Hey, all! I'm starting a commercial multi add on next week in a '79 Seminole and I'm trying to get as much down now as I can. I've got a (probably stupid) question about the differences between the electrical systems in a '79 Seminole vs. newer ones (approximately '00 and on). Lots of resources for the electrical system I've found online use a diagram from the newer Seminole, which show the electrical system having 6 buses (shown below). I understand the newer diagram, everything makes sense and it's pretty clear where everything is.
For the life of me, I can't find as nice of a diagram in the '79 POH. The closest they have is the alternator and starter diagram (shown below) and I'm having a hard time figuring out if it just neglects to show the avionics buses shown in the newer POH, or if the '79 model has a different bus layout that you have to decipher from the diagram. The POH is certainly light on descriptive text. My best guess is that the diagram has been altered to just show what is relevant to the starters and alternators, but I'm honestly not sure.
Does the '79 Seminole have the same 6 bus layout that newer Seminoles do, or does it have its own deal? Thanks!!
