I just had the power shift rebuilt in my 7020 and now it drains the batteries when it sits. Iv been trying to trace it down with my test light between the battery ground and ground cable but haven’t had any luck. If someone has a wiring diagram that would sure help. I found a post on here but the pictures don’t load at least not for me. Mines a black belly. Any help would be appreciated. My light goes out when I unhook the big red wire going to the cab from the circuit breaker but that doesn’t narrow it down much.

Do you have a digital/electronic radio?
They can take a battery down if not wired correctly. What kind of alternator? How's the wires to the alt? |

First thing you want to do is test and inspect the Batteries themselves. You could have a Battery with a cell going bad or a bad cell in it and its draining itself. And, if its connected to another or other Batteries, it'll bring them down also. Put a slow charge into the Battery(s) for a day or so. Then do a draw test on each one (if more than one) and see if the problem is at the power source not the Tractor. If you pull a draw and they hold rock solid, then you can at least eliminate the Battery(s) as the problem and continue to troubleshoot the system to find your problem. If you have a Battery thats borderline, do a hydrometer test on each cell and check it out. So many times our customer's pull their hair out trying to find the problem with their Tractors depending on whether its a charging issue, drain problem, whatever, and here all the while its the Battery(s). The Battery is always overlooked. But its new! Doesn't mean a thing! New to you...... HTH
