Team 130 had our first 35A fuse go all brown and sulky on the way up from Lands End. About 50 miles later, its replacement followed suit. Both were new, so I'm thinking maybe a duff batch. Wipers, indicators, fuel and temperature gauge were all thoroughly disinterested in life without it.
Oh, and for some reason the TR6's fuel cut off inertia switch triggered at a fuel stop on our way home after the event. Of course, it waited until we'd told everyone about the run and how good the car had been to us. 🙂
