ok so i been having a on going issue with my altanator my battery light keeps flashing and diming on and off power to all stuff starts failing like the altanator is dieing so i go and have my altnator tested twice at auto zone and it passes i even clean the terminals and snug up the female conecters on the green plug that helped and when i play with the plug it starts working then when i drive it comes back on at high rpms anywhere from mid 4000 to 5000 it goes off then poop back on anyone ever had this issue i tired of that god forsaken battery light and my lights diming i just wanna make shure its the altanator before i throw money at it

 

have YOU put a volt meter on the battery while its dieing down?

 

no it will only die down under constant load like 60 mph with lights on blower fan on etc i cant get it to show signs at idle or reving it will just twiter with the altnator cutin on and off

 

It sounds like a bad ground.

 

i have new ground wire 1 from the battery to the frame and frame to trans like it was from the factory and 1 off the vale cover its been fine all this time up to this point i have a feeling its the plug on the altnator end and not the green plug all my factory wiring is in tact nothing is hacked up just a couple of re pins for the swap nothing is half assed so i dont see how it can be a bad ground and when it dies it goes really slow not just cut power like when a altanator normally dies but if i pull over while the battery light is on and play with the plug u hear it ajust idle and the altnator start charging
