black jags not showing a solid yellow light
Last night our programers got a base code loded on the crio and they tried to move the moders but the new back jags are not showing any indication lights so I was wondring if they could be burnt out. I think someone might have cross wired the electrical componets and turned on the robot without having the wiring dubble checked any sugestions. Finaly we have tried all the pdm slots on the sidecar

Re: black jags not showing a solid yellow light
With power added, but no pwm cable plugged in the jaguars should blink yellow.
If they are not blinking yellow then double check the power input with a multi-meter. If the input power is ~12v, but they do not blink then they are probably broken. There is an RMA process available for broken Black Jaguars. |

Re: black jags not showing a solid yellow light
There are some other posts where teams are reporting issues with black jags that are not working. Any possiblity that there is a production issue?

Take this as an engineering problem and run some numbers. 5,000 Black Jaguars were shipped to teams in the KOP. More have been purchased through Digikey. Production runs do have a standard error rate, probably less than 1%, and quality control would pick up on that. That would mean ~50 Black Jags that might normally be expected to have problems. That would mean ~ 20-25 teams would normally be protesting that their jags aren't working. So far we've heard only a very few teams out of 2077 complain. We've seen nowhere near even the NORMAL number of complaints you'd expect with a less than 1% production error rate. Luminary Micro published an error report after 2009 based on the number of units returned to them that you can checkout. The vast majority of the failures were due to usage, not out-of-the-box bad Jags. There were a few out-of-the-box bad Jags though, so don't be surprised if perfection isn't achieved. |

Will reversing the polarity fry a Jag?

Do all of the black jaguars not work? It's unlikely that every one is wired backwards, so it might be some other issue. |
