Wiring the engine compartment on my 1973 firebird with built in regulator on my alternator witch wires go to alternator then to starter to keep the battery system charching ? the system is not charching ang car dies out then needs jump started. Please help the unexperienced !!

Common Problems That Trigger the P052 Code

• Defective Alternator
• Defective Alternator wiring or connector(s)
• Defective B+ battery cable from Alternator to battery
• Poor Charging System ground(s)
• Defective PCM wiring/connection to Alternator
• Defective PCM
• Defective Voltage Regulator
• Large Parasitic battery drain
• Defective Battery and/or cables

Common Misdiagnoses

• Battery
• Starter

Check the condition of your battery cables - are they corroded/have broken wire strands? Also check where the negative battery lead attaches to the engine/bodywork.

Check all the wiring for breaks and tightness - a small earth wire can be loosened and retightened to create a better earth. Corroded power wires can struggle to supply the correct voltage - remove and clean whatever you can find.

It's unlikely to be your alternator as you say it has been checked - the voltage regulator is built into the alternator so it must be okay.

A parasitic drain can be difficult to find. Try switching off everything - radio, heater ... the next time you start the car. If you know somebody who has a voltmeter and knows how to check for a power drain .. ask them.

The link below shows a Saturn PCM (it may not be your actual model..). Check all wiring around the PCM

It only comes with an internal alternator. I believe it has a regulator mounted "externally" in the motor compartment. On modern alternators the regulator is smaller and built in and is "solid state" no moving parts like the regular the car came with. Research a conversion kit - you can hook up a modern alternator but you have to do something with the regulator wires. Hit a classic oldsmobile forum for guidence.

I believe the regulator for that vehicle is in the PCM ,if it failed you are looking at a $$$$ part. You can use an earlier regulator and leave the control module alone.Like a 1985 diplomat ,have to get the pigtail for the regulator also,then run the 2 white wires to that instead of the PCM

Bad voltage regulator. Usually built-into alternator.
Start car and unplug battery, if it dies your alternator is dead. Get new alternator. If car keeps running, get a voltmeter and check voltage coming through - should be higher than 12v but less than 18v. Any other number means your voltage regulator is dead, cheaper to get a new alternator.

Sorry iam a thick brit having problems with your spelling which as we all know we cannot spell in the UK or pronounce aluminium or tomatoes so the man to ask is emmisionwiz as hes a ford dealer fitter with enough years under his belt to know exactly what you need to know ,so try a direct question ,but for this year with a seperate regulator why not try a alternator off a later model with a built in regulator ,as for the starter motor then a wire from the contact switch on the back of the key switch that has power when the key is turned to the start position and this wire goes to the small terminal on the starter motor .I do not the facility of a fancy pen thing attached to my computer that i can draw a quick pic for you .

Hi, there are 3 fuses the the alternator needs to charge the battery. These may be inside the car or in a box in the engine compartment. They are named IG1, ECU, and ALT. If you have trouble finding them, please get back to me.

VOLTAGE REGULATER IS BUILT INTO ALTERNATOR SO CHANGE THE ALTERNATOR.

CHECK ALTERNATOR POWER FEED WIRE AND VOLTAGE REGULATOR WIRES FOR EXPOSED WIRES SHORTING TO GROUND.CHECK BATTERY POSITIVE CABLE FROM ALTERNATOR TO STARTER. LOOK FOR SIGNS BURNT WIRES.YOU HAVE POSITIVE BATTERY CABLE SHORTING TO GROUND.OR STARTER SOLENOID OR STARTER SHORTING OUT.TRANSMISSION NEUTRAL SWITCH OR IGNITION SWITCH WIRES SHORTING OUT IGNITION.

Replace the starter,it is a low geared starter ,witch has contacts,instead of brushes,if I am correct you can sometimes tap the starter while trying to start,and the starter will turn the engine over,use a hammer,do not slam the starter,it will break the magnets in the stater.

These trucks do have a regulator. But most importantly check all of your grounds. One bad ground can mess up an entire electrical system. Especially the charge.
