The PCM should be regulating the voltage and charging.  The alternator should not have a regulator in it.

I just replaced my alternator, and installed an external voltage regulator, to bypass the computer controlled regulator, and my battery still won't charge. What could be wrong, now?

right on BILLBEAN !!!
But I still think the alternator can be connected to the battery directly with the proper amperage regulator...
I did that on my self built boat and that worked now if the battery is charging , then nevermind the ECU... Unless there is a possibility that you might burn the main cpu...
Unlikey but not impossible if there is an jndetected prblem or short...

Does a 1996 toyota tercel have an external voltage regulator

Looks like the regulator can be replaced. But it is on the backside of the alternator. You may not be able to find it.. Without buying the alternator.

New battery and new alt. but still doesn't charge 1999 f 150

check that the new alternator has the right type of regulator for it . If you have an internal regulated alternator on a car that has an external regulator then it will not charge . Both look the same but it may have int -reg on the housing some where.

Following replacement of an alternator on my Toyota Surf 3.0 td import the new one now becomes extremely hot, any ideas what may be causing this

there is an uncontrolled short in the system that is allowing the alternator to exceed it's designed out put. You may have not used the correct regulator with the new alternator or the new alternator needs an external regulator for current control where as the old unit had an inbuilt regulator. check that you have connected the alternator as required for the new one and not for the old one.

There are 4 different types of alternators found on the years and model ranges covered in this information:

  1. Rear Terminal, External Regulator, External Fan Alternator
  2. Side Terminal, Internal Regulator, External Fan Alternator
  3. Leece-Neville 165 Ampere Alternator
  4. Integral Rear Mount Regulator, Internal Fan Alternator

Rear Terminal, External Regulator, External Fan Alternator
This unit utilizes a separate, external electronic regulator. The regulator is non-adjustable. The rear terminal alternator was standard equipment on 1987 trucks, and can be found on some 1992 motor home chassis models equipped with the 7.3L diesel or 7.5L gasoline engine.
Side Terminal, Internal Regulator, External Fan Alternator
This unit was optional on 1987, standard on all 1988-92 models and standard on 1993-96 models equipped with the 4.9L and 7.5L engines. The regulator in integrated within the alternator body and is not adjustable.
Integral Rear Mount Regulator, Internal Fan Alternator
This alternator is standard equipment on all 1993-96 models equipped with 5.0L, 5.8L gasoline engines and 7.3L diesel engines (except the 1996 F-Super Duty models).

  1. Disconnect the battery ground cable.
  2. Remove the adjusting arm bolt.
  3. Remove the alternator through-bolt. Remove the drive belt from the alternator pulley and lower the alternator.

Some engines are equipped with a ribbed, K-section belt and automatic tensioner. A suitable tool must be made to remove the tension from the tensioner arm. Loosen the idler pulley pivot and adjuster bolts before using the tool..
  1. Label all of the leads to the alternator so that you can install them correctly and disconnect the leads from the alternator.
  2. Remove the alternator from the vehicle.
  3. To install, reverse the above procedure. Observe the following torques:

    Pivot bolt: 58 ft. lbs. (78 Nm) Adjusting bolt: 25 ft. lbs. (34 Nm) Wire terminal nuts: 60-90 inch lbs. (6.8-10.1 Nm)

My alternator is not charging the battery. Both are new, new belt. The belt is tight, the fuse is good.

the wiring is bad. go through your harness from your alternator to your external regulator (if the alternator is externally regulated) then that to your starter solenoid and to your battery. if there are any cracked wires, that could be the problem.

I had to replace my alternator and voltage regulator, (external) and I'm not getting any charge to the battery. I'm wondering if I simply need an external ground or do I need to replace the wiring bundle...

where did you buy the new alternator? Are you sure the alternator is good? Have the alternator tested before you spend time/money on your other components. If your wires are damaged or corroded, that's another problem.

Need wiring diagram for 1967 camaro v8 changed from external regulator to alternator with internal regulator

I am assuming you are now using a 1976 style GM alt.
The most common and popular model.
You need one 10 gauge wire from the battery to the alternator output.
This can be run directly from the battery +.
Run a short 10 gauge wire from alt output to large wire at regulator plug on alt.
Run small wire on alt reg plug to Bat light wire.
A new alt regulator plug pigtail can be bought at any parts store and is recommended.

The existing regulator should have the connections marked.
One of those wires will be the bat light wire if needed.
If you have a amp meter or voltmeter in the vehicle.....use your existing large output wire (usually red) to hook up to the new alt output connection.
