Hi John, Either only one core is passing the electric current or the air flow is not sufficient to avoid the heaters to reach the temp where they increase in resistance enough to self-limit the power (so they don't burn up) Can you see / check the two elements to see if they both pass current? If so, then the air flow must be increased to get higher output (and lower the heater core temp, so they will draw higher current).

Measurements show that I'm getting about 2000W of heat total when the fan is on hi. Even though each core is wired for 240 VAC, and I'm driving it with 327VDC. Wonder if these actually draw 1500W when plugged into AC? (too much of a PITA to check mine now.) -- Worlds only All Electric F-250 truck! http://john.casadelgato.com/Electric-Vehicles/1995-Ford-F-250 _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
