I have a Seaward
princess 3 burner with oven
. The power for the burners can be interupted by the cover switch. If it gets bent no power to your burners. You also have the selector switch which diverts power to either the top burners or the oven but not both at the same time. By deactvating the little side catches the entire burner assembly can be lifted up and power measurements can be made at various switch points but everything should be accessable from those points.Be carefull, 120 volts under the cover that is over the switches can bite. Usually if the installation
was properly done, power will go from a breaker dedicated for the range in the ac switch panel. If there isn't, it may have been installed with a fuse of some type. I think it should be rated at 20 amps. I would gladly email
you a copy of the manual but it is on my boat which I just left. Back in the middle east for one last year.
