Thank you, Peter.
You guidance is always appreciated.
My MKV has the three spool type and is fine. Perhaps the MKIV will benefit from the solid state regulator?
With my thanks as always,
Tim
Ā£320.00 + post! I nearly fainted. 
Thatās $600.00 AUD!
Iāll keep looking for a good original one.
I received my fuse holder from Holden today, ordered Oct 27 so 13 days in transit from UK to USA. Well wrapped in corrugated cardboard and plastic bubble wrap.
The mounting hole spacing is 1-13/16" so the holes in my scuttle that I previously thought were right are not.
However, looking again I find I have another hole which I didnāt pay attention to before because it looked too big, that now I see has been torn out, and the spacing is right, so it probably was originally for mounting this fuse box.
Right now there is no wire at all going to the lighter socket.
Anybody know what gauge wire and amperage fuse I should use? Not that Iāll be using the lighter, but maybe something like a tablet charger.
Hi Rob,
Mine has yet to arrive. Are you happy with the quality?
Tim
Hi Rob, if you are talking about the original lighter socket, it was manufactured before the current standard became the industry standard (probably in theā50s) and todayās standard accessory plugs are not compatible for size or for making contact.
Cordell Newby at Western Jaguar in the U.S. had a brilliant copy with the same style of lens, but made as a standard lighter/socket. He was out of stock a while ago and I donāt know if he proceeded with replenishment.
I found this fellow on eBay. Just put this Item Number into the search bar. Heās in the USA. It might be the āstandardā size? It canāt hurt to ask. eBay item number:
390229546109

It looks definitely like the standard type because of the heat shield, and confirmed by their description. If I were missing one, I would have one of these.
Iām happy with the quality from Holden, in fact it says Made in England on it and if itās not new I would have thought it was NOS.
I have a couple of those 35 amp fuses courtesy of Roger. 
A lot of the wiring is 14 gauge so if nobody has a better feeling Iāll go with that.
I got one of those lighters from Cordell a year ago.

The reproductions do ālook the partā but they are a smaller diameter so you canāt put the modern lighter in the original holder.

I bought one for my MKV, though have yet to fit it. I wonder if it would charge an iPhone, being positive earth and drawing charge from a generator? Iām sure I couldnāt have any lights on while I did this! 
I swapped my car over to negative earth for various reasons and I put a small fuse in my cigar lighter supply and can plug my sat nav in there now.
Peter
I remember the conversation we had about that some time ago. Iām really not that concerned about charging anything (I was being cheeky) as I take a few charging batteries with me to last all day.

So I thought I would put the fuse box on, discovered the 2BA cheese head screws I picked out donāt fit, head to big for the recessed holes in the fuse box.
Does anyone know what size and head the screws should be?
The head canāt be larger than .260"
#6-32 round heads fit, but they seem awful small.
BTW this may be a date stamp on the box, 45 79, so maybe it is NOS after all?
And I discovered there is a plywood footboard in the way, Iāll have to remove it to get the nuts on the screws.
Turn the heads down on a lathe? Or failing that, on a drill with a file?
Peter
Pity - tried to order one- been waiting few months but nothing so far
Did you order one from him on eBay and it hasnāt turned up?
Tim
Yes - the lighter - still trying to fill the holes in the dashboard!
