@Dave many thanks for that! Hoping to check the plug tonight with a multimeter as it was tipping it down last night!
@dr_broon Thanks mate. That's interesting, have you checked your earth straps? I changed mine and cleaned up where they attach to the body and it helped things with the electrics. I replaced the wires in the top two photos in this thread: (there is another thread which shows another earth if you have vtec but i cant find it)
