Scott Posted September 11, 2015 Share Posted September 11, 2015 As above. Need to test a boost solenoid and I'm wondering if it's safe to hit it with 12v to make sure it's operating. I'm guessing they are but I wasn't sure if the controller would maybe output 5v for some reason. Thanks Quote Link to comment Share on other sites More sharing options...
Ric Posted September 12, 2015 Share Posted September 12, 2015 does it not have any markings on it for the voltage? i wouldn't blast it straight off. it will use varying voltages to control it i expect? Quote Link to comment Share on other sites More sharing options...
TheTurtleshead Posted September 12, 2015 Share Posted September 12, 2015 Which solenoid is it? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 12, 2015 Share Posted September 12, 2015 If you have a GOOD multimeter measure the resistance of its coil. Ohm's Law will then say what current it would draw at 12V and you can see if it is sensible. I suspect it WILL be a 12V one though if you feel lucky? Can't you just look at the voltage coming out of the circuit that controls it? Or are you trying to utilise a random solenoid in a different circuit?

Marcus GTE Posted September 12, 2015 Share Posted September 12, 2015 Scott is helping me with my Sard Trigger, so that's what solenoid it is. chris, is the issue with testing the voltage sent by the boost controller not that it only sends the signal to actuate once it has reached the preset value? I.e 1.2 bar, making it difficult to test while standing over it. Quote Link to comment Share on other sites More sharing options...
Scott Posted September 12, 2015 Author Share Posted September 12, 2015 As above, I can't find any voltage info. The controller is 12v as it's obviously in the car system. I don't believe the voltage will vary as it'll be an on or off operation, quickly oscillating between on and off to control the boost.

Chris Wilson Posted September 12, 2015 Share Posted September 12, 2015 I would go so far as to say it WILL be 12V , but as you say, it will be pulse width modulated. I am thinking of bringing a cheap pulse width modulation tester to the marketplace, so people can test coil packs, injectors, drive by wire throttle motors, and of course, PWM opersted solenoids. i have got as far as designing a cheap to make PWM oscillator, and am working a FET power device for switching that people can't blow up Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 12, 2015 Share Posted September 12, 2015 I would say its definitely pulse controlled, as in order to control boost pressure you cant just throw 12v at it, as all it will do is open or close fully. Quote Link to comment Share on other sites More sharing options...
