Good day I have an 08 f350 today I was driving down the Rd and my abs light came on for a sec or two then the battery light came on for a sec or two then all gauges stopped working as well as the heater. The radio stayed on but it was as if the truck had been turned off the power came back on a few secs later as everything was normal I turned around from a job we were heading to a went home on the way home it did it several more times. Does anyone have an idea of were to look or what might be the cause thanks

 

Might want to check your grounds and battery terminals

 

Thanks I will look today

 

So I cleaned all terminals on both batteries and still light cones on I then removed the positive cables from each battery while running to test if alternator was charging and still ran fine so I put them back on. I have now read the codes from my programmer and have a po625 code generator field terminal circuit low and a po155 code heated o2 sensor heat circuit malfunction bank2 sensor 1 I replaced the alternator about a year ago and batteries shortly before that
thanks for any help or info
