Moss offers three fuses for the TR3. It was my understanding that both main fuses were 35 amp and the one under the dash was 25 amp. What is the 50 amp for? Also...If the orignal 35 amp equals a modern 20AWG.....what's the recommended modern one for the original 25 amp fuse?

Earlier cars used a 50 amp fuse for the horns.
Normally, an AGC 15 would be the nearest equivalent for a Lucas 25. However, the original 25 amp fuse (for the in-line holder under the dash) was rather larger than required to protect the circuit, IMO. You could use an AGC 10 if you want. (I think I've actually got an MDL 8 in there, mostly because I inherited a big box of them.)
