2000 Ford F250 super duty 7.3 power stroke
 

I recently replaced both batteries in my truck as they were about 5 yrs old and I was having a slow cranking situation in the winter--- truck still exhibited a slow crank speed after replacing the batteries--- went to start the truck today and all the dash lights /chimes/dome light went on just like normal ---waited for the wait to start light to go out turned the key and total darkness but dome light is flashing on and off and a clicking sound even with key removed from ignition coming from the left lower dash area---closed door still clicking--- thought maybe I had not tightened the battery cables properly so i cleaned both terminals and posts again re-tightened everything got in the truck and everything was normal all the dash lights were on power door locks worked etc.---tried to start and same symptoms as before---is it the GEM ??? or maybe the fuse box??? looked for moisture by the floor/fuse box area nothing, no wet carpet so does not look like any leakage anywhere--- anyone got any ideas??? Thanx FED 387

Still sounds like a bad battery even though they are new. Do a individual load test to verify.If it has a programmer that was installed thru obdII port I would put stock tune back in it. My slow crank was from bad starter, but no flashing lights just slow turning over. Starter is easy to remove and have auto parts test it. Have you tried key on and jump solenoid at fender to see if start up?

Just saw this on powerstroke forum, but sound was near radio and not on left side of dash:

The clicking was coming from under my dash - just under the Radio. I ended up pulling the Panel that exposes your fuse panel - then under the AC and Radio there is a cluster of wires plugged into 3 relays. 2 small relays and 1 large.

When I would try to start the engine I could feel the clicking sound I heard from those relays..
I squeezed on the three relays and tried to start the engine and it worked. However the next day I still had the clicking sound and no start..

I took the 2 smaller relays (both being the same - part # F57B-14B192-AA) and swapped them with each other. Putting the Top on into the bottom slot and bla bla bla.

sound might be under radio didn't look that closely but I was pissed ---by disconnecting and reconnecting both batteries I am essentially re-setting every thing ---you would think that the lights locks etc would come back on maybe not enough voltage turn the starter but the clicking sound is new never ever have heard that before--- this is a one owner truck I have owned it since new no MODS whatsoever chips programmers remote start stuff nothing so this was kinda surprising--- I changed the batteries about 5 years ago they were getting old and going into winter did not want any surprises/problems and at that time no of these problems arose---FED 387

I might add the truck doesn't crank at all not slow nothing like its totally dead--nothing works other than the clicking sound and the dome light flashing off and on---

Key on and jump solenoid on fender well? That would bypass ignition switch on bottom of column. Volt meter on batteries when attempting to start to see if they're is s draw?

Are you in a freezing climate area ?
Most Diesel engines need to have the block heater plugged in to stop the fuel from jelling . It will also cause a very slow or no crank situation.
Anything below 30deg will cause a diesel to have a hard start issue

Did you get this truck fixed? If so what was the problem just in case it happens to me or others. Thanks Jeff

Ends up I had 2 problems. First one of the brand new batteries was defective second the wire from the solenoid to the starter motor was corroded about 1/2 way thru. If u wiggled the wire while on the starter tester it would maybe turn over but most likely not. Ended up replacing the bad battery and put in a new starter wow fires right up just like brand new. fed 387
