ECM Power Source Circuit
DESCRIPTION When the power switch is turned to on (IG), the auxiliary battery voltage is applied to IGSW of the ECM. When the transistor in the MREL circuit operates, current flows from the auxiliary battery to ground through the drive circuit of the EFI-MAIN NO. 1 relay, thus operating the relay wh
