I recently encountered the speedo and miles incrementing when trying to troubleshoot a no start condition on my '85 XJ6. On a cold day I started my Jag and it was running normal and I wanted to check my heater and heated rear window switch I installed last spring. The blower motors fired up (little noisy at first) and the rear window heat switch was on, then the engine started dieing and would not restart. I turned heater and rear window defroster switch off and attempted restart to no avail - acts like no fuel (waiting for warmer day to follow Dougs Fuel Pump Circuit Checklist), but I noticed the speedo was bouncing and the miles were incrementing, thought it was due to an electrical relay issue somewhere in the car that was causing some backfeed in wiring system. I disconnected the battery (thought it might reset relays) and left it disconnected for 2 hours and when I reconnected it the speedo bouncing and mileage incrementing stopped but the car still didn't start. Just thought I would share.
