envmyz Posted July 10, 2005 Share Posted July 10, 2005 Some confusion on how to hook the X2 output to a relay Can someone explain this schematic to me? Only getting 5v out of it (as a ground), is X2 a ground or POS? Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted July 11, 2005 Share Posted July 11, 2005 the relay is driven to ground to engage it.in4002 is a diode.2n2222 is a transistor.1k is a resistor.the outputs on megasquirt cannot directly handle any large current or voltage loads.parts are probably at radio shack.use standard bosch relay.
