Alternator
I have an 84 GMC Truck. My alternator does not appear to be charging the battery. It is not making any noise. Is their a way to check an alternator to see if it charges????????????????????

take it down to your local kragen (or checker, schucks or whatever ya got) and they'll bench test it for free. if the truck's running pretty reliably drive the whole thing down and they'll test your whole charging system to see if 1) the alternator is working right, and 2) what charge is getting back to your battery. that way you'll know if you might have a problem somewhere else in your system.

You could just disconnect the neg batt cable while it's running, if it dies, it's not charging!

No offense, but the batt is disconnected, you can start the car, throw the batt in the garbage, and if the alt is charging, you can drive all day!

check the voltage at the batt. <=12.6 no alt >12.6 good alt
dissconect your batt with engine running for a long time and fry things . try it and check voltage at alt. no 12v sense for regulator and alt. voltage goes sky high.

I did get a little carried away, but , my point was, batt state of charge has nothing to do with how long it would run disconnected! Hope he's not drivin w/o it?

Thanks guys I traced it to a burnt connection on the positive connection. I replaced the bolt with a regular bolt that was black and when I fired it up the gauge goes to like 8 volts and I wants to die as I have an electronic choke. Can I use a regular brass bolt or do I need the actual bolt?
ps..how are the springs supposed to go in and are they supposed to touch against the shaft?

Not sure which bolt you're workin with? Alt b+ bolt?, you may want to check all the other components inside if you had a burnt connection, or replace the alt? The springs go in behind the brushes, and are held in with a paper clip type wire, thru the back of the housing, pull the wire out after assembly! HTH

Done deal. Thanks Guys. I replaced the positive terminal and put in a new set off brushes and the back bearing. She runs great again. Thanks for the time and knowledge.
