Dual Alternators
Does anyone have the dual alternator option? What are the pro's and con's? I ordered it but figured maybe there was more I should know. Is it just more stuff to break? Are they covered under the 100,000 mile warranty? Is one alternator not enough?
Thanks

Yes, you can charge a trailer battery--if you have the 7 pole connector on the EXC, it has a charge line that will mate to the trailer connector. It will charge while you are driving. BUT, there isn't much left on the alternator while running stereo and a/c--if the battery is low, you will need to drive a long way. Basically, it will keep a well-charged battery up--it won't do much for one that is dead.

tblueV10………thanks
Now how do I do it? Yes I do have the large connector by the hitch, had a 01 v-10 and it did not have the small four pin, 1 male 3 female, like my 03 does but everything else is the same. It came wired for trailer brake plug in under the dash.
I do not need to charge the bat just keep it charged.

Is the dual alternator option aimed at any specific use(dual batteries?) or does it just charge better?

The 2 alt. do not charge the batteries individually. The batteries are connected with a regular cable and no isolator so there is no way they are on separate circuits. I would imagine that you could unplug on of them and not see the difference in charging.
For the trailer Batt. look on the cover of your trailer connector. You should see a wire that says AUX. Run the truck and check it with a test light. It should be the hot wire. I use this to charge the battery for the winch on my car trailer.
