High Voltage - Hemi Alternator Overcharging Problem Fix by DIYHEMI 

Have a late model hemi swap or modern Mopar with an overcharging condition?? This could be your fix! A lot of people think it's the alternator but it could usually be a problem more in depth than that.
With many Hemi swap applications, the over charging/ high voltage problem can be due to not having the proper sensor for the inlet air temperature reading. This particular case, did not have that sensor and we needed to bypass it using HP Tuners and reprogramming the ECM PCM. We hope this helps you other guys! If you have some time, please help us out by checking out or website and store!
Thanks guys for watching
If you want to help support us more! Please check out what hemi parts we have available in our store! We are continuing to add products to our hemi swap product list. Our new QUICKHEMI harness is now in stock for a full plug and play standalone harness that plugs into the factory PCM/ECM and the existing engine harness. Yes our harness saves you a good bit of money because we still utilize the existing engine harness that will usually come with your junkyard swap hemi.
