Alternator source for Alternators
Once Crimped, you can add solder to the crimp if you wish, I usually don't.
I like to use Heat Shrink instead, which you saw in the pictures on my batteries.

the jaws should be semi circular, been in my toolbox for decades.
they look something like this.
Here's the story:
I just picked up the Excursiontoday from the shop after another oil drip. They had it for two weeks to the day and had to reseal/replace the timing cover gasket, the oil cooler gaskets and remove/reseal the Morosso oil pan gasket. When I picked it up I noticed two things. First the back-up camera isn't functioning, most likely from a ground not connected due to having to lift the body slightly to access the oil pan. The engine started right up as normal but I noticed the volt meter was reading 13 volts. The shop did a load test before I left and the alternator read 12.99 to 13.0 volts. They also noticed the alternator terminal/wire was running hot and had a little corrosion where the engine wire harness meets the terminal lug at the alternator. There wan't much we could do at the moment as they would have to order a new replacement lug. I have to return the truck tomorrow morning to fix the b-up camera ground. While there I'll see if they can order the replacement lug.
I took it for a short drive and the volt meter read is now fluctuating from 13.1 to 13.7. Definitely a concern! When I arrived home is when I noticed the b-up camera not functioning and at the same time the engine felt like it wass lugging, almost dyeing when I press the accelerator. After the initial press on the accelerator the truck seemed to reverse fine. I suspect this is a result of low voltage. Too many coincidences at the same time (hot alternator wire, engine lugging while engaging reverse almost to a stall). The shop said they would evaluate it tomorrow morning.
Just two weeks ago the volt meter read 13.8 to 14.1 so I'm guessing the alternator is starting to fail as I've suspected before. Today I ordered a new Mechman 240 amp alternator part number 7796240. This should help the low voltage issue and hopefully the reverse issue.
Update..
Went for another drive this evening and now the voltage is back up to 13.9 to 14.0 volts where it was before. This tells me that for the two weeks not running in the shop the batteries must have dropped a tiny bit of charge. I would think if the batteries needed charge then the voltage output from the alternator would be at maximum. I surmise that the voltmeter getting its reading from the factory cigarette lighter is the system voltage and the reason the alternator power wire was hot must have been because the alternator was working harder. Although I did not open the hood to check, the voltage behavior makes a little sense.
The transmission behavior is still a huge concern. When I shift from drive to reverse, the engine rpm dips way low. After the initial dip in rpm's, reverse acts normal. My guess is a possible alignment issue that gets corrected during rotation reversal. Just a guess.
Any thoughts would shure ease my worries.
lots of places that wiring had to be disconnected, and replaced.
if the batteries had a Parasitic Draw on them while in the shop, they were probably fairly low, requiring a lot of amps to get them back up to 14.6ish area.
the alternator was trying to recharge them, and that is why the Alternator wire got so hot... and pushing a lot of current, revealed the power connector/corrosion situation.
any auto parts store will have lugs big enough to put on the charging cable, and the old fashioned Hammer Vise type crimp tool will do the job.
you will be very happy with the MechMan once it arrives, but make sure to add extra charging cable(s) from the Alternator to the batteries...
while you are at it, inspect all of the battery cables to be sure the connections are clean, and tight.... I spray all of mine with FLUID FILM, that way they stay corrosion free for years....

It’s the transmission reversing issue that concerns me the most. This is the second time that the body has been lifted off the chassis to get to the oil pan. The first time was early 2023 to address oil leaks and we’ve, they’ve been chasing them since. Hopefully this time they got it.
Here’s what it looked like in January 2023…
I hope my truck don't ever need to be lifted up like that.
so far, it is mostly stock AFIK, as it was a fire truck, so not modded up by prior owners.
it is slow to startup, typical of a starter motor that turns too slow, I have a new starter built up from the original frame that is supposed spin really fast... just haven't put it on, as the one in the truck always starts after about 5-10 seconds
it is possible, I suppose there is some oil draining back down, and the HPOP is a bit slow to get to 500 psi...
the 2002 trucks do not turn on the CTS-3 monitor with the key, a known issue... so I can't monitor ICP until after the engine starts.


Update:
Call from the shop, the batteries are now fully charged, the alternator wire lug is replaced and the back-up camera is fixed. The only thing left is why the engine is stalling when reverse is engaged. They suspect it's something electrical since the engine/transmission were't separated when the body was raised. They'll have it overnight and hopefully find the issue tomorrow. Stay tuned!

Not many have the equipment to do this at home. I don't think SSJ even has a twin post lift with a tall enough ceiling in a shop to make this happen.
From posted photos, most DIY guys show their cabs dangling from the buckets of front end loaders.
So I will probably continue teasing KBO76 about this until some more of you guys "level up" and get your shops built and lifts installed.
The shop installed a new lug on the alternator power wire but instead of using heat shrink, they used electrical tape. After driving about 20 miles the adhesive is already getting gooey. I'll fix that when I replace the alternator. The backup camera is working as it should and now the transmission is shifting into reverse correctly. Apparently when all the power was cut off and plugs disconnected from lifting the body, the computers needed to be reset. I went for about a 20 mile ride, checked reverse a few times and she's running like a well oiled machine. I can close this chapter and ready for the new alternator in a couple weeks.
when things go Wonky,
Power everything down, and let it sit for a couple hours.
it is just Amazing, now many Windows computers have been fixed by simply powering off the entire network, and computers,
power up the routers first, then the switches, then the computers....
lawsy be, it works now....
