Testing a converter?

For a very BASIC go/nogo test: Connect batteries, plug into shore power and check battery voltage; DC voltage should be between about 13.2 and 14.5. Lower, converter is not putting out, higher, converter is putting out too much voltage.

This is a very basic test, and does not really test how well the converter is able to preform.

Set your meter on DC and measure at the battery
You are looking for voltage at least 13.2 assuming that batteries are currently charged
High charge should be over 14v
But if they have been charging for several days, the converter should be in float mode, and that is 13.2v or slightly above

You can easily check output by measuring voltage across the battery terminals when the converter is powered. The voltage should be > 13 V. Meter is set to DCV.
