I have followed Dave's plan.
put in a new fuse.
Input 12v - no problem
Switch test with output connected to test bulb - no problem
Re-connected everything and - no problem, brake lights working.
Realised that the reversing light is on the same fuse so checked the bulb . looks alright.
Pt the car in reverse, no engine just ignition on, Blew the fuse.

I will have a look underneath tomorrow at the fitting but where do i find the reversing switch ??
hope its not in the gearbox.

Thanks for continued assistance

But must the reverse switch be the faulty item or could it be a short on the way to the rear drive bulb?

Paul, as it's far easier to access the light / bulb I'd start there, the bulb holders are a known source of trouble due to corrosion & even the bulb could have blown & shorted internally (worth a quick swop-out)

Happy birthday Jon!

Paul I have known several reverse light switches go short circuit (seem to be mostly on Minis - the originals). They are located above the gearbox usually activated by gearlever position. However, as Jon says, start with the easy bit smile
