Reduce 67 volts to 48 volts dc


Just google for voltage regulator 48 V and you have lots of solutions. Be aware of the current going through a regulator. To reduce almost 20 volts each ampere will generate 20 Watts of heat, unless you use a switching regulator.

Hi would heated grips added to a honda transalp 600 cause the batterie to boil.thanks


No--but.... Heated grips will only put an added load on a battery, and that won't cause boiling of a battery. What WILL cause a battery to boil is overcharging or charging at too fast a rate. Now, then--when you add heated grips to the bike and you make a mistake somewhere in the wiring, you can affect the charging rate, and it's possible that a voltage regulator/charging system sees more current being drawn than it's used to and it's trying to replace that current as well as charge the battery, and it's feeding a higher voltage/current to the battery than was intended by the designers. You can check this out--put a voltmeter on the battery terminals, run the engine, and turn on your heated grips. A normal charging voltage for a vented lead acid battery should be about 13.8 to 14.4 volts; yours may go a little higher. If you're seeing a lot higher than 14.4 volts, you either have a defective voltage regulator or perhaps such a bad battery that it's screwing up your charging circuit.

What or how does the battery get its charge


Most bike have an alternator driven off the left-hand crankshaft shaft.
This turns with the engine, producing the AC charging power.
This power then runs through a voltage regulator, that both converts the the AC voltage into DC voltage, and regulates the amount of voltage flowing into the remaining electrical system.

Now, you did do the first step correctly.
DC volt meter to battery terminals to see if you get 13-14 volts DC with engine running.
Next, locate voltage regulator and unplug connector for wires coming FROM the regulator, and hook up the DC voltmeter.
With engine running, you should have 13-14 (or so) DC volts.

If not, locate and unplug wires coming from alternator to regulator, and hook up AC (note change from DC to AC) voltmeter.
With engine running, should have AC voltage (this could be 20-40 volts or more).

This will let you know where the problem is, and what needs to be replaced.

Erratic speedometer and odometer when under throttle, just replaced battery because of acid comming out of it, is this a voltage regulator problem


To test the voltage regulator, with a fully charged battery in the bike, use a digital volt ohm meter to check the voltage output of the regulator. Put the meter's function switch in DC VOLTS with a range of 20 volts or higher. Connect the red meter lead to the positive post of the battery and the black meter lead to the negative post of the battery. Start the bike and bring the engine to a high idle. After a minute or so, your meter should read 14.5 to 15 volts. Any higher, you may have a bad regulator.

Good Luck

yes, it could be the regulator or the stator in the alternator.

To check the regulator, fully charge your battery and reinstall it in the bike. Now connect a DVOM (digital volt ohm meter) "across" the battery by connecting the red meter lead to the positive post of the battery and the black meter lead to the negative post of the battery. Put the meter's function selector in DC VOLTS, 20 VOLT OR GREATER range. Start the engine and bring the engine to a high idle. The meter should read 14.5-15.0 volts. If not, you need to check the stator.

Find the stator plug where the regulator wires plug into the engine cases in the front of the engine. Unplug the wires and look into the engine side of the plug. there will be two contacts. this is where we'll be testing the output voltage. Put your meter's function selector switch in AC VOLTS, 50 VOLTS OR GREATER RANGE. Notice this time you're measuring AC VOLTAGE not DC voltage. Start the engine and bring it to a high idle. Stick one meter lead (either one) into on contact in the engine side of the plug and the other lead into the other contact. Do not allow the probes to touch each other or the side of the case. You should be reading at least 30 volts at a high idle rpm. If you are, then the regulator is bad. If you are not reading at least 30 volts, your stator is bad and must be replaced.

How to test the voltage regulator


To test the voltage regulator, first you must have a FULLY charged battery in the bike. You'll need a good DVOM (digital volt ohm meter). Connect the DVOM across the battery, red lead to the positive post, black lead to the negative post. Put the meter's function switch in DC VOLTS, 20 VOLT range. Start the engine and bring it to a high idle. You should read 14.5 to 15.0 volts within a few seconds of starting the engine.

To check the output of the alternator, put your meter's function switch in AC VOLTS, 50 VOLT range. Follow the two wires that come from the regulator down to where they connect to the alternator either at the engine case or a plug. Disconnect the plug and look inside. You'll see two metal contacts in the alternator side of the plug. Here's where you're going to check for voltage. Start the engine, bring it to a high idle, and insert one meter lead into each contact. Since you're measuring AC voltage, it makes no difference which lead goes where. You should read at least 25 volts on a Sportster and 30 volts on a Big Twin.

If your alternator checks good but at the battery the voltage checks low. Replace the regulator.

Good Luck

Test the output voltage. With a fully charged battery, connect a digital volt ohm meter across the battery. Red meter lead to positive and black meter lead to the negative post. Put the function selector switch in DC VOLTS, 20 VOLT range or there about. Start the engine and bring it to a high idle. The meter shoud read out a voltage and start to climb. If the battery is fully charged, it will settle down in just a short while. It should read between 14.5 and 15.0 volts. If it's higher than this, the regulator should be changed.

Good luck

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.

What would cause the battery to heat up so hot that it would boil


Failed voltage regulator could do it too. If you can start the bike, put a voltmeter on the battery or charging system output. Should be around 14-15 at 3000 rpm. If it is much over that your voltage regulator is probably bad. Sometimes those regulators overcharge when they heat up too, if yours is in a location that does not get much airflow it may be possible to relocate it somewhere more "in the wind".
