A bit more done today.

I put a multimeter on the battery and it was reading 10.8 volts so the battery is toast. I'll get a new one ordered.

I'd previously checked the lights and the only thing that wasn't working was the hazards. I thought it might've been the switch so I squirted some contact cleaner in. That didn't work so I swapped out the flasher unit for a spare that I had (Dolomites have separate flasher units for the indicators and hazard warning lights) and they started working again.

I gave the interior a clean and it is looking a bit better. More like a car!

I'm going to change the brake fluid so that's another job to add to the list.
