2003 Ford F-250 Powerstroke won t Crank, won t start.?

when I turn the key, I get a rapid clicking noise, and the indicator lights on the dash flicker. Glow plugs also sound like their barely getting enough juice. No crank at all.

I hooked up my 100w solar panel with a automatic12/24 volt charge controller, which said batteries had a good charge. Went ahead and charged them fully, followed by cleaning the post, and battery connections of corrosion.

Result was the same, won t start.

Any ideas what could be wrong?

You seriously think you can float charge a set of dead 850 CCA batteries with a solar charger, then you won't be moving soon. Get a real 10 amp battery charger. The second standby battery is on a battery isolator so it won't charge both at the same time as the main battery unless you charge on the isolator alternator B+ post on the battery isolator.

You need a new battery. Just because it takes a charge, doesn't mean it has the amps to crank the engine.
