SOURCE: while riding all lights started to flash engine run erratic bike died of death bike will not start

Start with charging and load testing the battery. Then test the stator, to test the stator on the bottom of the right down tube is the plug that goes from the stator to the voltage regulator. With a multi meter, read the voltage from the stator, I forget the exact values but as you rev the motor the voltage should climb if it dosn't your stator is bad. If the stator is good take a reading again with the motor running at the battery cables, again I forget the exact value but you should have a steady reading at the battery, if it isn't and fluctuates it is bad.

SOURCE: Harley 03 Ultra overcharging, 16 volts

14v is not overcharging. 16v is pushing it. I'm with the regulator opinion, but I would also load test your battery. If the charging system thinks your battery is low it will try to compensate by putting out max voltage, putting additional strain on the regulator, which in turn overcharges the battery... creates a vicious cycle. Is the regulator in a spot where it gets quite warm? They have a tendency to overcharge when hot. If that is the case, try relocating it or directing more airflow over it.

Turn the Bike on and the Radio off and then follow the buttons on the screen. Most people think you have to do it while it is running and this does not work

SOURCE: oil blowing out through air-filter,rough

Your '98 Evo motor is what they call a "head breater" engine. This means that the crankcase ventilation is at the upper end of the heads rather than way down at the lower end of the engine like it used to be. They the first year for the "head breaters" was 1994.

Now, At the top of the heads where the rocker boxes are, there are three pieces. The lower rocker plate with the rocker arms in it, the middle piece and the upper cover. If you take the four bolts out, you'll see an umbrella valve in the middle piece of the rocker boxes. This valve is a replacable rubber piece. Over time and many times of heating up and cooling down, they can get brittle and allow a lot of blowby resulting in oil in your air filter element.

Now there is another part in the cam chest that has a lot of effect on the operation of the crankcase breather system on your bike. This part is called the "breather gear" and is located down in the cam chest to the rear of the camshaft. In you bike, the part is made of plastic if it's the original part. I have seen the teeth break off of the drive gear and the breather gear stop turning. This will screw up the "breathing cycle" on your engine and cause it to "blow oil". Usually, the oil pump locks up when this happens due to the plastic teeth getting in the oil pump but not always. If this eventually turns out to be your problem, have the mechanic or yourself install one of the new S&S reed valve type breather gear replacements. They don't turn at all and work absolutely great. The part is about a hundred dollars but it's well worth it. Solves the old broken breather gear problem that has plauged the Evo engine it's entire life.

There are no "screens" in the Evo engine other than the "tappet oil screen". Just in front of the oil pump is a screw plug that is in the engine cases itself. If you remove this plug, there is a small spring and cone shaped screen that filters the oil prior to it going to your tappets. This should be cleaned every other oil change but it has nothing to do with the oil in your breather.

Now some riders will tell you that if you allow your Harley to sit for any length of time that it will "oil sump" with you. By this, they mean that oil will seep past the check ball in your oil pump and pool up in your crankcase. When you start the engine up, oil will be blown into your oil filter. Not true on your Ultra. The bikes that will oil sump are the Sportsters, Softails, Shovelheads, or any bike that the oil tank is higher than the oil pump on the frame. On your Ultra, the oil tank is on the bottom of the transmission. Your bike will not "oil sump" unless you have a sheared key in your oil pump or the oil has somehow learned how climb. You oil tank is below your pump in other words and oil does not flow uphill.

sounds like your voltage regulator has gone bad, voltage spikes like that can damage a lot of the electronics on the bike. Would not operate it until you fix the issue.

Hi, i wash my bike after along ride and what happen i get a electric problem, the batery voltage go down to 11.5 when i push the front or the rear break, i chek all the whire and i did not found any damage...


Now, you didn't say whether this was with the bike running or not. If it was NOT running, I wouldn't worry too much about it. But, if that's the voltage with the bike running, you may have a problem. The first thing I'd do is let the bike dry out completely. Then, check the plug where the voltage regulator plugs into the engine cases.

To check the entire charging system, make sure that you have a fully charged battery in the bike. Put a charger on it and charge overnight. Then you'll need a DVOM (Digital Volt Ohm Meter). Connect the meter across the battery by connecting the red lead to the positive post of the battery and the negative lead to the negative post of the battery. Put the meter's function switch in DC VOLTS, 20 VOLT range or higher. Start the engine and bring it to a high idle. After about thirty seconds or so, the meter should read 14.5-15.0 volts. If it doesn't, you have charging problems and you need to check the alternator.

