Check all fuses for continuity. Check wires to stator for continuity and no open circuit. Use a multimeter and check voltage of battery when fully charged and check when cycle is started and revved up to about 2500 rpm should be much higher when running and revved 13 to 14 volts..Suspect a bad stator if all fuses and wiring checks good.

Lights go dim when rev engine

Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty wiring between battery positive and headlight bulb socket.
9. Weak charging alternator/generator.
10. Faulty voltage regulator/rectifier ground or overcharging.

12 RES - Control Panel Dead With New Battery

If it won't start in manual, you have a short and/or a bad control board. Make sure battery polarity is correct, did you disconnect battery charger before removing old battery? If not charger can push DC volts over 20V and can damage control board.

Headlight are dim

check output of the alternator as there may not be enough current produced to keep the battery charged. Check drive belt tension and condition.

Dodge Ram 3500, Headlights are dimmer than they should be.

Hmm. Ok this can be one of two things.
1: Check your grounds, a bad ground will kill the voltage going to the headlights. Find the wires and run them down until the wire somewhere connects to the body by a small bolt or screw. Unscrew the ground and then make sure the connection is not rusty nor painted over. You may want to be bare metal on bare metal. Thats your best bet.
2: Your second solution may be that your alternator may be dragging on the battery causing the headlights to dim. Check that by revving the engine up a little bit and see if the headlights get any brighter. If they do not, It should be the grounds. Also, check if there any other bulbs around the truck that may be out. Just like christmas lights, one bulb goes out, it effects the rest.
Hope this helps. -Steve

Does a 1993 honda cbr 1000 has a alternator. My new battery die quickly.

Yes it does have an alternator.

When you say "die" I assume you mean it goes flat quickly. If this is the case, then this is normally one of two things - either the alternator is faulty or the voltage regulator is faulty.
Faulty alternators can usually be identified by looking at the switched on headlight and revving the engine. If the bulb doesnt glow brighter when revved, this is usually a sign the alternator isnt working.

If by "die" you mean the battery fails altogether and has to be replaced, this sounds like it is being over charged and this is almost certainly a faulty voltage regulator.

However, as with most things in life, these are not foolproof tests, so unless you have a good understanding of electrical items, and some test equipment such as a good multimeter, it's probably best to take it to a workshop.

Also, Honda CBRs made in the 90s have a reputation for their voltage regulators failing often.

03 kia won't start

Hi do you have any power at all ie when you turn the ignition on do you get all the dashboard lights light up as normal and can you use the headlights etc if you can are the lights bright or not.

If you have no power at all then the chances are the battery needs replacing or it could even be that the alternater needs replacing and then your battery has run flat.

The best thing to do is either charge your battery up and then try your car again if it starts up as normal but their is a picture of the battery lit up on the dashboard then this indicates that the alternater needs replacing.

If after charging the battery you still have no power at all then this would indicate that the leads coming from the battery are loose or not connected at all.

The main problem with the leads from the battery is with the earth leads one should go to the body work you will need to undo this and check that this is not corroded where it touches the body work you can use sand paper to remove any corrosion
The other earth lead connects to the engine check this is still connected and free from corrosion.

Check also the possitive lead from the battery that goes to the starter motor check this is still connected also as this is the main lead from the battery.

You could try using jump leads from someone elses car onto your battery this way if you still had no power it would then 100% be the leads at fault.

If after connecting the jump leads you thne have power and can then start the car this would then indicate that either the battery is at fault or the alternater the way to test this would be when the car is running at night time park up agains a wall about 10 feet away with the head lights on full beam facing the wall no when you rev the engine up the lights should shine slightly brighter then when you stop revving it should go slightly dim if it does this then the alternater is ok and the battery needs replacing.

If the lights dont go any brighter then this suggests that the alternater needs replacing.

Let me know how you get on or if you need further assistance ok

Yw50 battery goes dead ==not a battery problem suggestions

Hi and welocme to FixYa,

Offhand, check the fuses, wires & connectors for looseness, corrosion or pittings/burnt marks; scrape clean and tighten as necessary.

Should the fuse, wiring & connectors check out, then the voltage regulator could be suspect. This could be checked by measuring (with a voltmeter) the battery's voltage before start, on idle and while revving. Compare readings: with engine off, battery voltage should be 12 + volts, on idle should be less than 13 volts and while revving should go high with a maximum of 14.5 volts or thereabouts. If the voltage is below 12 at idle or and will not go up while revving, then the voltage regulator would require replacement (most likely).  It must be pointed out that in some instances, it could be the stator (least likely).

Good luck and thank you for asking FixYa.

Right headlight is brighter than the left headlight

Probably a bad ground or bad connection on the headlight that's dim. Try wiggling the wires on the bulb connection if that's not the problem/ Try and find where that headlight gets it's ground.

Have a load test done on the battery. If it checks out good, take a voltmeter to the battery and have an assistant rotate the engine. If you see more than a 2 volt drop when the car is being started, the starter is heading south.
