Electrical fuse problem

Did you replace both diodes?
You can only get battery voltage direct thru these diodes if they go short circuit. If you remove the fuse marked 11/12 on the diagram and the power goes off then the problem is a diode.
With the run/stby switch in the run position there the wiring goes nowhere.
Pull out the master switch and using a DVM check wire no KPB18 to KPB10 if there is 28v on this point the only place it can come from is the diodes.
