Question about 1985 Ford Bronco
I wasn't having any electrical or charging issues with my 85 Bronco 302 that I know of until I installed a new alternator and voltage regulator. After the install, the battery would drain overnight with the truck off. I jump started it to find that it was overcharging and when I turned the truck off, it continued to sputter and try to run, even with the keys out of the ignition. I tried another new regulator, only to have the same problem. I then put the old original regulator back in. The overnight battery drain stopped as well as the truck trying to run after turning off, but the overcharging continued. I am trying to figure out my next move. HELP!!!

SOURCE: 95 F150 wont crank
the starter should be replaced. The solenoid is kikcing the pinion out but there is no contact being made to turn the starter motor. I have the exact same truck and before i changed the starter used the old starter tap trick. Tap the starter casing with a hammer and it should start turning again. hope this was helpful for you. Good luck.

It doesn't sound like a ground, but there does exist an engine to body ground strap the gets forgotten quite often. It is located at the rear of the engiine going from an intake manifold bolt tothe firewall. Check the charging voltage of the alternator at the battery posts. The charging rate should be between 13.6 to 14.2v. Remember this, The higher the voltage the lower the amps In turn the lower the voltage the higher the amps. If the alternator is charging at 14v, it should drop towards 13,even as low as 12v, depending on the battery and accessory loads.At 12v, the alt is pouring out some serious amps and running hard. This is not good for the alternator. That's the reason for 13.6 being nominal. If the alt puts out 15v, this is also harmful. Although you aren't getting the amps, the high voltage will burn up things designed to run on 12v, Like lights and radios, relays and such. I hope all this makes sense to you and is of help. Check the eng to firewall grd, Ck your charging voltage and give your battery ground a second once over at both of the cable ends, loosening the bolt on the engine end and making sure its clean. Checking the + connection wouldn't hurt. Good Luck, Ned. Let me know, k?
