Hi everyone

Any suggestions .I’m no mechanic :joy:

Hi and welcome to GTOUk

Let’s see some more pictures too , the folks on here love pictures , I would be checking earths to start with for lighting issues , a faulty dimmer switch for the dash lights could also be an issue , for the rear lights check your rear lamps aren’t full of water , it’s not uncommon , again this will cause havoc
