charging problems

[jamesp4]

Went to have work done on my truck and they said they KILLED the batteries and did not charge them up all the way. 2 days later my altenator went out. Put in a new altenator and now 5 days later the battery light is on and it looks like the altenator is not charging again. Can the low batteries cause the altenator to burn out.

yes,low batts can kill an alternator.how old are your batteries?1 dead one can also kill the alternator as the junk batt will bring the good batt down and the alternator is trying to charge both even though the junk 1 wont charge

I think I have found the problem. Before I left work I started moving wires around buy the under hood fuse block and the altenator and when I started my truck it was charging again. Now I have to track down the loose wire. Tahnks agian for the help!!

You may want to check the fuseable link, sometimes it gets hot, but not to the point of breaking the link, causing a higher resistace with intermittant connection properties...
In other words "Just plain flaky"

Good luck!

check the little 1 wire plug going into the alternator.i had an issue on my 94 that when i was messing around near the alternator it wouldnt charge or the battery light would flicker for a few days.i replaced the plug and havent had an issue since

Thanks I will try that. By the why where would that fusable link be?
