I have a 2002 ford ranger 4.0 4x4 ext cab auto with 195xxx miles
Ok this is what’s happening:
The truck voltage keeps dropping. I put a volt meter on it and it reads 12.00V at the lowest with all the accessories running, but it doesn’t stall. The battery and the alternator are good.
I started pulling fuses with the voltmeter on it and I didn’t see any improvements in the voltage
The first sign of trouble was a 75A fusible link that blew out the one the lets the alt. charge the battery.
This is what stopped working:
1. Cruise control only works when it feels like it.
2. Now I put the truck in 4wd high or low and it stays in 2wd and the relay by the passenger door just clicks on and off and just keeps cycling on and off till I put it back in 2wd.
I hope someone can help me I can’t afford to take it to the shop. Thanks
