Nitrous solenoid activating with key off

Recommended Posts

I've come across a strange issue that I'm hoping someone might be able to help with.

For some reason, my nitrous solenoid is activating if the toggle switch is ON with key OFF and obviously no conditions being met as the engine is off and 0% TPS . If I turn the key ON and the toggle switch is ON, the solenoid turns off until it meets the conditions specified in the GP output as it should.  With Key OFF and toggle switch OFF, things are off. 

I've attached my wiring and GP output settings. Could this be a weird backfeeding issue?

 

KEY OFF / SWITCH OFF: SOLENOID OFF

**KEY OFF/ SWITCH ON: SOLENOID ON :wacko:**

KEY ON/ SWITCH ON: SOLENOID OFF

KEY ON/SWITCH ON/CONDITIONS MET: SOLENOID ON

Yep that is a back feed.

The ECU will provide a ground when not powered up so switch on and ECU of the relay will energize.

Is this an issue or is it OK to leave it as is? Sounds like it's causing the ECU to stay on while the car is off which could drain the battery. 

If it's an issue, what would be the correct way to wire up this relay for the nitrous solenoids?

As Greg mentions are you sure your 12V is actually switched. As for the solenoid to power up it has to have that 12V there.
