Was just wondering if anyone had changed the fuse holder from the alternator to bat. The fuse seems more than fragile. Would it be feasible to update it with a more sturdy blade fuse holder and fuse? I'm not sure what parts would be available etc.

I've never had to replace mine yet and the car's 8 years old. Don't think a blade type fuse can handle 100A.

I guess that's answered my question, I just got the impression from other posts I've seen that the fuse is a bit delicate, perhaps not then.

They can go. If you're worried about it, just keep a spare in the car!

Don't know, never seen one. I'm sure they can't be too expensive from the local TVR dealer though.

Think mine cost about 10p.

It looks like two electrical "Y" connectors (crimp jobbies) joined together by a flat metal strip (fuse)

Y_____Y this sort of configuration.

Hope that makes sense.

I guess you could replace it with a maxi blade fuse as they can handle up to 100A.

I've got a couple on order from a main dealer that haven't turned up yet. Looking at that pic it looks totally different to the one that fell out of my fuse holder in bits.

I spose the point of the thread was to see if there was anything that wouldn't corrode so fast and was quicker to replace and get hold of in a general motor factors. My car currently has an adapted blade fuse fitted by the bloke from the AA.

Just checked out that link Wildeep, thanks. Looks as though there's a couple of alternatives including a straight swap for a Midi fuse.

It sits on the underside of main Chassis Tunnel just behind the driverside wheel, and not to far from the Starter Motor. Thast on my 96 500, Think its also near the battery on some( 4.* maybe?? )

Some 4.* don't have one at all. Mine doesn't - at least I've never found it. It's absence was apparently confirmed the other day when I ignored good practice and changed the V belt using a metal spanner and didn't bother to disconnect the battery first . After the fireworks, the battery still apears to be connected to the alternator. QED.

Mine is near the battery; that's on a 2000 Griffith.

I have had to replace it: it melted, destroying the plastic holder and also severely damaging the steel nut and bolt, if you can imagine.

I had to make an emergency spare from several lengths of lower capacity fuse wire twisted together, until I could get a new plastic holder (and fuses) from Offord.

I don't want to confuse things but on my '97 car there's 2 of these strip fuses, one near the battery that I believe goes to the starter???? and one that comes off the alternator to the battery - attached to the underside of the chassis near the starter motor.

The one near the battery on mine goes to the fusebox, not to the starter. If that blows you wont get any power to any circuits at all. The starter is wired direct to the battery.

Calum, you probably have another 100A fuse tied to the chassis near the starter.

Hi Chaps....

My 80A one went the other day and i had no electrics at all luckily i was in a 30 doing 30 so it wasnt too bad, the RAC guy made up a blade fuse and wire to fit. Spoke to the TVR dealer and he told me that they do just go (current passing through stressing the alloy fuse) he told me that he changed the 100A one at every service. I think the 80A one near the battery is something to do with the aircon. My advice is to get it replaced at your next service, just bought a couple for £1 each, if anyone has any probs getting one drop me a line and i will give you a contact number.

Cheers,
Lig.

Thansk Wildeep,
£3.75 for P&P so will have to order some more stuff to make it more viable.
Maybe I should get a load for the Grwol and sell them for 50p each.
