hi,
i am trying to figure out why i don't have 12v from my mg11 v 3.0 board.
to my fuel pump relay.....
i have 13v available.
it is only putting out 5 volts to fuel relay relay. and they appear weak...
not enough to turn fuel pump on.
fuel pump led is on, ing's works
Please any ideas?
every thing else appears ok
new start up ms11 v 3.0 -fuel pump voltage only 5 v to pump?

The board is set up to switch the GROUND to the relay coil ,
with the other side of the relay coil connected to switched power
that is also hot while cranking .
