First Programming - Victor/PWM help

[popnbrown]

Unfortunately, no.

I just checked with the multimeter again and just poked around (literally) in different ports on the Digital Sidecar. There's 6V from the V+ to the black on the PWM out ports. 0V between Sig and (-). 0v between Pwr and (-). On the Digital IO, however, 5V between Pwr and (-).

Any suggestions Ether in troubleshooting without an oscilloscope?

Do you have a known good Talon or Jaguar?

Give it some 12V power and plug your PWM cable into it. See what the LED does.

When you are issuing a "full throttle" (forward) PWM command, you should have a duty cycle of approx 20% (2ms pulse divided by 10ms period). So your multimeter should read roughly 1 volt across the white (SIG) and black (return) PWM wires. Use the DC setting and observe proper polarity.

Yup...I removed all the PWMs and checked them, it's giving a 0.75 volt reading in neutral. So it's working correctly.