To check the alternator, unplug the voltage regulator at the front of the engine cases. Insert one meter lead into each of the connector sockets in the engine side of the connector. Put the meter's function switch in AC VOLTS, 50 VOLT range or higher. Start the engine and bring it to a high idle. Don't allow the test probes to touch the engine case. It's actually better to start the engine first and then insert the test leads. You should read 30 volt AC or better.

Now, if you don't read the 30 volts out of your alternator, your stator is probably bad. If the alternator test reads correctly but the entire system test reads low, your regulator is probably bad. If everything reads correctly, everything is working as it should. If your rear lights are drawing too much current, they'll trip a breaker or blow a fuse.

Good Luck

Engine light on running rough speedometor behaving errecticaly then speedometer pegged at 0


I had a similar issue on a Sportster, the battery cable had broken due to engine vibration, you could not see that it was broken as it had broken right at the cable end and was still making enough connection to start and run the bike, it would act erratically when riding, the tach and speedometer would either flutter or drop to 0. I didn't find it until it eventually failed completely.

Ok, let's check the charging system. The battery is easy. Take the battery out of the bike and take it to an automotive parts store. Ask them to load test the battery for you. If the battery is over two years old, it could need replacing.

Once you're sure the battery is good and it is FULLY CHARGED, we can test the rest of the system. You'll need a DVOM (digital volt ohm meter) to check the system. With the battery back in the bike, connect the DVOM across the battery. Red meter lead to the positive terminal of the battery, black meter lead to the negative. Put the meter's function selector switch in DC VOLTS, 20 VOLTS or greater. Start the bike and bring it to a high idle. The meter should read 14.5 - 15.0 volts.

Now, to test the stator, follow the wires from your regulator down to where it goes into the engine cases. Disconnect the connector and look into the engine side of it. You'll see two metal contacts down in there. Set you meter's function selector to AC VOLTS, 50 VOLTS or greater. Start the engine and bring it to a high idle. Touch each one of the metal contacts down in the engine side of the connector with a meter probe. It makes not difference since we're measuring AC voltage at this point. The meter should read at least 30 volts.

Now, if the alternator (stator test) does not put out at least thirty volts, the stator is bad and needs to be replaced. If the alternator does check good but not enough voltage at the battery, your regulator may be the culprit. Make sure all connections are clean and tight and that the body of the regulator is grounded good. Recheck the test at the battery. If it still fails, replace the regulator.

Now, I've seen may problems such as your's that are intermittant. In other words, the problem is here on minute and gone the next. I fought that on one bike for over a year until we finally replaced the entire charging system and fixed it. If your bike proves to be doing that, you may wish to consider that option. Fix the thing and be done with it. I wouldn't buy the rotor, just the stator and the regulator.

Good Luck

Let's start by taking the battery out and taking it to an automotive part store. Ask them to load test the battery for you. They'll usually do this for no charge. If the battery test good, put it back in the bike and make sure it's charged up fully.

Now, connect a DVOM (digital volt ohm meter) to the battery. Red meter lead to positive, black meter lead to negative. Put the meter function knob on DC Volts, 20 volt or greater range. Start the engine and bring it to a high idle. You should be reading 14.5-14.8 volts across the battery. If not, check the output of your alternator.

Unplug the regulator down at the cases just to the left side of your oil filter. Look down into the connector and you'll see two pins. Put your meter's function knob in AC Volts, 50 volt range. Start the engine and bring it to a high idle. Touch one lead of your meter (either lead) to one pin and the other lead to the other pin. You should be reading thirty volts or more.

If not, you probably need to replace the stator in your alternator, If you read 30 volts or more, replace your regulator.

Now, as to whether or not this will correct your speedo problem, I have absolutely no idea.

Good Luck

Oil pressure


Your Bike is a dry sump system oiling system which simply means that the motor needs to be revved up to get oil to the top of the motor. The readings that you see are actually normal (look closely at the gage and you'll see that you are actually are around 5psi at idle and in the 30psi range while moving). Great Bike!

Engine light on/off sporadically while riding. 2002 Ultra Classic. Fuel hoses in tank just replaced and oil pressure good. Possible oxygen sensor??


You don't have that on a 2002. Do you have a power commander on it? Sounds typical of the older style power commander ( IIIr ) one thing to pay attention to is does it do it under load? If it's not showing any historic codes and the bike rides fine, and you have a power commander 3r I wouldn't worry. It's normal. The older power commander lies to the ecm. Sometimes it gets confused and kind of glitches ( that's where the light comes from ) but if it has running issues to I would take it to a shop to find out what the codes are and go from there.
