Output status when powered off

Post by Westillo »

When using fuel outputs or h bridge out put controlling a relay with ground (and relay always has power) will the ecu ground the circuit when powered off?
Ive had this issue on another brand ecu where when i switch ecu off the relays turns on because the ecu switches to ground when off.
Im using nos brand solid state relay which is always powered on. And want to know if it will work wired this way.
Thanks

It should be a quick test with a device of your choice :)

I believe you should be ok.

I run my fuel pumps via a SSR and a "permanent" fused supply to the SSR and have never had a problem
