Relay amperage for side car

[jfitz0807]

We have our digital sidecar connected per instructions. We're still having trouble with relays. We're trying to drive a servo, but it's not moving. We have a button set up to toggle the servo between 0 degrees to 90 degrees. We are printing the value we are putting in to servo.setAngle and also the value getting returned by servo.getAngle(). We can see that on a button push, we are setting the angle to 0 and it returns a small value close to zero. On the next push, we are sending 90 degrees and it returns a number close to 90. Next it's back to 0 etc. Unfortunately, the servo is not moving.

I checked the voltage between PWR and Ground terminals on a digital IO channel and got 2.5 volts. When I check the voltage bewteen PWR and Ground on a relay channel, it reads 0.0.

I'm stumped as to how the servo can be sending back approximately the right value without actually moving. Also, what should I expect to read with a volt meter on the relay channels?

Any insight is greatly appreciated.
