Hi I bought an mg tf about a month ago , my rear lights start flickering when I'm driving every so often and having owned the car about 4 weeks last week the alternator burned out , I have replaced it now but my light are still playing up , I'm worried that the new alternator will burn out due to an electrical fault , can anyone shed some light on this for me please.

If all the rear lights are affected I would be taking a close look at the boot lid loom, as this is a known area where wires are prone to damage and could give you the problems you describe.

Would agree with that, had problems with this loom too. This also affected the boot alarm setting. Easy enough to do and you will probably be able see signs of damage as soon as you look.

The loom is on the left hand side as you look in the boot area, near or attached to the left hand hinge, even if it looks ok peel the tape and copex back and you will almost definately find some damaged wiring, nice easy fix :)

Sorry for hijack but could this loom be responsible for an intermittent issue with my car? Occasionally the N/S rear indicator wont work and other weird electrical things happen, i.e. the fog light warning light comes on when I brake. It goes away when I waggle the wires going into the rear light cluster.

I've check the wires/contacts on the rear light cluster and everything seems to be OK.

TIA.

In word yes just carefully cut away the tubing and examine the wires they will break at the point where they flex the most. To repair just solder and shrink wrap. It's worth doing properly.

Three wires in my loom were also broken when I investigated after a following friend had noticed the flickering.
I crimp rejoined the broken wires and extended a couple more, which gave the loom more room to move when the boot is opened and closed.
