Bus Breakdown - Diagnosis and Repair 

Welcome back Johnny! I miss your bus videos! You being a mechanic is definitely a gift. :)

You are so knowledgeable about diesel engines. I’m quite nervous about taking my bus out on the road. Thanks for the video.

Oh man ! My Bus stopped so I’m checking what you did ! Thanks for sharing Johnny ! From Mobile , Alabama ..

Glad to hear it was something simple and not too costly. The $400 tow bill was costly enough. Anyway, I’m happy you got your baby back on the road!👍🏻

Glad to hear it was just a relay,good job on the diagnostic. My 1991 is a mechanical inline six and I just bought a 2001 with a t444e,definitely a little intimidating with all the electronics.

Thats the shit that really piss's me off!!!!!! F**Kin cheap relay!!! $400???? Thank you very much for showing this information. Im sorry you went through this. Knowledge is key, And theres so much to learn. Keep ur running , All the Best 👍

Good to see you, Johnny! Congrats on diagnosing the problem and getting Thunder back on the road!!!

The $400.00 relay... :-) We should donate thanks for the info. I Feel like I learned about the wires on the firewall.

Thanks for the reply, the starter is in good condition i jumped it with a push button and is turning. I will try the relay check for power etc tomorrow

400 buck 40 miles... sign me up for that.. I was hearing like 600+ just to hook up.

Good job Thanks for sharing

I'm having the same problem with a 95 blue bird bus no crank it's driving me crazy I've been going through all the electrical for 3 days now😅🤯

Thanks for the video!! I love your bus. I have a similar compass on m hood as well. 1987 International 6.9 L IDI I have a no start issue that has taken me down a rabbit hole. I’m looking for a wiring diagram for the bus console panel.

Thanks for the information. I checked all the fuses, over the battery, and inside as well, all good. I unplugged the relays and made a 12v battery relay tester and can hear and continuity test the switching is working. So seems not my fuses and relays. The concept I don't completely understand is how to test the power lines on the harness plugging into the IDM/ECM. A video on testing that with a multi-meter would be helpful or at least an explanation for someone like myself who is learning. Is it as simple as turning on the key to ON, and sticking a Red positive prong in voltage mode into the harness power wire port, and Black prong into the ground port and monitoring for 12 volts?

That’s awesome. Where did you find the relay? Can it be bought at autozone?

That was a most excellent, informative vlog, thank you sir! I learned a few useful tech tidbits for my '97 8-window IH T444E 3800. Too bad that simple relay cost $400, but all our problems should be so simple! No flash button on my dash, tho. Any thoughts on where Thomas may have stashed it at? 🤞 HazMatt from the Skoolie forum

Thanks for your good video, I wonder if you had this problem that I have, it clicks by the driver side but no crank batteries are fully charged also power booster brake motor not making any sound when you apply the brake All help is appreciated.

$1,000 tow 25 miles 😩 I’m still trying to diagnose it.

Good Job, but What snap-on scanner are you using?.. thank you

Thanks l have check this fault

Hoping you can give me some info. I have a 1960 School bus with rear Widowmakers. Had the tires replaced and upon driving home found I had no brakes. Any suggestions would be greatly appreciated. Brakes were fine until tire replacement. Thanks you!

One question, my truck starts but it doesn't go more than 20mph, I have the following codes 114, 223, 622, you have any suggestion for me, engine t444e 1997

aha kinda confused I wish you recorded doing the job

It’s a feeling of total relief

Thanks so much That’s a great to the point video
