I disagree about "wonky" let me try with more diagram and less English: (+8) | VIN| ceramic cap |-----][----- ___|____ | | 7805 |----------GROUND -------- | | | VOUT|(+5) | | | ___|____ | | LOAD |-------| -------- +8 is not currently available (no pun intended). I would like to test LOAD without removing 7805 as it is soldered in place. Is damage to 7805 likely if alternative regulated current is applied at (+5) and (+8) is left open? Bill S.
