My question was in regards to the DC 185/190 amp alternator and the voltage during GP cycle.

The Visteon 160 amp will do high 12's low 13's during GP cycle. The Prestolite 230 amp is 13.8+ volts.

Seems the 130 3G and 140 6G are low 12's and the 110 amp 6G is 11's

My dc power 270xp is right up at 14.6-14.8 during the gp cycle.

 

Yes indeed, few alternators can keep up with the demands of running the motor in concert with the glow plug cycle. Turning on the heated seats right after start up just exacerbates the issue. When shopping for alternators, it's generally all about what they do at hot idle. In the case of our 6.0's, though, cold idle numbers have bearing as well. Solid voltage = happy FICMs.

Here are some options with current prices *including delivery* that we could hook you guys up with from DC Power:

$309.95 - 185 amp OEM - 100 amps at hot idle, 120 amps at cold idle, 185 amps at rated speed cold, 150 amps at rated speed hot - no cable kit required

$375.70 - 190 amp HD - 120 amps at hot idle, 140 amps at cold idle, 190 amps at rated speed cold, 170 amps at rated speed hot, cable kit recommended

$457.50 - 250 amp HD - 130 amps at hot idle, 165 amps at cold idle, 250 amps at rated speed cold, 200 amps at rated speed hot, cable kit required

$629.95 - 270XP - 180 amps at hot idle, 200 amps at cold idle, 270 amps at rated speed cold, 250 amps at rated speed hot, cable kit required

$899.95 - 370XP - 190 amps at hot idle, 215 amps at cold idle, 370 amps at rated speed cold, 330 amps at rated speed hot, cable kit required

$110 - 1/0 cable kit, custom longer length for the 6.0 to allow routing around things like the CAC tubes. Kit includes 1/0 wire from the back stud of the alternator to supplied ANL fuse block with ANL (imagine that) fuse, another cable from the fuse block to the positive stud of the passenger side battery, and a 3rd cable for grounding from one of the three alternator mounting bolts to the vehicle frame.

What's cool about DC Power is that they also offer a case repackaging service. Essentially, if your current alternator isn't dead, you could just put it on the shelf until the inevitable time comes when you'd be looking to sell the truck.

When that time comes, though, you could just pop the DC Power alternator onto the new vehicle with a different case (if necessary). Of course, there's a charge for this, but far less than for a new alternator...

So...you get to justify a wicked awesome alternator now and keep it forever!

Hope this helps someone out!!
