alternator

Lights on dash are slow to bootup + "wait to start light doesnt come on anymore which I suspect is a failing ecu. Whats the best place to get it repaired/ order a new one? Also how to I check for alternator noise?

Hello Folks, I haven't posted here in years, thankfully to a reliable truck. My truck (1997 12 valve 4x4 all stock) sat for a couple months and the battery's were almost dead. Turned over a couple times but no fire. I charged them each overnight, took the truck out and after a mile the GEN...

I'm pretty bad at diagnosing. I thought I had a bad alternator, and I replaced it to find it still won't charge, and my gauge on dash (that and fuel gauge are about only working gauges) shows it too. I don't know where to start. Circuits that control my AC blower, some gauges, power windows...

Ok, seems I've got more than my fair share of strange things on my truck... here's a kind of new one that has been getting worse. When the alternator is under high load, say over 90 amps, the truck idles very rough, and appears to be misfiring on at least one cylinder. It goes away as soon as...

Have a 2000 5.9 with 170k. Given the age I’m concerned that pulley bearings are going to fail soon. Given I tow a camper with the vehicle, trying to avoid future roadside issues. Looking to do the work myself but looking for any/all guidance. If anyone has docs/pics to share or can direct me...

My truck didn't start yesterday, the batteries were showing about 9-1/2 volts. I charged it overnight, and today took it to O'Reilly's and they said my alternator was good (it's only about 2 years old and I replaced THAT dead alternator over the same concern, it was just dead one day.) My...

Hey all, I got my new-to-me truck just about two weeks ago. 2005 2500 CTD with 88,000 miles. Last weekend I was driving and everything was fine, then suddenly the "check gauges" light turned on and my voltmeter read 0 volts. The Truck was driving fine so I finished my drive. Hours later I go to...

First, my apologies for bringing up this matter once AGAIN within this forum. The questions that I raise have been discussed multiple times so I will gladly accept re-direction to appropriate threads or guidance from members. I have owned my 1998.5, 24 valve 2500 since May 1998. I ordered it...

I'm trying to rebuild the alternator but the instructions from the rebuild kit (geno's) leave a little to be desired. I'm attempting to separate the front from the back and the instructions say to gently tap them apart. I've been tapping them apart and used some screwdrivers to try to persuade...
