BillySinden Posted November 17, 2023 Report Share Posted November 17, 2023 I have set up the relay using this configuration. using the aux output as a ground trigger on the relay. the switched 14v is coming from the ignition barrell with fuse (true ignition). i have also updated my ecu and it still comes up with fault. this is the same for the electric fan any thoughts?

Adamw Posted November 17, 2023 Report Share Posted November 17, 2023 Does the fuel pump run if you set the aux to test mode? What ecu and what firmware? Quote Link to comment Share on other sites More sharing options...
BillySinden Posted November 18, 2023 Author Report Share Posted November 18, 2023 Lastest firmware, and g4x monsoon And no it doesn’t run in test :/ Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 18, 2023 Report Share Posted November 18, 2023 Can you tell me the firmware version that is listed in >help >ecu information when you are connected. If it doesnt work in test mode it would suggest there is a wiring issue. If you unplug the ecu and switch on ignition, measure voltage on the aux 4 pin to confirm you have 12V there, provided you do, then poke a paperclip or something in and short it to ground to confirm the pump relay then clicks in.

BillySinden Posted November 18, 2023 Author Report Share Posted November 18, 2023 I’ve changed the wiring to go on aux 1&6 and that’s sorted it must have done something to aux 3&4 thank you Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 18, 2023 Report Share Posted November 18, 2023 There are 4 different tests that the fault status relates to, but usually if it is showing a fault when the aux is inactive it means the voltage on the aux pin is less than 2/3 of battery voltage - ie there is some resistance to ground in the circuit attached.

BillySinden Posted November 18, 2023 Author Report Share Posted November 18, 2023 I think that is what I was running into, I have rewired and changed the Aux inputs Quote Link to comment Share on other sites More sharing options...
