Does anyone knows at what voltage a relay cuts out? I want my generator to start in my toyhauler at aout 10.5 volts. Any lower voltage and it will not electric start. Does anyone know if I use a normally open relay if at around 10.5 volts the coil would de-energize and close the contacts allowing my generator to start? If not, anyone have any ideas on another way to do this?

You could try to modify this circuit.
