... just make sure the op amp output turns ON at around 12 V. You can put an LED/1k across pin6 and ground to confirm the results. 2. I just measured the amp draw on my 04 SG to see if it could handle heated riding gear. The motorcycle battery's primary job is to start the bike and to supply any extra current the bike requires when the alternator output is lower than the current draw. 5. It is equally important that the system is neither under- … When The Output is Low This normally only happens at low rpm, when electrical demand is high and alternator output low, as it might be when stuck in slow traffic or cruising at low speed. Permanent magnet shunt regulated alternators output full power at all times. The current dropped off to 8.3 amps as the fuel pump warmed up. They are usually designated by amperage out put such as a 22- amp or a 32-amp system. ... high output motorcycle alternator for victory, motorcycle alternator output, motorcycle stator voltage output, on a victory cross country motor cycle where is the alternater, Js Alternators began building high output alternators in 2013. It is important that the alternator is capable of delivering the correct voltage and current output. Start and rev the engine to 3,000 rpm. The regulator part of the regulator-rectifier is used to regulate the output-voltage (to the battery) to the 14.4 Vdc that is needed. Diagnosing Alternator Charging System Problems Over the years Harley Davidson has used many different alternator systems. Accounting for other power needed and losses, your stereo might draw a couple of amps. Generally, you can check motorcycle alternator stators while they're installed on the bike, using a quality multimeter. The output voltage should be set at 14.5v to properly charge the battery, however the load also changes if the battery is charged or discharged, turning on and off the headlight would also change the load. The tests will help you to identify or eliminate the stator as the problem in a charging issue. If an analog meter’s needle swings backward, that's good. In other words, 3 amps in the case of a 12 A/H battery. On a digital meter, you want a "–" (negative) sign. Don't forget that there is a 40 amp circuit breaker immediately after the positive battery terminal. Since the regulator-rectifier cannot be … Contact Us. With the headlight on high beam and the engine at 3000 rpm the drain on the battery was 9.2 amps with the alternator and regulator disconnected. Until recently the easiest way to tell the systems apart is by looking at the plugs that connect the stator to the regulator. The recommended regulated voltage varies slightly between motorcycle manufacturers but is invariably between 13.5 and 15.0 volts. 116 a Ridge Road, Greenville, SC 29607. Connect with us. 4. We deliver nothing but outstanding reliability to our customers. Your amp power is probably peak to peak power, so true RMS power is more like 7 watts/channel. Reply. Our units range from 240 to 390+ amps, each one created custom! It should say in the specifications. If forward, reverse the connections. The result should be at least one-fourth the battery's amp/hour rating. High amp alternators, high output alternators and high performance starters ranging from Automotive (Foreign and Domestic), Agriculture, Marine, Motorcycle, Recreational Vehicles and Lawn and Garden. A motorcycle voltage regulator should keep the voltage within 13.5v and 14.5v at any given engine RPM. 3.
