I just bought a 85 bronco it had a wiring problem i tracked it down the wire coming out of the alternator on the stator connection doesnt lead to anything the it has a connector on the end but i dont know where is it supposed to lead to i thought it would go to the regulator but it doesnt

Is it getting fuel? try spraying some starting fluid in the carb, and see if it'll start!
if so, fuel pump may be bad!

You can check the alternator with a volt meter. With the engine at idle you should have 13.5-14.5vdc at the battery...turn on your headlights a/c and blower motor on high...to test under a load.

There should be a pair of wires going to it to supply the field coil voltage( this is the voltage applied to the field coils to produce the magnetic energy to generate the power in the stator assembly)...there shold be 12 volts going to these wires

I looked at my schematics, and they don't show a relay. They do, however, show two ground wires coming out of the tailgate window switch. There is a ground wire for the "up" side of the switch, and a ground wire for the "down"side. These would be color-coded black, and I think that it is worth checking to make sure you don't have a corroded /broken ground running from the tailgate switch. If only one grounding wire was broken, the window would operate in only one direction. Both dash and tailgate switches share the same wiring circuit, and these wires are "hot" all the time. It's normal when you get both sides of the motor leads at 12VDC when neither switch is activated. These switches function by switching off one of the two motor leads, and connecting it to ground, thus allowing power to flow thru the motor windings. Of course, reversing the polarity on a DC motor will change the direction of rotation, so changing which black lead is switched to ground gives the up or down direction to the motor.. since you can read schematics, you might check out ebay for a used Haynes manual cheap. hope this helps

BAT attaches to the battery charging wire. GRD is ground wire. STA is stator. FLO is probably FLD or field wire connection. It would help immensely if i knew what year and model you were working on. I imagine it is a 300 straight six possibly in a ford f150 or bronco.

turn your vehicle on, disconnect the battery, both terminals(while truck is still on) if it dies on you, then either the alternator is bad or wiring is wrong. if it stays on, then you may have a bad battery or voltage regulator. Check the voltage on the battery before you turn it on(should be from 11.5v-12v), when you turn it on if the alternator if working properly you should have around 13v-14v.

you need to put a chevy alternator with a built in regulator on it.
You need a 3 wire alternator. Two wires go to the battery and one wire goes to anything connected to the ignition switch.

one cavalier i worked on had a loose wire on the starter solonoid where the battery lead is hooked. have also had corrosion and broken wires on other gm cars do the same thing
