2008-1098, I recently replaced a faulty voltage regulator, so not if this caused the problem. Started fine and was fine for that day afterwards, didn't get a chance to ride since. Now when I go to start the bike it will not even try to crank over. Turn key, press starter button, followed by a sound of maybe a relay, will not crank. Voltage is 13-14, and is on a trickle charger. Any recommendations to narrow down the problem?
