Hi John,
Thanks again for this project. I just hooked the buffer up and got a RED light. I did run some engines that were always susceptible to interference like my K-line 2-6-6T and it had NO flicker at all with good response of commands.
The readings I got were: base signal - 1.085, output signal - 10.37. Any thoughts on what I should do/check?
Thanks,
Greg

First off, is this a Legacy or TMCC base? The TMCC base will usually get a red light and a few of them get the "no light". A good Legacy base should give you a green light.

I agree with Chuck, something is very wrong with the readings, with a known good Legacy base I got 1.88 volts DC for the Base DC reading and 5.4 volts for the Boost DC reading. Given the circuitry there, that's about what you should see. 10 volts on the Boost DC reading is knocking on the door to impossible! What kind of meter are you using?
