Best answer
Check the voltage coming off the main post on your alternator if it is below 12.7v , disconnect the terminal on the main post and see if there is output from the post. You may have a wiring issue, or a fuse was blown and never replaced whenever you replaced your generator. Check your generator fuse and or generator relay. This can also sometimes be a ecm fault.
