Where is the infamous 100Amp located

As per Mr Wazzock it's tucked under the airbox so the whole thing needs to be removed. Personally I'd leave it, they don't fail that often and why uprate to a 125 - if the 100 blows it's for a reason.
Oi zippy, you don't know me, you've never met me, I don't know you, so don't call me Mr Wazzock 
OK !!!!!!!!!!!!!!!TVRWazzock said:

It is true that they do not fail often but it is one of TVRs known problems and if it fails out on the road it is a right pain (battery goes dead and the car stops).
The problem with the original flat plate fuse is that it mechanically fatigues and often cracks in the middle. If it does crack it can cause a hotspot which has been known to melt the carrier.
The fuse is easy to change:- remove the airbox (don't forget the fiddly hidden catch underneath - slide your arm under the airbox from the front and the clip comes to hand).
The fuse carrier is just above the alternator. Either disconnect the battery or insulate your socket spanner to avoid shorting to earth.
Undo the two nylock nuts (the fuse usually has open ended mounting slots so you can slide it out - however your new fuse may have holes so you will have to completely remove the nuts). Fit the new fuse - do not overtighten the nuts - the screws are only interference fit into the plastic carrier and if you get too heavy handed you will damage the carrier. Close the carrier, re-fit the airbox. Job done. I did it in 20minutes and I am fairly useless!

As Mr Monty Quick says the original 100Amp can crack in normal use, first you will usually know is that you will get a low voltage warning come. Depending on electrical load you can have between 10 and 30 minutes of driving before the voltage gets too low for the ecu to operate and then you are forced into changing it at the side of the road.
It is a worthwhile use of 30 minutes to change it for the ceramic version (they don't crack) in the comfort of your garage.
