No I cant wait, and I decided to just go with a set of Motor Craft Batteries, I figured that with a good alt. and updated wiring it should be good enough and the warranty was better.

New parts are seduled to go in tomorrow.

As for the battery voltage 12.7 sounds good with the truck off, check it with the truck running and all acc. off should be around 13.5 or so.

Great. I checked voltage today before starting for the first time, and it was like 12.44. Fired her up, and it quickly went up to 13.88.

I think it's safe to say I'm in the clear now. I still do plan on getting that DC alternator, so when this one does take a crap I got a badass one on hand. I need new tires and shocks before I do that though.
But anyways, thanks for all of y'alls help, I appreciate it.

Amazing, not one person talked about how each vehicle today needs to have the right voltage regulator in it to work right to start with.

If you're putting the wrong one on, your asking for trouble. One reason they have gray, black, white, etc. along with the brush holder colors to let you know what to use. The ECM expects to see voltage and wave output at set points. It it does not it causes sensors to go out or fail prematurely.

You might keep that in mind when you buy one. One reason parts houses fail, cause they never checked to see if it had the one.

That statement right there says it all, no one takes pride in there work and the rebuilders are terrible, and they use the worst quality parts possible to keep the cost down.

I been doing charging/electrical systems so long, I forget not everybody has the time to research and understand them.

its a system built around the alternator, wiring, fuses, battery, grounding, etc. and it all has to be safely installed.

I built one for my personal use conversion van. Parts used xantrex converter 2500 watts, custom built alternator, wiring, fuses, charge controller, northstar AGM batteries with 190 rc@25 amps, not your everyday installed electrical system.

I might add the cost is not much more, maybe $100.00 for quality parts. One reason I don't use optima batteries, Northstar are the same price and last forever.

The junk yard is full of factory parts as well, for pennies on the dollar. Something people over look.

Again,

Like I said for the big chain stores, they are not using high quality parts that a place like DC Power uses. You cant even buy a NEW alternator from a dealer anymore. Its all reman, and unfortunately people dont want to pay for someone to rebuild there current alternator with quality parts becuase it would be 2xs the cost of a reman unit with a warranty.

I own/operate a repair shop and have done my fair share of warranting parts because of quality issues. If I could build a system for every customer that comes through the door they would never have issues again, but I wouldnt make any money either.

I never had any problems with customers after I explain to them the reason for paying a little more.

Number one, it will be dependable and last.
Second, I don't like come backs, it cost me time and money, and third, I want them to be happy and spread the word this guy delivers quality service, and it works. You can't buy that in any chain store.

There have been a couple DC failures in the last year or so.

Biggest thing for them is customer service sadly

I don't doubt it. half the people I installed them on cant tell me why they need a 250 amps alternator, when they only pull maybe 90 amps at full load. The alternator never even gets off idle output in its life time of use.

Then you add in wiring, fuses, batteries and upgraded solenoid, it gets expensive. sometimes it cost more then the alternator its self.

I did my brother inlaws power stoke using a Snap-On hand held. Cold start injectors pulled 50 amps for 11 seconds from the battery. The alternator can put out 95 amps at idle. The whole system with everything on pulls 105 amps, that includes a inverter for the horse trailer/sleeper he pulls.

He never has everything on at once when he starts it. so he would never use more then 60% of the rated output. Which is how an alternator should work, it last longer, stays cooler and is more efficient.

Agree. I ordered my 185Amp over 4 weeks ago. They have yet to ship it to me. I have called so many times I have their number memorized. They finally responded to an email and stated they are getting parts in and will ship in two days. My truck has been down for a month...I must say that it is pretty frustrating to wait this long for a part when they charged my credit card within a few days of the order being placed...

Any advice??? Continue to be patient??
