Either way I would check the battery electrical connections, battery and alternator voltage and the ground strap.
Sounds like you need a larger alternator, no enough amps for the load
I would look for a battery cable issue such as corrosion or hidden corrosion. Also the grounds need to be checked and cleaned. I have had battery connections that looked perfect, but caused issues.
