I have a 1998 Dodge Ram 2500 with a Cummins diesel. I get in it, turn the key to the on position, all the lights on the dash flash, as they should. I turn it to turn the engine over and everything shuts off as if the battery died. The clicking noise comes on signaling the battery is dead. I hook up some jumper cables to a friends car and the batteries won't hold a charge. I was suspecting a short in the electrical system, but I'm not sure. I need major help.
Sounds like you need new batteries. Diesels require a lot more cranking power to turn over. If you replace the battery, or batteries, (my truck is also a diesel and has two) and the problem continues, you may have a bad starting solenoid. You will want to deal with this quickly. Bad batteries, and solenoids put extra strain on the starter and could cause it to fail. I would take your batteries to O'Reilly's and have them tested, take it from there. I hope this helps.
I agree put some batteries in it and go from there.
