01 7.3 stalled at traffic light
While running errands today in this scorching East Coast heat wave, I had the A/C on max with the fan at the highest setting. The truck suddenly stalled. I switched the A/C to regular mode with the fan on level 2, restarted it in neutral, and it ran fine afterward.
The O/D light was flashing immediately after the stall but eventually turned off. All of my fluid levels and engine temperatures are normal.
One other thing worth mentioning is that my rear differential has an occasional slip and has a small leak. I’ve been keeping it topped off, but I haven’t checked or added fluid in a little while. I already have a complete rear differential rebuild planned.
Could running the A/C on full blast have put enough load on the electrical system to cause this? When I scanned it, I also got codes for the input and output speed sensors. I replaced both of those sensors a few months ago, so I’m not sure if they’re related or if they’re just a result of the stall.
Any ideas on where I should start looking?
