Hey Guys,
Having an issue with my 2003 (stock motor) voltage dropping to 12.5v when my fan turns on . Only upgrades done were a Ricks motorsport Hot shot stator and rectifier, rebuilt starter motor and 1 gauge wiring from the starter. After I smoked the rectifier by applying 40 amps I decided to upgrade my charging system using Ricks Motorsport Hot shot Stator and Rectifier.
The stator and rectifier checked out fine using Ricks youtube stator and rectifier trouble shooting tutorial. The battery voltage (new battery plus 175 amp batt) measured 13.8 to 13.5 when at idle and 14.7 cranked @ 5000rpm. However, the voltage drops to 12.8 to 12.5 when the cooling fan turns on. When the cooling fan turns off the voltage climbs back to 13.2 to 13.5 before the fans turn back on dropping the voltage. Cooling system seems to be working correctly, fan kicks in when temp gauge hits half way mark. From my observation it appears this cheap #%$ Battery Plus Battery is part of the problem. For example, while charging on a tender the multi meter displayed 14.2v and when disconnected displayed 13.8v within a hour it dropped to 12.98.
This can create a future oroblem when riding in slow stand still tracking and need to cut the bike off. Also, during my test the headlight (all accesorries) were turned off.
Has anyone experienced anything similar with voltage dropping when the cooling fan turns on.
