If the SEDEMAC Controller fails to crank and start the engine, you should: * Check the battery voltage. * Enter “configuration mode” in the controller and verify the configuration for the “Start Relay” output. Also, check that “Start Relay” output is working correctly by measuring its output voltage. * Enter “configuration mode” in the controller and verify the configuration of “CRANK DISCONNECT” method. * Verify the configuration of “LLOP SWITCH” polarity. Also, ensure that the 3+2n/4+2n switch & sensor are working OK. Check their wiring.
