Overcharging problems

Thanks for the explanation Matt. I called for replacement battery and he told me current battery is 2016, so could be toast? Core charge was $5, so I'll keep old one for now(use in boat??). With new battery hooked up, I was doing some "checks".
There is continuity from battery +ve to the VR case??
Shouldn't there be continuity from the -VE to VR case?
Thanks
Steve
I don't know Steve. Not sure what you are doing or testing for. Are you using a powered continuity tester? Measuring ohms with a meter?

The voltage from battery + post to any ground, including the regulator case should be the same as the voltage from the battery negative to positive terminal.
