Hello,
1992 Ford Ranger XLT with 2.9 V6. My voltmeter was showing low voltage at 12 volts with the battery warning light recently. I smelled electrical burning one time. I replaced the voltage regulator (and brush assembly) because my multi-meter indicated a low reading. It didn't fix it. Then this weekend it was popping 15 amp 'alternator field' fuses. Now the truck won't start. It just cranks. I checked engine bay and crawled under truck, I did not find any exposed or damaged wires.
A few troubleshooting questions.
1. Is it is safe to disconnect alternator and fuse and see if truck will start?
2. Is it true you can use a compass to find a wire fault?
3. Will bad alternator keep truck from starting altogether?
