shizzl Posted November 2 Posted November 2 So I run a S4 alternator in the ute, wired it up as many others had mentioned, but gave been plagued with a parasitic draw since day one. .588 draw I have a brand new optima battery in it and took time to go through a draw test. it showed nothing until I decided to pull the wire out of the back of the alternator. I’ve been told to connect the sense wire to the B+ post. I believe that this method makes the alternator constantly excited which draws power. is this theory correct? with the wire pulled it dropped the draw right down to like .078 from memory. it still charges at 14.2v like that. but I need to know the correct method to complete this so I don’t kill it. am I correct in thinking that the “R” terminal (top of the T plug” should be wired to accessory power (key on). I did have a battery light wired into the light terminal but sprint have binned that and run it through the haltech dash somehow. Quote
chris r Posted November 3 Posted November 3 I've always done L - light to dash (or haltech in your case) and s-sense to switched ignition Quote
