Alistair Posted October 1, 2016 Report Share Posted October 1, 2016 Morning chaps! I have a great extreme running a 1uz in my 4x4. The hydraulic fan is PWM controlled for variable speed.(100% duty is no fan speed) can I add a external earth to my fan on amomentary switch to stop my fan for water crossings to prevent damage? I mean to clarify I won't hurt the pwm driver in the ecu (switching lowside) if I do? Cheers Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2016 Report Share Posted October 3, 2016 Hi Alistair,So just to confirm, the aux output is driving low? One possible solution is to use a 3 pin switch, where switching the switch joins one pair of pins, and then another pair in the other position.Scott Quote Link to comment Share on other sites More sharing options...
Alistair Posted October 3, 2016 Author Report Share Posted October 3, 2016 Yes ign feed to one side of the solenoid and ecu is switching earth..I did consider that as a option. Might be easier if I do that Quote Link to comment Share on other sites More sharing options...
