Reading 1993 Subaru KS4 Sambar Wiring Diagram

My red overlay of the BR wire connects to an ignition coil that connects to a 15A fuse. I do not see where this gets power from. That is what send power to the 15 A fuse that then send power to the ignition coil.

See the numbers 1 2 3 4 5 6 and 7 to the right of where your red line stops? On another page of the diagram you will see those same numbers in that same order, we need that page of the diagram. We need to see where #3 goes.

i am an idiot, thanks for this very simple to you tip but made a big difference for me. "See the numbers 1 2 3 4 5 6 and 7 to the right of where your red line stops? On another page of the diagram you will see those same numbers in that same order..." I was not sure what those numbers meant. Let me attempt to explain what I think this is saying. The BR( Black Red ) wire connect to position 5 on the back of the connector attached to the "Ignition Switch". It only receives power when the ignition switch is in the "START" position. I am not sure what provides power to this part of the circuit. Thanks for the tip.

It's powered through the ignition switch terminal B (battery) via the 60 amp main fuse. Under "Ignition Switch", the small circles refer to the terminals that are connected when the key is in that position.My ex once told me I have a perfect face for radio.

Legend of right of your latest picture is as follows. B = Battery IG = Ignition A = Accessory R as far as I can tell would be for Run. The way the dots work in that same section is as follows. Across the top are the words Off Acc On and Start. When in off there is nothing connected to anything. With key in Acc, notice the battery connection is connected to only the Accessory output. WIth key in on position the battery is now connected to ignition and accessory. In start position notice that everything except the accessory is powered. I really have no idea how this would work with the ignition coil only receiving power when the key is in the start position. I would assume it should be connected to the ignition circuit. If there is not voltage on that wire when attempting to start the vehicle, you may want to use a relay that is triggered by the start wire and make that also power your wire in question. What is the problem with the vehicle? When you try to start does it even attempt to turn the engine?

IG terminal of switch supplies power to the ignition coil through the resistor. The ignition coil would be supplied 9-10 volts typically. When starting, the coil is supplied 12 volts (R terminal), to make starting easier.   This is a simple breaker points style ignition system. Running the coil on 12 volts continuously would result in the breaker points contacts arcing excessively and burning up (failing).

Thanks for explaining. The B, IG, S, A and R how did you know what those letters meant? I had somewhat of an idea. This is the situation the car's starter will turn over but I am not getting any power to the ignition coil. The 15A fuse blows every time I turn the key to the "On" and "Start" position. Not sure why the "On" triggers the failure since it should not have power going to it. I need to double check that. Because it fails I can not get spark. Thanks

This makes sense why the fuse blows when the key is in the "ON" position.   Power is coming in from the from the battery to the "IG" ignition (4, position and wire BL ). What I do not understand is how did you decipher the BL wire supplies powers the resistor? I do not recognize the symbol for the resistor being used here if it is. I see a rectangle with "Fuse Box" labeled next to. This encapsulates BR No. 3/15A and BW NO. 4/15. How would you know this is referring to the resistor? Following your logic then my issue is that resistor before the ignition coil. I really want to learn how you figured that out. Thanks

The wavy line at the 3/15 and 4/15 is the symbol for a fuse.

Can you unplug the free axle solenoid? Bottom right of first pic. Just above and to right of coil. Which fuse is blowing 3/15 or 4/15?
