    Hello, I have a problem to where I randomly get charging voltage coming off the alternator to the battery,

    Following Problems

    Charging system warning light active on Dash, AFC shows randomly , per each vehicle startup, that the battery will be recieving a charge. ex 14v.

    Taken The following actions.
    Replaced Battery
    Tested Alternator

    Cannot see it being the connections, and it appears to be the generator relay. would anyone have a pic or be able to describe to me where it is, thx

    Also, I just noticed as well, dash lights are showing low coolant light on along with winhshield washer light ?? , temp is ok and full of coolant and winshield fluid, just the lights are on for some reason ,, huu?

    The generator relay should be right next to your coolant reservoir and kind of under your air box. It's the only relay there so you shouldn't have much problem finding it.
    (All of this being on the passenger side of the engine bay).

    I just found this out today myself thanks to the handy service manual. My relay just fell apart putting my engine in and so I've been searching for what it was but now we both know.

    I do realize this is a old thread, I have now replaced the alternator after much cussing, and problem resolved, charging system warning light gone, and now charging correctly, This is ment for reference for anyone else w/ issue like this,,

    Heres a pic, came across this thread trying to figure out my charging issue, the brake and coolant lights would come on and it would stop charging, but when it was charging (randomly) it was going great.. found this guy after seeing this thread and it fell apart really easy and was loose when i took it off.. anyone know where to find these guys or what to ask for? I went around town asking for an alternator/generator relay and no goof at the computer could find one.. really dont want to go to the dealership if I dont have to.

    Yes there's is a post with an autozone part #. May cause charge/battery light to come on I think the alternator may still charge battery tho idk mine juat fell out like that too and I thought it was broke but nope looks like a plastic salt lick(mini size) w/ a resistor and a 4 pin connector but the 4th pin is pushed in and not used on mine its upside the white rectangle just like his pic.
