T650 Codes

Still having problems with the T650- dealer says it's because it has a non-Bobcat battery (Napa). Was going to take it over for them to check, not it won't crank at all, even at 14 volts. Codes M6507, M1706, M2721, M0521

The brand of battery does not matter. It's the power it provides. As long as it is within the specs and is good condition it is fine. Most used machines have aftermarket batteries in them.

Not sure what you have checked on the machine but do have the battery load checked.

Clean the battery terminals, and all grounding points, and make sure they are tight. Check the battery cables for damage or swelling under the insulation. Make sure the grounding points do not have paint under them from the factory (this has been a problem with some machines). Look for any rub throughs on the wiring harnesses. Clean and dry wiring harness connections (water infiltration has been a problem on newer machines). Make sure your alternator is working properly.
