Hi. I have 4 new AA batteries in series that result in about 6V. It passes through a 5V voltage regulator (IC3) and a few capacitors to remove high frequencies as shown in the attached image. When I attach the third electrode of the voltage electrode to ground, I smell something burning. Why is this? I remove the ground connection and when I remove the four resistors, the voltage at V1 comes close to 5V as I would expect. When I include the resistors, the voltage at V1 drops to 3V. Would you explain to me why and how I can avoid this? I thought that the resistors were very large compared to the battery's internal resistance, so V1 would not drop.
Thanks in advance for your help and patience with these beginner questions.
