Chevy Can't CRANK...After Alternator Replaced?? ('04 Silverado V8)

We're on a road trip to Western PA today to diagnose a beached whale Chevy truck.
Owner said that a month ago he replaced the alternator, then the truck started having weird electrical issues, and finally REFUSED TO CRANK!
He's been trying to solve the problem for a MONTH, replacing the ignition switch, fuse box, and testing the starter.
Let's diagnose the root cause of the NO-CRANK problem, and see if we can get this Chevy back on the road NO PARTS REQUIRED :)

The TS100 deserves all the screen time it gets. Awesome tool. Another NPR diag from the master using a test light, wiring diagram, and scanner. Love this channel.

[@ovalteen4404]

It's worth noting that in the aircraft mechanic field, butt splices are strongly recommended over soldered connections because solder is brittle and can break in a high-vibration environment. When solder is used, it should also be well supported to prevent flexing anywhere in the vicinity. And of course, butt splices should be high quality, barbed types that actually want to hold on to the wire, not Dornan crap.

Ivan I have now been watching you for years. I have learned so much from you and have become the family and friends car electrical problem fixer. You have saved my family thousands of dollars. I really enjoy and am thankful of your channel.

[@fredmalito9869]

I’m curious how everybody solders wires together in these types of situations. For smaller gauge wires, say 14 gauge and smaller, I strip back an extended piece of wire, twist it, create a hook, and hook the two sections together. I then use “genuine Amtech flux“ That would make Alex at Northridge Fix proud, solder the hooks together open parentheses making sure solder flows on all exposed copper), and then use adhesive heat shrink over that. For larger wires, and I mean anything up to 2/0 gauge, I use tinned butt connectors with the appropriate crimper (hydraulic once I get to 8 gauge and bigger), and then use the above mentioned the flux and solder to finish the connection inside the butt connector. Then I finish with adhesive heat shrink. I use the same method for terminal ends as well.

[@bashdavid9223]

Yeah I’d never solder wires without the wires intertwining beforehand let alone in an engine bay where there’s a lot of vibration. This solder will eventually become undone. I would sacrifice having a lumpy section in the wire over wire breaking 😂

WRT hot food on the road, a friend of mine made himself a small metal box and managed to fix it to the exhaust manifold on his car. He constantly gets looks of amazement when he pulls into a parking bay, opens the hood and retrieves hot food from it! He developed this idea after once heating a pie that ended up plastered to his engine after he drove thru a pothole! 😀

[@Just_D.I.Y.]

Way back that was actually a thing, wrapping food in tinfoil and leaving it on the engine to "cook" while on a trip. Never tired it, but saw it advertised in DIY magazines when I was a teen.

Even if i don't like the "fix"(newer solder car wire's they fail) it was great find and good for some time use.

Awesome job as usual!!! Thanks Ivan!

[@cclngthr]

It is amazing what a bit of corrosion can alter voltage and current. On my Corolla, I have a digital volt meter on a USB charger that I plug my guardian angel emergency light and my phone into. I had noticed the voltage drop slightly (while within spec on charging system) while driving. I already changed out the negative battery cables to 2 gauge and 4 gauge from battery to chassis ground and engine to chassis ground because i have an amp and sub in the car, but had not done anything to the positive battery cables. It was down to 13.6 volts, but I wasn't comfortable with that when at startup it was 14.5. What I found on the 2 positive battery cables, which are stacked on top of each other and clipped together, was some dirt/corrosion and sticky film between the 2 terminal ends. I removed the stock positive battery terminal which has one point of contact for the cables to attach to the terminal, and I changed the terminal to a better one where I could separate the positive cables onto 2 separate attachment points on the 1 positive terminal. Now at startup the voltage is at 14.3-14.4 volts and at idle after 35 minutes of driving and in park with lights on the final voltage is at 14.2-14.3 volts.

[@williamcunha9136]

[@theadmiral5425]

That soldering iron is the bomb...I use it all the time.

[@billbarney4937]

i had a 25 year old car with lots of open wires. the reason: the auto manufacturers use the smallest gauge wire that they can get away with which for most sensors/switches is 28 gauge incredibly thin wires. i had a no crank no start and found an open wire feeding the starter solenoid

I would definitely buy this soldering iron though.. The regular cheap plug in style don't get nearly hot enough.

[@glenharper3136]

[@thogevoll]

What was the final state of the "key in ignition" PID? You commented that it was still not active with the key in while you had the broken wire bypassed but I don't think you returned to it after the repair. Apparently the immobilizer doesn't care; it must just be a switch contact in the ignition switch so repairing it is not necessary. It's not like newer vehicles that have to read a chip in the key.

[@blueskiesmobileauto4253]

Great find Ivan! I’m thinking of trying out the Milwaukee solder iron. Cordless might be the easiest way to solder. I often have a rule that will go no outdoor butt connectors only indoor above feet level. Our salt runs deep here.

[@truracer20]

Damn, I bet you hate the fact that the factory connectors are ALL CRIMPED*? Do a proper crimp and seal the connection and it can be submerged in salt water problem free. I will never ever trust someone who admits they can't properly crimp a wire connector but can solder one. It's like saying you can feed yourself but can't wipe your ass. A properly completed connection is a good connection. And in my experience in vehicle fleet maintenance, solder is not appropriate in most cases. Wires trend to break at the edge of the solder. In a well crimped connection the wire strands still have the ability to move throughout, in a solder connection they don't, all movement terminates at the solder. *splices are connections but aren't connectors.

I admit that I can't properly crimp a connection, but can solder and shrink wrap all day long 😂

Ivan, good job on getting this identified and repaired. Did you resolve the key in ignition fault? Seemed it ran fine even though it didn't recognize the key was in the ignition. The reason I ask, is that I'm using the Thinktool Pros S scanner and sometimes it identifies faults but the car is working fine. Seems like you can spent a lot of time chasing issues that may or may not improve the situation.

Being food safe certified you are going to want to make sure your food is above 140F (60 Celcius) to keep it food safe otherwise a maximum of 4 hours (I wouldn't go over 2 hours to be safe because you may not know how long a hot food wasn't kept to food safe temperature before you got it) if its anything less than that. Just so you don't get food poisoning. This would be internal temperature of the food not surface temperature. Do some experimenting so you know if core temperature of your food is maintained.

Question on the soldering iron: do you also run RC "toys"? Looking into a battery similar to the one you have to run the iron it is around $30 but to charge it it appears one needs a special charger and that is another $60. If used it at least a couple times/week I would just bit the bullet but I am a casual user. Willing to buy the battery but wondering if there is any alternative to purchasing a dedicated charger? I bought the soldering iron thinking it was portable like built in rechargeable battery but discovered it is not portable unless you purchase the above items. Love the iron (used 3x so far) but disappointed it isn't really portable out of the box
