Title: Connectivity Check/Question
Post by: ddog on March 21, 2014, 06:26:27 AM
So Im building the Electric Boogaloo and I got a solder bridge between pins 6 and 7 of IC1. I cleaned it offbut Im still get connectivity signals from my DMM. I checked the schematic maybe there is supposed to be connectivity?

Here's a link

If so what I am not getting is that I am not getting any connectivity between 1 and 2 on IC2 (I soldered the resistor in)

pins 1 and 2 have a 10n cap between them so it will block a continuity signal.

pins 6 and 7 should be connected so you are fine there

Whew thats a relief. I was ready to start cutting traces.

How about 1 and 2 of IC2, the one with resistor. Should there be connectivity there?

Well IC2 pins 1 and 2 are connected by the 220k resistor so yes they are connected together but you shouldn't get continuity between them (hence the resistor blocking the signal.
