I should have been clearer. The ammeter instructions say a run should go from one terminal of the ammeter to where the battery cable attaches to the starter solenoid, and from the other ammeter terminal to the BATT connector on the key and to the OUTPUT of the alternator, i.e., that terminal has two wires running from it, one to the BATT on the key and one to the alternator OUTPUT. That way all the current in the igniton system passes through the ammeter, and the drain or charge on the battery system can be monitored.
My question is, how can this be done and also monitor the drain to the DC panel if that connection does not also go through the ammeter? There must be a way to view the total system current, right? Wouldn't running a lead off the BATT post on the key to the DC panel ensure that that current (whether it comes from the battery bank alone or from the alternator output) passes through the ammeter and is measured?
