Robin, the fog light switch isn’t a latching switch, it’s a momentary switch. The only one of four that isn’t latching. And don’t forget it will only latch/function when the main lights are on.
Regarding the fuses, the factory did notice that the PCB was functioning as a fuse when there was an indicator fault and started adding extra fuses on some later cars. They’re not that difficult to add. They are located behind the dash.
Rog, where would be the best place to wire the extra fuse, would it be for each indicator side before it enters the PCB?
Many thanks
Will
Some later cars had a little supplementary plug-in loom behind the dash with a couple of fuses incorporated. I have a dim recollection that the loom could be purchased from Morgan as an add on. I may be completely wrong but might be worth giving Mr Rutter a call?
Failing that it wouldn’t be that difficult to add a couple of 5A fuses on the N/S and O/S indicator supply wires exiting the PCB.
Wires GR90 and GW86 on pins 5 and 9 of the 12 way Dashboard PCB connector

And as always, the caveat.... Go careful modifying your car. Check everything for yourself. Don’t take my word for anything, I have no electrical credentials.
PS – there’s a nice little video by Dave showing the loom on this
