Default truck wont start...

I have a 99 powerstroke, I just replaced the altenator, both batteries and i pulled the gem module let it sit in side warm up and dry out. when i put the module back in i covered it so no water could get on it. All my problems I had with the gem disappeared. It worked great for two days now I go to start it and it will barely roll over. The batteries are reading like they have a good charge and are sitting where they would if the truck were running. I have no idea where to go from here.

check all major grounds and power wires for each battery, and the power lead wire to the starter. They tend to rust out. If the truck is rolling over slow, it is a power or starter issue, not a module.

I didnt think it was the module, but before i was getting every symptom of the gem.. crazy light issues, insane battery drain, screwy speedometer, radio turning itself on and off and the blower kicking on on its own.

GEM is probably still draining the batterys. Put a voltmeter on it and watch it as you try and start it, needs to stay above 10-10.5 volts while cranking.

batteries arent showing any drain except for when i was trying to start due to the slow cranking.

You can't really tell much from battery voltage with no load, what does it go to while cranking?
