'05 Ford Excursion 6.8L V10 3G alternator adaptation

[Randy]

From an email...

I own a 2005 ford excursion 6.8L V10 Gas.  Will the F1-3G-A200 or F1-3G-HD200 work on this vehicle?

[Randy]

My answer...

No the 3G is not for your vehicle. My application guide says your 2005 Excursion with the v-10 motor came standard with the 110 amp small case 6G series alternator. The good news is that we have a direct fit 6G in the large case that fits your Excursion. The large case produces more power at idle and it's larger mass absorbs  and dissipates more heat so the large case works better than the small case at higher amperages. The heavy duty version is best as it has higher amperage rated diodes, copper heat sink and a larger battery post that is silver soldered to the positive rectifier, the stock stud is smaller and just pressed into the heat sink. 
 
Thank you,
