Modern machines draw 8A from the wall at the most. How do the GI lamps alone draw 15A? This I never understood. I know that four #44 bulbs is equal to one Amp and my machine has over 120 of these bulbs which would equal 30 amps. Where does all that power come from?

I believe you hit it on the head Superman. They aren't 110v bulbs. Thank you. The amps may be high but since the volts are low the wattage is lower than if they were 100v. Plus they are DC. So it has to be converted from AC by the Bridge rectifiers.

So lets say 40 GI bulbs in an old Stern Seawitch. The other 75 or so are Feature Lamps. 40 x 250mA = 10 Amps x 5vDC = 50 watts DC. Convert the DC to AC to find the draw on the outlet. 50 watts DC /110v AC < .5 Amps of current draw from the outlet I believe. Someone let me know if my math is wrong.

Pretty much all my knowledge about electrical stuff comes from working on my pins so there is a bunch of the theory or whatever I don't get yet.

Try these.

Man, sorry to hear about the bad GI circuit. Hopefully the LEDs will stop the problem.

I should order some LEDs.
