Have you downloaded the TM?I have a friend who has a 831, he has power at the convenient receptacles but none on the main power lugs ( in any configuration), we did find one burnt relay behind the control panel, replaced it no glory... anybody run into this or have any ideas??
Have you ever seen this gen set work right? Is it new to you?
What relay did you find burnt.
Are you sure that you replaced it with the right relay? K12, K14 and K15 are not all the same relay.
Do you know how to use a multimeter?
Can you read a schematic?
