I've had our 03 Roadsmith trike now for 2500 miles.I'm starting to hear a whine and also notice the lights get alittle brighter if I rev the engine, and the whine sounds abit higher in pitch. Does anyone know what the standard amps are on a factory alternator are? And where is a good place to buy one,not looking for cheap but something that is long lasting. Thanks in advance for any info,I need all the help I can get !
