[QUOTE="los33, post: 8602603, member: 660834"] The alternator will charge at 14v if the battery wont hold a charge, the temp system on those fords will lower voltage to 13.3-13.5 once battery is near complete charge. The aluminum bodys usually have lots of paint so sanding is needing for all grounds to the frame. Also if you have a ground loop it is most likely the oem engine grounds that are getting noise, so a simple swap to a better cable with thicker jacket would help. Pretty much a big 3 is needed. You can always clear the static by creating your own 12v switched relay setup that will isolate it from the stock system. Sent from my Moto G4 using Tapatalk [/QUOTE]
