I just tried to fit a dash cam and removed some fuses to find a permanent live. Put everything back and started engine to see all the warning lights flashing up!
I checked the fuses that I removed but are all ok. One of them was the Engine Control System fuse could that have upset the system?
I sure I had the ignition turned off but am wondering if I did now.
many advice would be greatly appreciated.

 

Sometimes a weak battery can cause havoc when the dozen or so computers try to boot up at startup.

 

I would replace the battery if its the original it would be 5 years old. Thats about the time a battery goes bad depending on your local climate. Just a thought.
