I seem to end up doing a lot of wiring and whatnot, so I'm collecting all the bits and bobs here.

• Megasquirt EFI gets its own section as I'm a serial megasquirter
• Defender blade fusebox upgrade
• Defender twin electric fan conversion - Using 100% Land Rover parts.
  • Old dual-speed twin-fan circuit designed by Ian / BullbarCowboy from LR4x4
  • Intermotor fan switch part numbers, threads, temperatures, wiring
• Solar panels fact Vs marketing
• Alternator lamp diode - Why putting a diode in your alternator warning lamp feed is not necessarily a top idea.
• Battery voltage is not a good indicator of battery health
• Crimp Or Solder? - AKA how to start a holy war on the internet
• VDO temp gauge
• Lucas / BS / Land Rover standard wiring colours
• Stuff you should know about fuses
• Useful universal power supply / battery charger / solar controller / etc. etc.
• Power for your Overlander

As much for my own personal reference as anything…

• Farting about with a caravan fridge
• Automotive & leisure battery specs (mostly random numbers for personal reference)
