Hi,
Not knowing any info about the car, my buddy has a car that is losing
power, and causing a flat battery.

It turned out to be the car alarm, the ignition wouldnt turn the car over
because it went through the battery.

It was a cobra alarm.

I hope this helps.

Today I measured the current drawn from a fully charged battery fitted
in the car and was surprised to see 7.5A drawn with the ignition and
lights
off. My plan is to take out each fuse in turn to trace what is taking the
current
but today it fell dark before I could get far. Tomorrow I can restart the
trial and error way of finding the fault. But if
anyone has any suggestions I would be very grateful. I am assuming that
the
battery went flat because of a fault external to the battery, but maybe I
am
misunderstanding the system, the 7.5A is a red herring and the battery is
faulty.

Thanks in advance

A 7.5A drain without anything on is clearly too much. I'd return to your
testing tomorrow and try to narrow it down. Post what you find here.
