So I haven't checked for AC noise yet, but I read Hz on both my God cars and the one that's acting up. Not one of them read anywhere near 1200Hz. The closest I get is 98 or something, but it bounces around so Ican never get a good read. I can't seem to locate the terminating resistor in the shaft, but to be fair, i haven't fully gone through car 3s shaft yet. So I tried disconnecting every RS board i can find in the controller and the car. I then read to ohms on each network. To my understanding, I should have on rcbs p5 plug somewhere around 100ohms...ish - that's terminal 2-3, 4-5, & 7-8. I plugged them in one at a time and read ohms and I happen to be good on every board. except i question 7-8 since I'm only getting about 60 ohms. However, when I power up, the problem returns. When it does, I pull my p5 connector off, ohm through each network, and find across 7-8 I have 170,000 ohms. Which makes me think I'm having car network issues. Could it be one of my buffer boards? I'm not sure how to test one of those. I'm also getting a 1709 fault - which is something about a car stop switch override on fire service I think. Again, making me think something with the car
I'm going back Monday. I'll start with the ac noise. I'm at the point of just throwing boards at it. Hell I've already replaced the software 😅
