Figures....all of a sudden my daughter leaves and calls with this? Of course it's like 20 degrees outside too! New Remy alt. 3 mos. ago and I checked battery cables for tightness? PO replaced battery..I think like 3 yrs ago but it did peter out a couple weeks back when I left the ignition key in for 3-4 hrs.?? I charged it up and no problem, though I'm not surea bad battery could/would even produce these types of symptoms anyways.....will further investigate in the a.m. Well, she'll(daughter) really learn to appreciate the TB after driving the S10! lol!

I had rapid flickering and voltage gauge fluctuations on my TB a while back. The shop tested the Alt, Batt, Etc and everything checked out ok. On a hunch i bought a new alternator and cured my problems. So if you get it tested and even if their little machines say everything ok. my past experiences pointed directly at the alternator.

if I recall correctly a fault ignition can cause all kinds of strange symptoms

Thanks everyone. I drove it to Advanceauto and the gauge was all over but of course it seemed to straighten out once warmed up and there.....It all checked OK so I think at this point I will just go ahead and get another new alternator this week.always something............................

Wheres Roadie when you need him.....If its the problem i think it is,,its not really a problem.....It has something to do with a cold start and driving off before the system has a chance to do a quick check/ letting it "warm up".....If i hop in my voy and drive off quick i will notice my headlights and voltage gauge dip 3 or 4 times...its not a issue.

The 2002 and 2003 don't have that secondary air pump.

Also, that only lasts 15-20 seconds.

yea and this lasted 15-20 min. of driving. The freaky thing is how it tempers back down once it warms up though I have only driven it once and my daughter 1st noticed it just last night due to the lights flickering(so she describes?) Well hopefully a new alternator will remedy. I was busy today and must admit, I haven't checked the other side of the ground that connects to block or maybe alternator bracket? Time will tell...

there is a ground cluster on the passenger side of the truck by the tranny tunnel inside the truck, that may be loose, these were some symptoms that i had and then BAM my key would couldnt out of ignition, its always a good thing to check as a just if thing.

Thanks, good to know, anybody got any pics of this ground setup? I did trace ground to block which seems tight to the eye....and threw another Remy alt.on so we should know pretty soon if it's resolved. just seemed like a messed up regulator to me, it had a goldish pulley and ribbed yellowish center(between case halves) the newest was black pulley with black/smooth center with a made in mexico sticker. Two different suppliers????same box.
