That's not exactly what I meant by diagnostics but they do make a scanner for the 7mgte diagnostics= a multi-meter can tell you whatever the computer has to say. Learning how to use one will save time, money and improve the enjoyment factor of owning a mostly electronic controlled 20+ year old sports car. The correct diagram is posted in the 3rd post of your thread.
If you can rebuild an engine, you got this. An electrical circuit is hardly different then an oil passage circuit or a coolant circuit. If something causes resistance (dirt/corrosion/defective part), the flow will decrease until the fluid is no longer able to flow where it needs to go and eventually something will suffer. If there was a huge hole (broken hose,stuck t-stat=broken wire, defective electronic part) then the fluid would not make it where it needs to go at all because it will flow out of the new hole instead or may not flow at all because it's path has been disrupted and now something will quickly suffer. For an electrical circuit to exist electrons must make the loop exactly as the oil or coolant. Think of the battery and charging system as the oil pan and pump, the oil starts and eventually returns to the pan, electrons start and return to the battery. The alternator keeps the pressure up. Measuring electricity is like measuring the level, pressure and condition of your oil. I really hope that kinda helps.
