My tender says its 37% after sitting a week. Then it tops off in about 30-40 min with a 3A maintainer / charger. Brand new auto tend / charger.

Just tried all 3 testers. Newer one does say 1.3A across ground to neg post on batt. I'll track this down. Thanks.

Update. Pulled every fuse individually. No change.
Me, I'd suspect the alternator diodes and pull the connectors to the alternator and check again. Don't let them go to ground when checking or you'll smoke the electrical harness.
