Liamnissan_sr20 Posted May 25, 2022 Report Share Posted May 25, 2022 Hi im running storm x on my SR20. Im in the testing and setup stages of my harness build and when i power up the harness im using a ignition trip relay that feeds power from the starter B terminal to the rest of the engine harness. When i cycle the key to ON, everything powers up as it should, when i cycle the key off the relay doesn’t shut off. I have narrowed it down to the boost controller, everything works as it should if the boost controller is unplugged. I have the boost controller wired 12v and ground (orange & black from link flying lead) the orange & black wire is also showing 12v. I checked the pins at the ECU and its in the correct location. Is there a setting on PC link that i need to change for orange and black (Aux 1) to be ground not positive or is that orange wire supposed to be hot and i need to supply it ground?

Vaughan Posted May 25, 2022 Report Share Posted May 25, 2022 is the boost controller 12v coming from an ignition switched supply or an always on supply? Quote Link to comment Share on other sites More sharing options...
Liamnissan_sr20 Posted May 25, 2022 Author Report Share Posted May 25, 2022 Relay is fed always on from starter B+ which then feeds the whole harness and boost controller, The trip side of the relay is ign power from the key. Quote Link to comment Share on other sites More sharing options...

The only way the boost solenoid could cause a back feed was if it still has 12V to the other side of it after the ignition has switched off. This supply relay is staying alive for some reason.
