Lights flicker...voltmeter-up and down. HELP!
Ok guys, I need help......yes I have read every thread on the flicker/voltmeter problem, but it seems when people get it fixed...they don't post.
Problem.....driving on the highway lights (dash/or headlights-headlights do not have to be on) will flicker quickly...voltmeter ticks in unison with the flash. Sometimes.....voltmeter will slowly drop to 10, then back up to 14 (65 mph).
Truck at idle or driving (normally) is a constant 14...turning anything electrical on does NOT bring the voltmeter down...always 14.
And...it doesn't always happen...I could drive 2 or 3 days...fine.....4th day, it happens.????????
What are the symptoms of the headlight switch????, but again...the headlights do not have to be on for this to happen......Relay??????
If it's the alternator, fine I will replace.....I just don't think so.....volts are always at 14 or slightly above...no matter what I turn on.
new positive battery cable end
cable end at alternator new
new negative batter bolt
all terminals cleaned
new starter about 6 mos. ago
new fusible link (wire)
1997 s-10 2.2 auto, air (not hooked up) 190k
Thanks for your help!!!!!!!!
