Trying to finish TR7 restoration by Spring.
Now working on electrical. Allot of information is out there on later cars but allot of info lacking on EARLY CARS (1976 Coupe)
Cannot find DEFINITIVE information regarding FOUR fuses in fuse box.
From top to bottom what is amperage of each fuse? As usual this should be simple, but guess what, it ain’t.
I have allot of people guessing but nobody actually knows for sure. Just can’t seem to find a simple diagram that shows the amperage of each fuse.
Any help appreciated.

I found this for the '76 Canadian model. Its for the 4 way fuse box but also covers the two additional inline fuses

76 TR7 Owners Manual

The information is scattered around, but pg 41 gives the circuits and location of each of the six fuses, & page 77 details the fuses ratings (Warning - Lucas ratings are the current the fuse blows at, not the rated current, unlike most fuses)

According to this there are 3 x 50A, 2 x 35A & 1 x 15A fuses so look at the wire sizes & the thickest wires will be the 50A circuits, the thinnest wire the 15A

From the '81 models fuses I would surmise

1) 15A red green - feed to aux lights

2) 2 x 35A white - vent fans, wipers etc

3) 3 x 50A brown - air conditioning / cigar lighter / heated rear window.

Hope this assists
