earth to put the light on & only work when the ignition is on.

If you are losing 6 amp-hours in 3 hours, that is 2 amps, which is way higher than usual, so you definitely have a problem. I'm not sure what this 'parasitic test' is. Is it a function on the multimeter?

One way to test for battery drain is to take out one of the fuses, then set the meter to the 2 Amp range, and connect the meter across the two connections where you have just removed the fuse. If everything is switched off, amps measurement should be a few milliamps, certainly no more than 50 mA. 50mA is 0.05A.

Test each fuse socket in turn, and one of them should be the one that's draining the battery. If none of them shows a problem, maybe one of the diodes in the alternator has failed.

If no result there, other faults are possible, so maybe a good autoelectrician will be able to trace where the fault is.
