Blowing Reverse Lamp Fuse
I had the reverse lamp burned out, so I thought. Fitted a new fuse, worked fine. Have since swapped for an LED bulb which was great and worked well for a few weeks. Blew Fuse again.

All the common issues of the reverse switch that I am reading about doesnt seem to be the cause. 2014 puma. Can I replace with higher amp to see if that helps?

As the LED bulb should draw minimal current, I would not replace with a bigger fuse.
The fuse is there for a reason Very Happy
My guess is there must be a problem with the wiring going to earth somewhere.
A case of tracing it back and eliminating each section Sad

^^^^ Agree, certainly don't increase the fuse rating it's there for s reason to protect the circuit and wiring.
There will either be a switch failure, short in the live or a poor earth.

My guess would be the switch, but do some testing with a Multimeter to determine there is suitable voltage at the plug and low resistance on the Earth line again at the plug.
Is the plug and socket got wet in it at all? Diesel$ Live$ Matter. ⛽️🛢️👨‍🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧
