Ummm, what's wrong with that? I = E/R: 66mA. This
(static) current isn't blowing the fuse.
Yes.
I thought it was a SHORT ! Not 76 ohms ! Looks like there may
be hope yet.
well i tried the light bulb load ( using a 6v lantern flashlight
bulb) and using a lattern battery as power source.
i could not find anything warmed and the DMM milliAmp meter shows
~ 138 mA
i get ~438 mA when i disconnect the light bulb ???
and the 8051 IC is the only thing that is warmed but no nore than
it warmed before the 32v rail mixing with the 5v
i do not know what this means , hopefully something good
