cashpoint Posted March 30, 2005 Share Posted March 30, 2005 What voltage does the ECU run on? I've created a (never thought my GCSE Technology would come in handy) circuit to run ETTC running through the active spoiler button but i need to know the voltage for the transistors that will be used.

Guest Terry S Posted March 30, 2005 Share Posted March 30, 2005 depends on the load. Around 13.4-13.8v. Can dip below 12v on idle Link to comment Share on other sites More sharing options...
SimonB Posted March 30, 2005 Share Posted March 30, 2005 That's the voltage of the supply to the ECU, which isn't necessarily the same as the voltage used for the lines you're talking about that control the various actuators. They may be 12V, or they may well be 5v say. It might say in the electrical manual on mkiv.com. Link to comment Share on other sites More sharing options...
