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 👍
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
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 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.
Some progress discovering a rotted red wire on driver side behind all switches there is a fuse box for all the switches and another one with just 3 glass fuses a red yellow connected to the selenoid and black 2 Amps 250V I'm trying to find the fuse holder but is impossible. I will try tracing the wires to see where they go what they do the yellow is attached to the selenoid.
@@elipsonj Sorry, wrong info. This is a Snap On Pro Link Ultra using the included round 6 pin connector for J1708 diagnostics. Our Snap On tool guy installed the software, but I am sure we had to pay for the software.
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!
@@notyours1612 if it has a regular brake fluid reservoir, then it's hydraulic. Is the fluid full? Does the brake pedal just go the the floor or is it hard as a rock?
@@notyours1612 If it drops to the floor that usually means there is a leak in the system, but you say the brake fluid is full. Seems like the master cylinder where the reservoir is may have failed or somehow you got air in the system.
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
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 ..

Good to see you, Johnny! Congrats on diagnosing the problem and getting Thunder back on the road!!!
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!👍🏻
It’s a feeling of total relief
The $400.00 relay... :-) We should donate thanks for the info. I Feel like I learned about the wires on the firewall.
Good job Thanks for sharing
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.
Thanks so much That’s a great to the point video

Hope you get it resolved soon! These things are expensive.
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😅🤯

Yes. Check for power and ground.

That’s awesome. Where did you find the relay? Can it be bought at autozone?
Yup. Standard 5 prong relay.
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.
If it's clicking, but not cranking, then the starter could be bad.

$1,000 tow 25 miles 😩 I’m still trying to diagnose it.
Good Job, but What snap-on scanner are you using?.. thank you
Modis
Thanks, What adapter did you use and does your Modis come with the software for international school buses?

Air or hydraulic brakes?
@@JohnnyMullet air I believe. Has a regular Brake Reservoir.
@@notyours1612 if it has a regular brake fluid reservoir, then it's hydraulic. Is the fluid full? Does the brake pedal just go the the floor or is it hard as a rock?
@@JohnnyMullet It just drops to the floor. Reservoir is full. Thank you for politely correcting me and responding to my message 🫂

Start with the batteries. There is fuses on top in holders. look for melted fuse. Then try relays on firewall like I did.
aha kinda confused I wish you recorded doing the job
