98 12v Electrical problems

Just got the truck back together and I'm having some electrical issues. I have two brand new batteries and all connections are clean and tight.

When starting, truck is slow to crank sometimes. Also, the speedometer bounces all over the place. Lastly, the windows and accessories are really slow as if there is low voltage. Tonight on the way home, all gauges died and the dash lights were really dim. Then gauges would come back. Voltage is showing 14 or so on the gauge.

Any ideas? ECM....? How do I test it?
