What kind of electrical system does a Sportster use?
The Sportster Charging System consists of the Alternator (Stator & Rotor), Regulator & Battery. The Alternator is of the Permanent Magnet type, the Regulator is a combination rectifier, shunt voltage regulator & the battery is typically of the Absorbent Glass Mat type.
What should battery voltage be on Harley Davidson Sportster?
Attach the red probe of your multimeter to battery positive and the black probe to negative. Set your multimeter to the DC volts position. The voltage reading should be 12.2 volts or higher. This test only checks the battery’s charge level; it does not check the battery’s ability to supply current during engine cranking.
Where are the ground wires on a Harley Davidson Sportster?
There is one main ground wire routed from the battery’s negative (black) terminal to a stud on the primary case. This is the largest of the ground wires on the Sportster. Start with the larger ground wires first, as they will have the greatest impact on your electrical system if a failure occurred.
What is the voltage regulator on a bike?
The Voltage Regulator is a series regulator with shunt control. The circuit combines the functions of rectifying AC voltage from the Stator into usable DC voltage and regulating that DC voltage to charge the battery & operate the electrical components on the bike.

How to check electrical resistance on Harley Davidson Sportster?
You can measure the switches resistance as well. Set your multimeter to read ohms and place each lead on both sides of the switch. With the switch pressed, you should have near zero ohms present. To prevent the engine from starting with the motorcycle in gear, a neutral safety switch is used.
Are there any problems with the battery on a Sportster?
All Sportster models occasionally have trouble with the battery cables but it seems to be even more prevalent on the rubber-mounted engine models from 2004-up (since the motor moves more in relation to the frame).
Why is my Harley Davidson Sportster not starting?
Place your Sportster in second or third gear for the best results. A battery that can’t start your engine may no longer be recharging properly because of its age and current state of charge. The ground cables that connect the battery to your Sportster frame must also be undamaged and free of corrosion.
What should the electrical reading be on a Harley Davidson Sportster?
A normal reading is between 140 to 180 amps. A lower reading indicates a low battery charge or a starter with a internal electrical problem. A higher reading indicates a mechanical problem with the engine, starter, or high resistance in the starter to battery wiring/starter ground wire.
How does the starter solenoid connect to the battery?
The electromagnetic force of the solenoid switch sucks the movable iron core in the Starter Solenoid to contact the two terminals, one of which connect to the positive pole of the battery and the other terminal to the starter. A ).
What’s the connection between battery, alternator and starter?
The only wires ran were positive + red in my case 4 gauge wires between battery, solenoid and alternator and a black – negative to chassis ground. Click to expand… In an early OEM wiring harness, the very heavy wire from battery + terminal to solenoid is green. Sounds like you have a red one instead…
Where are the starter bolts on a Harley Davidson?
Remove all wiring connections from the starter solenoid and starter motor, using a combination wrench. Unscrew the starter mounting bolts using a socket wrench. The bolts are from the right side of the engine on most Harley-Davidson models; however, Sportster models locate the bolts within the primary chaincase on the left side of engine.
A normal reading is between 140 to 180 amps. A lower reading indicates a low battery charge or a starter with a internal electrical problem. A higher reading indicates a mechanical problem with the engine, starter, or high resistance in the starter to battery wiring/starter ground wire.
How does the electrical system work on a Sportster?
Over the years, HD has grounded the Sportster electrical systems in a number of ways. In the early models (typically, 1993-earlier), components were grounded to the frame at a nearby point while power was distributed throughout the system on a minimal number of wires in the wiring harness.
How does a starter solenoid work on a Harley Davidson?
Connect one end of both wires to a fully-charged 12-volt battery’s negative terminal. Connect one of the free clips to the starter solenoid’s field coil terminal, located on the right side of the terminal. Connect the remaining clip to the starter solenoid housing to serve as a ground connection.
