Hello again. I use my multimeter to test to battery drain. Taken all fuses out. Taken off negative connector and put amp meter through that. With yellow relay in it shows its drawing amps but with yellow relay out there’s hardly any amps drawing. 🤷‍♂️🤷‍♂️. And you can hear relay clicking in when amp meter or battery connected. Also just looked in Haynes manual and it says no.30 pin should be +( permanent live) but that seems to be earth on mine and number 86 pin is permanent live. That’s when I test voltage with no relay in
