On 27 March my battery light came on and the voltage meter began to peg at 18 volts while running, driving or at an idle.
On 30 March, I took the truck too Smart-Mart in <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com[img] /><st1:City w:st=[/img]Tacoma </st1:City> They “rebuilt” the alternator several times but could not get the battery light off or the voltage meter to go below 18 volts. ($120.00)
4 April, I bought a new (not remanufactured) Autolite alternator from Schucks with a life time warranty ($260.00) The light went off and the volt meter read normal for five days or approximately 60 miles.
9 April, the truck failed to start in the AM, making a clicking sound similar to dead batteries.
16 April, had batteries tested both, good to go!
18 April, charged batteries and truck started fine.
19 April, truck failed to start in the AM, dead batteries.
20 April, charged batteries, took truck too Dave’s Auto Repair (Gig Harbor) they stated the alternator was bad ($65.00) Took truck home, returned alternator to Schuck’s and replaced it with a new one.
</O 21 April, truck failed to start in the AM, dead batteries.
21 April, charged batteries, back too Dave’s. they again stated alternator was bad!
22 April, took alternator from Dave’s Shop and returned it. Schuck’s gave a third new alternator and tested it twice prior to me leaving the store, good to go! Dave’s put new alternator in and kept truck over night, started strong the following AM. Took truck home.
26 April, truck failed to start, dead batteries.
27 April, charged batteries, and took truck to Mallon Ford, <st1:City w:st="on">Tacoma</ST1</st1:City>
28 April, Mallon called, truck was dead when they came in at 0700 hrs. I call back at 2PM they say “ we have had two diesel tech’s on the problem from 9AM-2PM, and cannot figure out why your system will not stay charged”
It sounds like you have a short some where. Maybe glowplug relay. Other than a short or something staying energized, bad batteries are the only other thing that come to mind. Keep in mind that our trucks require a lot more juice than most passenger cars and trucks. They have to be very strong to be ok.
And ZX would be dead on most likely. Check the two small wires that come out of the connector all the way to the battery junction box and also the fusible links in the big Black/Orange stripe wire going to the starter solenoid from the alt.
On the fusible links the Shrink wrap should be smooth if it is wrinkled it indicates a blown link.
Ditto, I would look for a big amp drain shorting out. Those new batts and alt ought not fail that quickly. Let's see what the "pros" come up with. Is it still at Ford?
Ok so Mallon in Tacoma called (2.5 working days later) and said they are 90% sure it is a connector from the Alt. They said it was only delivering 3-4 as opposed to 12. That explains why the system failed to charge but.....why such a huge drain (2 fully charged batteries) in 12 hours w/ out using the truck? To that they said....a we're not sure? So 4 hrs later @ $90 an hour they will fix the connector and wait a day/night to see if this fixes the problem. on a side note whenthe hell did mechanic rates go up too $90 a friggin hour? My sister is a lawyer with 6yrs of collage and charges $75hr.....
A bad connector would account for not charging the batteries, but not for loosing your charge while not in use. Unless that connector is allowing a direct short, you still have a problem. Keep us posted.

$90 is way too high. The guys who half rebuild my Audi drivers side, did get $46 mechanical and $65 electrical work. And this was not a Mexican shop, owned by a German, used higher rates than Insurance company used in their estimations.
These kinda "light service" guys should get paid like $36 max. You´re lucky that they won't charge from the night Light Service 24 x $90...

Your sister is obviously one of the good hearted lawyers, who tries to help people who need it. those Mechs are obviously the ones who also try to help someone, themselves.
How old are your batteries,have seen testers that don't correctly test a battery of that size
with alternator charging so much could have cooked batteries
as per hourly rate $90 aint bad where I'm at was $105 at dealer 2 yrs ago,western NC $65 3 years ago,thats the cheepest I found in years
But remember the mechanic only gets 40 to 50% of the rate and at $35 to $45 an hor it would be hard for him to survive
attorney here $250+
$65 an hour to test alternator figures to be $135+ per hr

Yeah, but here in the border zone you can find a mechanic $15/hour, maybe not qualified enough even for the "Light Service" but it is possible anyway. Your truck may loose some parts or good parts changed into crap in those places

You have two problems. Problem number 1 is your giving your money away to people that are guessing/playing with your money.
Problem 2, You have 1 good battery and 1 bad battery in your truck. The bad battery is putting a load on the alternator and sucking the life from the good battery. REPLACE BOTH batteries.
If you want to see this for yourself. Separate the batteries from each other. Test them with a volt meter. Better yet, find somebody with a battery tester that can put a load on your batteries (or $30 from Harbor Freight). You'll probably find one good battery and one bad battery. Problem is, the techs at Walmart and all the other chain places don't have enough knowledge to know to separate them, they work with gasser motors mostly that only have one battery. They just don't know any better!
Wal Mart x2 batteries $65 each = $130 install yourself so you know its done right = happy truck and no more problems.
My 1998.5 Has A Intermittent Light Knock I Think Coming From The #8 Injector (i Think) I Was Told That Need To Replace#8 . Then Someone Diffrent Advised Me That It Will Not Hurt The Engine, And To Leave It Alone. I Have 80,000 One This 7.3. The Truck Runs Great Besides The Knock. Thanks
