Ok just in from testing.
I think it's functioning properly, though still unable to check current.
With the truck engine running, but the charger off, I read the same volts at the starter battery, the Anderson connector and the charger input (14.3V). I believe this indicates no voltage drop due to wire size and length. The trailer house batteries sit at 13.06 (approx 50%).
When I then turn on the charger (via marker lights), I get the same reading at the starter battery and the Anderson (14.3 V), but at the charger input I read 13.3V. The charger output reads 13.58 V and the house batt's 13.38V.
Dip switches are configured to 14V output.
After a few minutes, the starter battery read 13.46V (same at Anderson), 12.58 at charger input, 13.58V at output.
So even though voltage dropped at starter battery (smart alternator?) and charger input, it stayed constant at the output.
The spec sheet for the charger states an input operating range of 8-16V.
So I think it's designed to deal with fluctuations due to smart alternators while maintaining appropriate output voltage.
I welcome any comments.
Thanks.
