P1633
Hey guys!
I have this 2008 f550 6.8L V10. Recently got the code p1633 and lost power when stopped. Battery and alternator both read 14 amps. Could it be the fuse?? I’m not too sure what to do so any help is appreciated. Thank you

One possible cause for the P1633 code is a weak or faulty battery. Start by inspecting the battery and its connections. Ensure that the battery terminals are clean, tight, and secure. If there are any signs of corrosion or damage, clean the terminals using a battery terminal cleaner and tighten them appropriately. A weak battery may need to be replaced.

Hope that's some quick help late on a Friday night. A voltage problem existing from the Battery is hard to trace, you just need a VOM and look for bad terminal connections and grounds. also the Fuse boxes do have corrosion problems also. Blue green is a bad sigh on need of new stuff. If you are uncomfortable with this, just call your friendly neighborhood skill shop that you trust. U'r looking at a possible + $300 +.
