Question about 1993 Ford Ranger SuperCab
Alright I've bashed my head around for 2 days on this one. My ranger's volt gauge was fluctuating intermittently the other day. Finally by the end of the day the voltage was real low and the lights were all dim at night. Took the alternator in to be tested, they said it was bad. I put the new one on same thing still happening. I got a new belt thinking maybe it was slipping, still didnt fix the problem. I checked all wires in the engine compartment. Starter wires, solenoid wires, Power Distribution box fuses / wires, alternator wires, everything passed with nothing more than 0.1 ohms resistance. By this point I'm getting extremely frustrated. Inside the car I try banging my fist on the steering wheel, and sure enough the voltage comes up and it starts charging, only to stop again after about one minute. I try banging some more and after a while get it to start charging again, then it cuts off after a while again. I'm assuming its a loose wire / connection in the steering column. I do know my ignition switch is loose but this has never been a problem before and its been like that for years. Plus when I did a volt test at the alternator plug that leads from the ignition switch it always shows 12V when the key is "on".
