If a 01 sportster is getting no spark is it the voltage regulator.Has a new battery and plugs?

The voltage regulator is part of the charging system. u have a problem with ur ignition system If u have a no spark condition then check the following; Plug wires,Coils, Wiring from ignition module to coils,wiring from the main switch to the ignition module and the wiring to the trigger sensors u have a new batt just make sure it has a full charge with electronic ignitions never crank the engine over w/o grounding at least one of ur plug wires otherwise u can damage the ignition module
