Could be a # of things. First is the battery up to doing the job? If you have a voltage meter test to make sure you have close to 12V across the battery then turn on headlights voltage should not drop more than about 1 volt. If so battery most likely is OK. Dirty battery cables will be the next thing to look for. Are the terminals clean & corrosion free at the battery? If you have found no problem so far your starter may need to be replaced. Do you have the ability to use jumper cables & jumper it from another battery?
If you can jump start it or put a battery charger on it & git it started again you can test voltage across the battery. with car running you should have about 14V if 12.5V or less you need a new alternator.

Where is the voltage regulator situated on a 1996 toyota hiace


have the alternator checked. The voltage regulator should be a discrete unit .....see link below

the voltage regulator is connected directly to the alternator, it is pictured in above link

No headlight on 97 T100 tail lights and running lights work


Test for voltage going into and out of the hi/low switch. If you have voltage at the headlights, check the ground wires.

Find why voltage is low to startet


Need wiring diagrams & use a volt meter,
to walk the starter circuit ,doing voltage drops
No one can tell you what the problem is,you
have to test for that

Headlight wiring low voltage


A battery's voltage is properly tested under load. This sounds like your battery is low on fluid or has not been charging properly. Not charging properly could be from low battery fluid, poor cable connections or a failing alternator. You did not state whether you tested this voltage issue with the vehicle running or not. If the vehicle was running when you observed this change in voltage upon turning on the headlights, then a bad alternator is most certainly suspect.

No power to startet when key is turned check relays they r goood can put power to starter and it will crank any idear


will your car start if you put ignition key in run postion and then put remote power to the starter to crank engine? If it will you probably have an issue with the electrical portion of your ignition switch. Check to see if you have power to the high voltage side of your starter relays. If not check for a bad fuse. If so check to see if low side powers up when key is turned. If so it means you are gettintg current from the switch. So keep checking for power all the way to the starter. If not check and replace the ignition switch.

My son's 93 corolla low beam lights went out at the same time. I checked the fuses and they look ok. Does this happen often?


It is most likely the dimmer switch,check voltage to the low beam lights,if they have no voltage,replace the dimmer switch,if they have voltage to them,replace the low beam lights.

Low Beams keep burning out! Sometime both sides. I replaced approx. 6 bulbs in the past 3 months. All other lights are working fine. No short indicated. 2002 Toyota RAV4


Hmm, That is rather whacky.

You'll need 2 (two) people, probably, unless you have a Volt-Ohm meter with really long leads.

Attach VOM (20v range DC across low beam circuit (ex: pull the bulb out and push the probes into the low beam slots). Start vehicle. Note voltage. Should be somewhere between 13.5 and 14.4 Volts DC. (If you read neg voltage, you've got the leads reversed!!!). If too high, voltage regulator may be shot.

Have someone rev the engine to, say, 3500 RPM. Measure voltage at that RPM to see if still in nominal (<14.5 VDC) range. This could also indicate faulty voltage regulator.

return everything to normal.

Oh, one other by-the-by: You're not using those HID look-a-like bulbs sold at auto parts stores, are you? They are notoriously cheap and have notoriously short lives.

Good luck.

Start vehicle, turn on low beams. with Volt-Ohm meter (VOM), m
