i spent the afternoon wiring up 12n and 12s plugs on my t30, hooked it to caravan and hey presto everything works. fantastic. turned of ignition and the fridge still on i followed all steps for switch relay 30amp inline fuse from battery to relay, double checked everything so cannot understand why the fridge stays on with no ignition any help or ideas please

relay winding from ignition to ground,

battery to contacts then to fridge,

pull the fuse and does the fridge stop, if not wrong live,

if it stops then relay wired wrong,

got it... thanks.
