I'ld be looking at the wiring (maybe a break or fell off the connection) near the oil pressure sender but that's just a guess. our bikes vibrate

    I have same problem with my 2000 fatboy, but intermitant. When the engine light comes on, the speedo goes down to aprrox. half what i'm running, then i turn on 4-ways, and the speedo dial jumps up and down to the beat of the signal, until it stays up at accurate speen, and engine light goes out Often i'll be driving and look down at speedo, and its in trouble mode. Also not sure but I think its chewing up batteries fast, may not charge when the engine light is on. I was wondering if you solved your problem.

99 Blazer V6 4x4 Intermittent start problem New battery Alternator? good Start a few times then won't, no sounds/lights Voltage read low Charge battery and it's good for a few days Any suggestions


When the vehicle is running check voltage at the battery . should be 13.1 to 14.1 volts , if not the alternator isn't charging . Doesn't matter if the alternator is new , has to have B+ voltage on the heavier wire connected to back of the alternator . The other wire connected to the alternator comes from the PCM/ECM . Is the Battery symbol light on when vehicle is running ?
The powertrain control module (PCM) or vehicle control module (VCM) turns the generator ON or OFF, by applying voltage to the generator control/monitoring circuit 225 (RED). The regulator in the generator also requests the charge indicator located in the instrument panel cluster (IPC), using the same circuit. When the regulator monitors that either a voltage high or voltage low condition exists with the engine running, a ground path to the PCM/VCM will be provided through the generator control/monitoring circuit 225. The PCM/VCM then sends a serial data message to the IPC requesting the charge indicator to be turned ON. The IPC monitors serial data messages from the PCM/VCM, and turns the charge indicator ON when requested. It mite be best if you take your vehicle to a qualified repair shop , unless you like making parts stores rich , buying unneeded parts .

When starting sometimes you will get a click.jump start it and it fires.battery has been replaced.


The click is the starter solenoid pulling in, but the battery does not have enough charge to crank the engine. If it is a new battery, that indicates it is not charging properly, or being discharged while the engine is not runnng. So then, if the alternator warning light is OK, and is not lighting up while driving, the voltage regulator on the alternator is faulty. This allows the battery to discharge to ground whil the engine is stopped.

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

Alternator or Voltage Regulator or Other?


You will need to test the charging system. Try this simple test, hook a voltmeter to the battery and check the voltage with the key turned off. Should be 12 volts. Now start the engine and note the volt meter reading at idle, it should go up to about 13.8 - 14.2 volts. Rev the engine up and note what happens. If the voltage is low at low RPM 12V and then goes up with more RPM like you stated it could be the regulator or the alternator. Start by switching out or trying another voltage regulator. If this does not fix the problem you will need to test and repair the alternator. The alternator out put can be tested by bypassing the regulator. This requires special equipment and know how. I hope this gets you

Alternator or Voltage Regulator?


As a general rule, voltage regulators either work or do not; either-or.
This leans more to the alternator. Hook up a volt meter to the battery. Check your voltage engine off, then start it. watch the meter, if it stays below 12 volts and then suddenly jumps up when you reach 2500 rpm perhaps it's the regulator, if it slowly climbs as you describe with the lights your alt may be weak.
Do you have a lot of lights and accessories that stay on? Especially lights-extra lights can put quite a drain. Good luck to you!

1995 explorer new battery new alternator battery light still stays on battery goes dead within-2 hours of driving any hints top look for?


Hello, the battery light on your Ford is controlled by the voltage regulator. If the light is on it's indicating the battery is not charging, and is being discharged. If you have a volt meter you can test at the battery. With the engine running the voltage should read at least 13.5vdc. If it's lower than that, the alternator is not charging, or the charge is not reaching the battery. Another simple test, is remove the negative battery cable, if the engine dies the alternator is not charging. Autozone will test your alternator and your battery for free, if you do not have any test equipment. If you just replaced the alternator and it failed the test, it should be under warranty. Same with the battery.

I hope this information is helpful.

Recently having problems with my 2000 Fatty not holding charge. What should stator be putting out on voltage meter? Voltage meter climbs as rpms go up, I would presume that this indicates stator ok? Bike...


First, take your battery somewhere and have it load tested. Fat Boys are tough on batteries as the battery sits in the "horseshoe" oil tank and is subjected to high temperatures due to the hot oil in the tank. Battery life is typically two years although I've seen some go longer and some not last that long. Have the battery tested before you start spending money.

To check the stator, you unplug the regulator at the engine case. Down inside the plug you'll see some electrical connectors. Connect a DVOM (digital volt ohm meter) to these connectors (one lead to eac pin) and put the meter in the 50 volt or higher range AC voltage. This is important that your meter be set to measure AC voltage because at this point, the voltage is indeed an Alternating Current voltage coming out of your alternator. Start the engine and bring it to a high idle. You should be reading over 20 volts AC. The book says that you should read 12-18 volts per 1000 engine RPM. If your engine is turning 2000 rpm, your meter should read 24-36 volts AC.

To test the regulator, first charge your battery to a full charge. Then connect your DVOM across the battery, red to positive, black to negative. Put the meter in the 20 volt DC range. Start the bike and bring it to a high idle. The voltage will start at somewhere around 12.5 volts and climb to about 14.5-15 volts. This would indicate that the regulator MAY be alright.

Now, have you changed any of the lights on your Fat Boy? I've seen people change and add lights to the point where their alternator could no longer put out the current necessary to handle the load. If this is the case, you may need a higher out charging system.

I don't know where you're located but $260 seems quite high for a voltage regulator.

Gone through 3 batteries, they drain until they won't charge, and have to get a new one


It sounds that you have a problem with your car alternator charging system: it should be indicated by a charging warning red light being permanently on.
If you have a multimeter, you can check the voltage at your battery terminal:
- with motor off, the voltage should read around 12.8V with anything under 11 v indicating a 'shorted' bad battery.
- with motor running, the voltage at the battery terminal should be around 13.8V with any reading above or below that indicating that your car alternator or regulator is faulty.
ps. I am really surprised that you needed to get 3 replacement (new) car batteries: this can only be caused if you are actually 'cooking' them: this would be caused by your alternator regulator allowing a high (over 14V) voltage and thus 'boiling' the electrolyte away and damaging the battery plates!

Vehicle: '97 Nissan PU, alternator


ok we have four connections at the alternator( black wire is ground) (white with blue positive direct from the battery)
and two wires connector in the regulator(yellow with black that goes to charge indicator the red light and goes to fuse 7 10a fuse block inside) the blue with yellow goes to fuse 65- 7.5a in the left fron engine comparment fuse box))#1 check for ground at the black wire= #2 check for positive at the white with blue wire (allwas with power) this wire is protected with 100a fuse is in the left front engine comparment fuse box,
remenber== check the 100a fuse
and the two fuses that protect the regulator.
when you turn the ignition switch to the on position power goes to the alternator by the yellow black wire and activate
the alternator to work.
