Hi Gilly and JimF, you have given me lots of home work again , i Will look into it and let you know , I can not recall the battery has been wrongly connected but I have had some boost in the past ( battery was dead lots of time but that problem has been found thanks to you. ( the make-up mirror in the rear headliner had a broken micro switch)
What would happen if there has been a reversed battery hookup ?

I will copy the scedule for the control test light and will build one this week.
Will get back to you shortly , THX good to know there is nice and proffessional help out there !!

Ben
