Low Battery warning on radio

When I start the truck the radio flashes a low battery signal, and the lights and radio shut off. About 20 seconds later they come back on.

New batteries? Or should I get the alternator tested?

I'm spread kind of thin right now and dont really have alot of time to dedicate to this, so any help appreciated.

new batteries in place. Didn't really have time to get them tested. Hopefully they solve the problem.

When I start my truck the voltage drops to 11.8 untill the fuel heater shuts off and then climbs to 14.1 or so.
Been doing that ever since I owned it 3 years ago. Have 2 alternators that equaly charge at 30 Amp each at the time.

That drop is from your glow plugs, i believe in 04 or 05 they stopped using the fuel heaters.

OP - Fix your problem?

truck fired up this morning like a champ.

I am guessing that one of the batteries has been fading over the last couple weeks. As it has been having sluggish starts recently.

FYI- the low battery signal on the radio went away in about the same time that the glow plugs turn off. So I am guessing the one good battery didnt have enough juice to keep the glow plugs, lights and radio going.

Same thing happened to me. Started to have slow sluggish starts had my batteries load tested and one of them wouldn't hold a charge at all and put out absolutely nothing. was about as useful as hooking my battery cables to a block of wood lol replaced the batteries and now she fires right up every time
