this is my first time posting on the site but I read lots of posts and find everyone super helpful. Anyways, I need some help with my V6 Raider because I'm stuck.
After noticing slow blinkers, sometimes pausing, and a few days sitting my truck wouldnt start. Started it with a jump, drove it about 1 mile and the volt gauge dropped to zero. The battery was old so I replaced it and after about 3 days the volt gauge dropped again. This made me think that my alternator wasn't charging so I had it tested at the shop and they said its fine... Put it back in, changed the 100amp fuse for the alternator, checked connections, and cleaned up battery terminals and jumped it to life again. After fully charging to 16V, when I disconnected the cables it died in under 15 seconds.

My next move is replacing the alternator.

Any other suggestions?

thanks
