Hello,
I have a brava 1998 1.4 and I thought the alternator had gone but a friend looked at it and says there is a problem with the loom and it is draining the battery also possibly connected,is that the fuse which works the heater and lighter keeps blowing.
Can any one help and can I do this job myself?
Thank you in advance

the drain is from a short on the heater/lighter circuit. i believe the stereo is also on that circuit, and the interior lighting.

disconnect each thing in that circuit one at a time, then refit the fuse. the thing you have disconnected when the fuse doesnt blow, is the faulty part you need to replace. if disocnnecting everything in the circuit still makes the fuse blow then you have a wiring short on the circuit, which is easy to fix but often a nightmare to find.

fingers crossed its the usual case of someone fitting an aftermarket stereo badly and there is a short on the wires behind it.
