Hi Gareth.
All input is welcome. 👍 When I left it unlocked in the garage it was after having it running. I don't think it locks itself then, only when you unlock and not open a door after 30 seconds or a minute or whatever time it is.
Yes I have the handbook and a Haynes manual so can identify all blade fuse locations and what they do.
I did wonder about the alternator and did disconnect the small wiring connector and no change but I need to test with all wiring disconnected. Will be down the garage tomorrow to do more testing.
Thanks.
