It blows instantly, no time to see the voltage, not at plug in but at
start up, any idea where the red and brown plug marked DG goes ? dressed
pretty heavy, bottom side goes towards the fly back area, I fear it may be
bad and probably should be replaced but I can't check and have no print,
wish I did, actually have a paying customer this time !!! thanks for the
reply.
