its a 10uF, 16V cap ( typical in circuit boards etc )

also the battery is a good condition 1.2AH 12V

also i did NOT pre-charge the cap

still @ 12.66V ( but i have a feeling its going to go to 12.67 )

amp draw @ 0.399 mA now

i put the scope on it....

putting just the positive probe of the scope ( ground of scope not attatched to anything ) onto the positive of the cap.....gave an AC signal...about 50Hz ( our AC is 60 Hz here )....but it was modulated up and down like crazy.... RMS value of voltage was about 112mV
