Unhappy Battery light

Hi everyone.
Last night while I was driving the battery light on the dash was coming on and going off. The voltage gauge stayed steady. If the truck was idling the light stayed off. If the engine was reved up the light would come on. This morning the light will not come on. This is a stock 2k 250 4X4 extended cab. The only excessory is a remote starter. Anyone have any ideas?

I'd start by having the batteries tested, 2K is still about 5 yrs of life if they are the originals.

If u have A voltmeter the batteries should be 12.5volts with truck off and no more than 14.5volts while engine running.

That sounds like a classic case of terminals needing to be cleaned. Some arm$hammer, 1/2in wrench, pair a pliers and a knife should do it.

Side note. Hope they are good battery cables and not the cheapy type. Those will cause all kinds of problems.

I cleaned and tightened the battery terminals and it made no difference. I also checked the batteries. I load tested both batteries and the passenger side is getting weak. Since then I removed a bunch of wiring from under the dash. The truck was used as an ambulance and I think the wireing was for running the lights and siren or for a remote starter. I also found the clip to the signal light harness was broken.I repaired the harness and I have had no problems since but I am worried the problem will come back.
