14 F-350 Electrical issues

Shelbygrow · Dec 29, 2018

I have a 2014 F-350 with almost 200k ******d and tuned. Last week the battery light came on with code P0625 charging voltage was 14.4 wile running. after I cleared the code it was fine for a few days. Then the dash lights and cluster started shutting off and coming back on wile driving. And I got a few other codes such as P0138B P0563 the 563 says system voltage high. When I checked voltage wile running I was at 14.8 any one have this issue before any help advise would be much appreciated. Thanks

I've seen something similar when the voltage regulator in the alternator goes bad.

On my 6.4 I had a broken wire at the alternator connector that popped a voltage too high code.
