@jadonlyon - If the El Capitan Diagnostics works then SMC’s microcontroller is working. There still could be a input issue which can even be the MagSafe chargers one wire comm within the MagSafe connection. I would clean the MagSafe socket so the dirt is not interfering with the contacts (clean the grey body area and the contacts). You may want to install [link|https://www.coconut-flavour.com/coconutbattery/|CoconutBattery] onto your boot drive as it will offer better info on what’s happening with the charger, battery and the charging logic on the logic board. As it’s polling SMC you also get another view on what’s happening, info is being passed by the batteries microcontroller like the batteries age and some of the power values.
The issue is within the Boot ROM EFI programming when Apple updated it, they never fixed it leaving you hanging! As the system was dropped a few years later and not many people realized the loss.
@livfe - SPI issues often stem around the SPI connector that is used during the manufacturing process and left on the logic board. Directly across from the battery connection on the other side of the logic board you’ll see it, just sitting there! The issue is being so close to the edge it’s not uncommon for a liquid spill to short out some of the contacts or solder pads. If it’s spoiled I just desolder it and retin the pads so they are not causing a short. It’s not needed and many newer systems don’t have it (still having the pads not the connector)

The three beeps is a memory issue and if you have a SPI problem it’s often likely the RAM chips have a bad connection as well here. Reflowing them will likely fix the RAM error or you’ll need to replace one or more of the chips. Again, look for spillage carefully run a placket between the pads and clean with IPA first sometimes that will fix things enough to pass POST. I would still reflow the chips to address a cold solder joint risk.
