Start at battery and check for clean grounds. Voltage drop testing is what we use for this. I use a power prob that connects at battery and has volt gauge and can have power or ground with push of a button.
Just replaced the battery. Cleaned all cables still no change.
Having similar problem as well as dash lights going black. Was told to replace the headlight control switch.
