Hello. Welcome to Just Answer. Please allow me to assist you. If 3 alternators are verified good, it is highly likely that your main fuse cartridge is bad. This would be especially possible if 1) the battery was jumped, 2) the battery was jumped backwards, or 3) the ALT main wire touched a ground whilst being changed. I recommend you check the fuse cartridge. If you are not sure where it is, take a photo of your fuse panel under the hood and upload it here. I will point it out for you.
