Posted before about my 2006 Sport having a batt light on. Checked batt, showed 11.6, replaced. Light still on, checked alt, 12 9 running....replaced alt.Now batt at 12.8, running , alt is 14.2, drops to 13.9, 14.1.....light still on . Alt harness is mint, every fuse has been checked, all the 7.5 replaced....scanned, clear...one member here mentioned that it might be a bad diode? Is there a diode that can trip the light (no 12v output for light) and will still let the alt charge normal? I'll replace the Remy rebuilt alt if there's a chance that a bad diode could cause this.....figure that someone on the site does electrical trouble shooting...Thanks, rsbhunter
