How much does it cost to replace an alternator voltage regulator?
A new alternator voltage regulator will cost you anywhere from $40 to $140 for parts, heavily dependent on the make/model of vehicle and whether using OEM or aftermarket parts. The cost of parts doesn’t sound so bad, but since most voltage regulators are housed inside the alternator, expect to pay around $140 to $240 in labor.
Where is the voltage regulator on a car?
The location depends on the make and model of the car. It will be either inside or next to the alternator housing. Ford is one brand that mounts it next to the alternator. Those mounted adjacent to the alternator need extra support, which is provided in the form of a harness.
What should the voltage be on a Honda alternator?
I also ran across a Haynes vehicle manual that states that the voltage should be around 13.5 V – 15 V, but it is not always this way. The alternator that I bought was new from Honda and not re-manufactured (the cost was just over $470.00), the part number is 31100-5A2-A02 (Made in Japan). Here is a side picture and install picture:
How to convert an alternator to one wire?
The internal electronics are bypassed. 2. Modify one of the brush connection points so it is removed from the alternator B+ output terminal and is instead connected to the alternator chassis ground. One-wire alternator, end cover and armature removed. Note the three-prong connector that’s integrated into the regulator. The regulator modification
Why would an alternator overcharge?
Over-charging is caused by the voltage regulator driving the alternator too hard. There’s two possibilities for this condition. The voltage regulator is shorted, which is fairly uncommon, or the control wire going to it is grounded.

The alternator is mounted to the engine, either the front or the side depending on the vehicle. Alternator Removal Match it Up! Alternator Installation. Finishing Up.
How much volt alternator should produce?
An automotive alternator generates electrical power to run the engine and charge the battery. An alternator that is putting out a reduced charge will eventually cause the engine to stall and not properly charge the battery, which can cause starting problems. An alternator should put out between 13.5 and 15 volts of power.
Can voltage regulator cause starting problems?
The voltage regulator is responsible to assure a proper voltage when charging the battery. The only case when the voltage regulator keeps a car from starting is if it was faulty and the battery was not charged. Because of this issue, when the battery is drained, of course the engine will not start.
