curious as to low current draw as measured

also note, must turn pump on/off with switch in DC line, not AC line or pump often fails to restart (as documented by Iwaki)

Iwaki calls for min. 22v to start, haven't tested that yet
Definitely draws more than 0.7A, no matter what you're doing. Would suggest that clamp-on meter is very faulty/inaccurate. I measured my current draw with two different in-line meters.

Pump starts just fine down to as low as 14v.

[Edit: Are you measuring the DC or AC amperage?]
