What causes a battery light on a Ford PowerStroke?
So, for the first min or two you won’t see anything over batt voltage so the alt is being saved from being overloaded trying to recharge the freshly cranked-down batteries AND the load of the GPs (over 150A) Good catch! I had mine on too. Ended up being a funky thing with GEM modual.
What kind of battery does a Ford PowerStroke have?
My multimeter reads 13.5v on both batteries with the truck off, 12.5v on. Replaced the alternator, still same results. What else can I check to get this stupid light off???
Why is my battery light flickering on and off?
(Flickering lights, dead/low batteries, etc.) If you’re sure the batteries are OK, and you’ve changed the alt already, I’d be giving All the connections and related wiring a real good look next (especially the alt plug) for signs of corrosion. FOUND IT!
What causes a 13.5v battery light when the engine is running?
A static 6 cell 12v battery (like we all have) shouldn’t be capable of producing 13.5v… If you’re seeing 13.5 with the engine running and 12.5 OFF, that makes sense and actually shows the alternator is doing something …
