78 3/4 ton 454...

new battery, new battery cables. Just clicks. The voltmeter reads upwards of 15 volts while running, drove it around to try and charge up the battery, but when i kill it, it just clicks. Is this the starter? I am running out of ideas here!!!!!!!!!!!!!

If your cables are good & the engine is grounded good & the battery is strong
it is a problem with the starter &/or selenoid. Is the click loud & comeing from the starter area? If so it,s time to pull it off.

clean with sandpaper andor wire brush both ends of both battery cables and the places they attach to then reassemble with a smear of dielectric grease on each connection
amazin things happen with clean electrical connections

As stated above I'd make sure your ground is good. Where is your - batt cable connected to? Just because it is new doesn't mean you have a good ground.

I recently had the same problem with my '77 GMC dump truck with a 427.

I replaced both cables and made sure I had good clean connections and the problem went away.

It looked like the cables were the original ones and actually undersized for their length.

If you have checked the connections and they're ok, my vote would be for a bad solenoid. When mine was started to go out it would click loudly when you started the truck. Have you tried bypassing the solenoid with a screwdriver? If that gets it to start then you've found the problem.

new battery, like i said. very clean posts. the ground is to the alternator bracket (the original place?)

Pretty sure its the solenoid. I bet it got too hot. isnt that a pretty common problem? thats what ive always heard. Im thinking baout going to a mini high torque starter
