You can find the voltage regulator for your 1987 Toyota on top of the alternator. The voltage regulator is attached to the alternator with two retaining screws.
In my yh63 HiAce van being 1986 model that's right hand drive it's located above and behind the clutch pedal...very awkward spot to get to
The enginge computer is the V-Regulator.
No, the voltage regulator determines the alternators output voltage. That's all it does. If the regulator fails the battery level can drop to the point that there will not be sufficient charge to start the engine, but the regulator will not directly cause the engine to not run.
its mounted to the alternator which has to be removed to get to it
no it will only make the battery not charge
the voltage regulater is built into the alternator it regulates how much volts gives to the battery
You can use a voltage regulator IC/transistor that can take any input voltage (to a point) and spit out whatever voltage you want, depending on your application (in this case 380 volts) then be sure you build a regulator with the correct IC/transistor. Hope this helps!
On the top of the motor there is two of the the glow plug relay has no cover on it
Most common would be your blower motor voltage regulator, this is the part that varies the voltage to the blower motor telling it to go faster or slower. It is located up under the dash on the passengers side and pretty easy to replace. You might also have to replace the blower motor and cover though, if the regulator has never been replaced before you might have to do this. The old style regulator is not available anymore.
To make a dynamo, a small hobby motor is needed. The small hobby motor is then mounted on a board of wood and then connected to a bigger wheel. The handle is then fixed and the motor connected to a voltage regulator.
In all probability you have a bad battery or a loose connection. If the voltage drops with the motor running, you probably have a bad alternator (or generator) or regulator.
It is located inside the inner primary at the front of the motor below where the voltage regulator is mounted. The voltage regulator will have a wiring harness that plugs into the stator plug on the outside of the inner primary (the stator is located under the plug). You must remove the outer primary and the clutch basket to access the stator.
You have to drill the rivets on the motor separating it from the regulator. The new motor then mounts to the regulator and you insert the new bolts where the riverts were.
