Sanddrag, you said you changed the motor and transmission so I am suggesting that the assembly is misaligned or mounted in such a way as to increase friction and as such draw way more current.(enough to seriously load down the battery.) Check that all is correct and the hardware is tight but not too tight. I bet you find it.

We have never replaced a drill motor and/or transmission. Like I said above, we corrected the problem by fixing the chains which were scraping on the plate. The hardware was tightened so much that our nylon spacers under the pillow blocks compressed and lowered the shaft to where the chain now scraped on the plate directly below it. So, we added in a washer to raise it back up and we have been okay since.
