So I decided to start at the wiring of the central locking unit. Ive already verified fuse 9 25 and 26 are good in relation to the units power. I’ve never used a multi meter and I’m trying to make sure I’m doing this correctly so any help will be appreciated. I’ve attached a picture of my multi meter settings can anyone confirm this is correct I should be on dcv 20? & do i have the red and black wires in the correct places? (Because I’m only testing for 10vs? Also per the manual am I doing the actual test correctly? It says pin 2 and 4 are hot I’ve put the red wire into those pins and it’s showing the black wire just sitting on top the plastic at a certain spot? I’ve tested both 2 and 4 if this is the correct way with the key off and key on accessories power both pins tested dead.
