One pin too few!

Last month’s diagram in the relay article: ‘a simple four-pin relay circuit.’ Well, there’s a missing fuse on the switch circuit! Doug Woof Ralph says: “Doug is absolutely correct. While clearly an indefensible mistake, the reason I showed the fuse on the high current side of the circuit was because I was trying to show the extra bits added to a bike wiring and all the switched circuits would already come from the standard fuse box: to be fair though I should really have made that clear.”
