Geoff Posted March 26, 2022 Share Posted March 26, 2022 My MK5 seems to have a battery drain of around 0.5 amps per hour and I have found removing fuse 21 stops the drain. I also hear 2 relays click when I remove or insert the fuse. One relay for the interior lighting which is R17 on the fusebox I believe and another relay which is behind the drivers side heater vent away from the fusebox. It's a genuine green Ford relay. Can't seem to see what circuit it powers, does anyone know? Thanks Quote Link to comment Share on other sites More sharing options...
