Dc Alternator ordered
I Just ordered the 250 amp during the $50 off sale. I've had a 140 amp db,
250 amp tenney and now im using a local 150 amp alternator. I think the glow plugs draw more power than the alternator can supply, it burns out
Hopefully this will be my last Alternator for my Excursion

The DC Power alternator is a better one than what you have had before, but it is not a guarantee that you will have no failures. As others have said, if it does fail, the fact that you have to deal with them over the internet or by phone makes it hard to resolve quickly. I think it is worth it, but I also kept my OEM one as a spare.
It is sad what happened to people with failed Tenney alternators! What issues did you have with the db unit?

The alternator seems to be a very common issue with these Trucks but whats weird to me is Ive had my 2006 6.0 just over 2.5 years & never had an issue, plus my Dad bought his 2004 6.0 about 7 years ago & is still running the same unit also.....Weird 
Whenever mine does die i'll be buying a DC due to popularity on here

Did you have a tenny that died? My local shop took it apart and found the Chinese bearing had failed...

I called Excessive Amperage and talked with Nate. I am going to send it in to them and have him inspect and repair it.

I have those on my list as well (Die Hard platinums), but I want to upgrade the alternator first so that I'm covered all around. I like the looks of the DC 185, but have heard the issues some folks are having if/when the unit does go out (hopefully it never will though).
