Adam Marone Posted December 10, 2016 Report Share Posted December 10, 2016 Hi,A little puzzled on this one. I have a g4 storm with Aux 7 currently set up to drive a boost control solenoid (mac valve). After not being able to add boost over normal spring pressure I ran some voltage checks on the Aux 7 output and found this:Whilst engine off, ignition on;set to "boost solenoid" @20hz: reads 10.8vset to "test (on)": reads 0vset to "off": reads 10.8v No sure if it's related but whilst moving between these settings I can hear my idle motor click each time (engine not running but ignition on).Sounds like it might be a wiring issue but not quite sure where to start so any help is appreciated.

Simon Posted December 12, 2016 Report Share Posted December 12, 2016 When test is on you should see 0 volts as the drive will be turned on and providing a groundOff the drive is floating and you will see a voltage.As you change the state of test on/off you should hear the BCS clickIt should have no impact on the ISC.Are you sure AUX 7 is wired to the BCS?
