Lights dimming while at idle especially with turn signals applied.

[Broncoboy36081]

Well the title says it all. When I'm at a stop light with my turn signal applied I notice the headlight and dash lights will dim ever so slightly. Battery, stator, or rectifier? How to trouble shoot. All I have done is check the grounds. All seems well. Thanks:depressed:

Most likely it is nothing to worry about, the stator can not put out enough power to keep everything going when at idle.

Simple test. check the voltage across the battery at idle with everything turned on, then bring the engine up to around 2500 or more RPM and if the voltage comes up to around 14V then all is as it should be.
