Battery warning light 2001 LC 100

[Natal]

i just replaced my OEM alternator . for a high amp output alternator. now battery warning light came on . I'm getting a solid 14 volts and my battery is holding a charge. dose anyone if the 3 wire connector that gets plugged in to the alternator have anything to do with the battery warning light?

Hey Star, thanks.

It also handles excitation and importantly the battery sense wire. There is IIRC a chart of all the pinouts on Google that can be used to check that what you’ve removed corresponds to what you’ve fitted.

Have a google with the model number and make of your new one to cross check.

Good day. thanks for the information its pretty much what i needed. to trouble shoot. if its not a loose connection or something of that nature i will put the oem alternator back in and see if it goes out if it does ill send the high amp alternator to have it checked. thank you. StarCuiser
