It's currently loading over 16 volts
I read about cutting one wire that goes thru the bulkhead and run it thru a relay so I did that and the voltage went around 15,5 volt so it's still too high
You probably did the amp meter bypass? I did one a while back but no relay was required.
Do you have a diagram or a description of how you completed it?
Also, the voltage regulator and alternator are the only components that can cause high voltage.
Have you checked your meter with another?
