HELP!!!!! Electric Problems
Discussion
I am the proud owner of a 97 5.0L TVR Chimaera and it is giving a bit of a problem.
CAN ANY ONE HELP!!!!!!
The battery went flat the other day which then caused my oil pressure gauge to drop to 0.
Stopped the engine called the RAC
Mr RAC said my battery was knackered and I needed a new one, so I changed the battery then I checked the alternator and whilst on tick over the meter read 7v so have now replaced the alternator and now this one reads 3-4v on tick over and about 5v when the engine is revved.
The belt seems fine as well no nasty screaching / sqeeking coming from it.
The battery light is staying on and not going off, with this new alternator, and I really am stumped, does anyone have any ideas or know what I should check next???????

Have you checked the big 100 amp fuse ? I had same problem
on the Tuscan and after buying a new alternator it turned out
to be a 99p fuse. If it is in the same place as the Tuscan then
there should be a small plastic cover just above the starter motor
and the fuse is inside. Check it carefully as mine looked o.k.
but on closer inspection was cracked right through.
Hope this helps.

Had exactly the same two weeks ago. RAC man said it was a new alternator job, so it was time to go home on the low-loader 
Phoned up Paul @ Austec (01293 - 531080) asking if I could drop it in (low-loader again), and he suggested I get under the car and check the 100amp fuse. To check - jack up the front of the car and place on axle stands. Then slide yourself under from the front and look for a big red cable on the right hand side. This will go into a small black plastic box bolted to the bottom of the engine. Flip the top off and see what's there. Chances are you'll see a cracked grey metal fuse. Use a small socket to undo both bolts, and remove the offending part. You are then faced with a choice - either replace the fuse (easy if you have one handy), or just connect both cables to a single terminal (more of a pain because there isn't much space). I won't make so bold as to suggest which is preferable...
Good luck,
Mike.

Hi
Thanks for your help here, I have just found the red cable and prized the cover off no fuse just a flattened piece of wire split in the middle, now what exactly does this fuse look like, sorry to sound a bit thick but does it look like a 13amp type fuse or does it just look like a bit of wire.
It looks like this:

I will!
IMO the 100A fuse is a total waste of space and introduces a notorious weak spot into an electrical system which was non too clever to start with.GreenV8S said:

Wouldn't want to add any extra air resistance now would we
