Please ensure that the ignition switch is in top class condition that when you rock it about the ignition lights dont flicker.If this does happen the switch is probably on the way out and may need replacing. Also check to see if there is any continuity between the alternator wires and the engine earth.There should only be output between any of the three alternator wires but no output between any single one of the three and earth. If you get continuity between any of the three and earth this means the winding insulation has broken down and an alternator needs replacing.Please note connecting or disconnecting a battery when the bike is running can cause a rectifier to fail as can a loose battery connection or ignition switch that has loose contacts.

Charging System for 2000 GMC 1500 Sierra 4x4


measure battery voltage while engine running good is 13V to 14V then over charging is 17V to 18V DC
if ok battery gauge could be defect
if not ok then look for stuck pulley on alternator belt by removing the belt and turn all pulley free.

hope it help

Battery will not stay charged


Hi, Anonymous in order to check out any main electrical system, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary. "WARNING" never plug or unplug any electrical connector with the engine running !!!
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is "GROUNDED" and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the multimeter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the multimeter should read infinity. Connect both leads to the alternator multimeter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

Voltage regulator rectifier


Hi Mike, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12 volts or better after charging.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor. Good luck

Is there a wirer that runs from the alternator to the battery on a 1984 mercury capri. The car is not charging the battery and I replaced all the battery and starter cables


From the alternator the AC is converted to DC and regulated so as to make a controlled charging at all levels of the alternator RPM when the engine revs. This is to keep the high voltage of AC to DC from damaging the battery and so the regulator/controller is an important part.
So you must first check your alternator voltage/current , then the controller regulator and the battery voltage change can be seen with a voltmeter across it. Also the currrent to the battery can a be checked with an ammeter in parallel.
So check these tips and comment.

Where is the voltage regulator on a 99 mercury cougar?


The voltage regulator is a part of the alternator.If you are having pulsating issues then look for grounding issues like a corrided eyelet or loose grounding bolts.

I have the 02 vfr800 and it keep killing batteries. i think the alternator is dying but others tell me it might be the rectifier regulator. does anyone have a way of testing either or both devices so i...


hi this might help,normally if the alternator/generater fails you will get no charge voltage at all,if your bike is fitted with an alternator(most later honda models are)then you will have a rectifier and regulator,the rectifier converts the ac voltage from the alternator to dc voltage which is then fed through the regulator and then onto the battery,if the bike is fitted with a generator then you will still have a regulator but no rectifier,a generator develops dc voltage at its source so a rectifier is not needed,a simple way to test the system is with a simple digital volt meter,these are very cheap and reliable and can be got for around 20 bucks,with the engine running at about 1500 -2000rpm test the voltage across the battery with the meter normall voltage at charge should be between 13.8 and 14.8 volts,if you are getting more that this then the regulator is faulty,another way to test the regulator is to slowly lift the engine rpm from idle through to about 3 or 4000rpm the voltage across the battery should not rise any higher than about 14.2-14.8 and it should reach its peak at about 2-2500rpm and not fluctuate more than about 1 volt across the rev range,if the voltage exceeds about 14.8 or fluctuates excessively with engine revs then the regulator needs to be replaced.hope this helps...cheers ian

My 7.3 L diesel ford f-250 shows the battery light (check charge system) on in the dash. I tried to drive it and the voltage gauge started dropping into the 10-11 v range. I replaced the alternator...


You must have an older vehicle,but I am pretty sure the 7.3 was put out after the voltage regulator was put in the alternator.What you are describing is a voltage regulator on the the firewall.If this is so,replace the voltage regulator on the firewall,with a new one.This will be the problem most likely.The voltage regulator on the firewall should be kind of flat,almost square,and a wide plug,goes all the way across the voltage regulator.If You don`t have external regulator,then it is built in the alternator,and the alternator you purchased is bad.Be sure the wires on the back of the alternator are not broken anywhere.The big post ,largest wire,on the back of the alternator is the out put wire.It should go to the battery.If it does not have 13.65 to 14.25 volts on the back of the alternator,and at the battery positive post.Like I said,I believe the voltage regulator is on the firewall,if it looks like I described,then it is a regulator,replace this part(voltage regulator)and it will solve your problem.I hope this was some help,please let us know,thank you.

My charging system hasn't worked correctly since I've owned the bike....about 3 yrs. I have replaced every component in the system and some pieces twice. I've been told that there must be a power wire...


Hi and welcome to FixYa,

A couple of tests / checks:
  • +12 on the red / white wire to the rectifier even with the ignition switch OFF;
  • +12 on the black wire from the regulator and to the ignition switch only when the ignition switch is ON;
  • green wires from regulator and rectifier goes to the body ground;
  • connector terminals / pins of the 3 yellow wires from the alternator;
  • high AC voltage (>15) on the white wire from the alternator with the engine running;
  • 12.5 ~ 13.2 VDC on the battery terminal when idling;
  • 14.5 + on the battery terminal @ 4000 RPM.
Postback results of tests.

Good luck and thank you for asking FixYa.

Battery will not stay charged


Check the battery strength and then double check your alternator to make sure it's charging.. I installed 3 alternators, new off the shelf, on one vehicle, and all three were duds (4th one worked fine). If the battery does not need replacing, and the alternator is charging, double check and make sure no components are left on such as a light in the glove box.
