Flickering/Dimming Lights
you forgot, does it do that running engine or not.?
ok the main battery is car is doing that.
use a voltmeter, at the battery or even at the CIG lighter port.
12.6v DC, not running. rested. running voltage is 13.3v to 15vdc,
start engine, is rpm above 800 RPM at all times, or more?
if not, the alternator will be too slow, and drop out and when that happens , the lamps will dim. (a 3 volt drop does that)
1: all fuses good
2: battery term lugs clean, not green
3: fan belt to alternator not loose. slipping.
4: charge lamp on dash not ON, running.
5: check engine lamp not on, running (if yes,scan it now)
6: test the battery , batteries are LOW life objects, (die-easy-not-hard)
test the battery , using a load tester or take it in for testing, it's free.
or try a spare battery from another car. do not reverse POLARITY.
this gets the lions share.
hey ram,fuse and batt were 1st thing we checked.drove it autozone and hooked his diagnostic machine and obd to it and said everything was ok.he suggested next time it acted up to run a wire from neg on batt to a ground on engine. checked the grounds from batt no issue.when i took it out for test drive last night now i get a batt light at 2500rpm along with the dimming lights.all signs point to alt! are the autozone diagnostic machines reliable?should i remove alt and have it bench tested? thanx rich
