Changed the alternator in daughter-in-law's Rover Streetwise today. It failed last Thursday - charging light came on going to work, and she broke down on the way home. Son went out to rescue her, she returned home in his Omega containing my grandson Tom, then son rang me to rescue him. A spare battery got him to my place and he went home in my spare Omega. Tom, aged 3, announced that Grandpa would mend it; so I did.
