How can i find out if the voltage regulator is dead?? an where is it located on a 84 toyota tercel

SOURCE: location of the starter on a 1995 toyota tercel?

you should be able to follow the positive battery cable to the starter. countrycurt0

12 volt is actually a misnomer of sorts... it's actually closer to 13.8 volts i believe. if the voltage regulator is not working right you could very well be frying the battery. replacing it is the cost of the alternator + labour (unless you do it yourself).

Hello! I too am PA St Insp Mechanic.

Here are some suggestions:

Note that the Fuel injection computer starts to cease to work properly at 10.5 VDC. This leads me to a voltage issue. You mentioning that the veh has bright headlamps may be consuming more power than the alt can deliver, with the heater, the lights and the other "normal" draws.

Test the alt output with a voltmeter, plus to plus, minus to minus, at the battery. You should read 14 + volts with all of the above mentioned accessories on, at idle. 11-12 volts = bad alternator, unless the belt is real slipping bad. 14.4 is the spec.

Also, the Voltage Regulator in inside the alternator.

Glad to provide assistance to you; please rate my help with a FixYa, I would be very grateful.

Try to put a relay on every bulb to prevent burning, and also check the bulb socket make sure it is not loose.
