Hey guys, a couple weeks ago my jeep went out with an electrical issue. It’s an ‘87 L6 Carb. I’ve replaced the ignition coil, ignition coil connector, and the ECM. The thing I’m seeing is when I turn the key, it cranks, but the tachometer doesn’t jump up and down like it’s supposed to. When it first happened it smelled like rubber which would point to the alternator. Also getting battery checked as well as the alternator. It doesn’t run by the way. I got it to fire and run with jumper cables, but when I took them off it died making me think it’s the alternator. Last thing to note is that it doesn’t need a crank position sensor. Thanks.
