Hoping someone can steer me in the right direction. 450C Cummins engines. They both crank very slowly at start and I have been trying to track down the issue. Batteries have been load tested, have looked for bad connections, checked the air preheaters and they are successfully bypassed (was suggested to me they can draw a lot if not functioning properly). Changed out the seawater pumps recently and started the engines to see check for leaks and they fired instantly - I had forgotten to unplug the boat. It was night and day different in crank speed.
Battery charger seems to be working. If batteries are good what else could it be? I'm not good with electrical at all, help!
