BLINKING RED LIGHT!

[joek]

ok, i am helping out a rookie team, when i hear that they are having issues w/ their jag. when i go over there, i hear that the device the jag controls got jammed, and i also see that the jag has a flashing red light , and won't do anything.

what is wrong, and can i fix it?

[gr8dragon]

I have had only 2 experiences with jaguars and its at once.
We had a similar problem with them last year but the problem was that it only did this for one direction of speed control. We figured we burned the jags and just replace them with victor 884s which are still legal.

Good luck with the issue.

Depending on the speed of the flash it is either going backwards at less than 100% reverse or is having a code error. The slower cadence is the code error one. Use a voltmeter to see whats coming out of the motor side of the jaguar.

welll... i think that it also smelled kinda like it does when u solder electronics

[The Lucas]

The flashing red light indicates an error state. The error state I encounter the most is a low bus voltage error when the drive stalls out or the main battery runs too low (both easily fixable). Of course this is one of several possible errors.

I suggest you replace the battery and disconnect the motor from the jag. Confirm the jag is operating correctly by watching the indicator light. If not operating correctly replace the jag. Otherwise your problem is probably elsewhere.

tell me more about this voltage error, it's possible that that could be the problem, otherwise, it's probably fried

Just follow the suggestion about disconnecting the motor, replace battery etc... See if the jag works with no motor attached. Then you know if it is the jag or the motor that is the problem/smell

The motor is drawing so much current that either A. the jaguar is holding an error condition to attempt to save itself from certain destruction under the full 129 amps of a stalled CIM (something the Victors don't do) or more likely B. the battery cannot supply that at 12v and so the voltage dips low enough to reset the Jaguar.

[joek]

so... if it is reset, how do i un-reset it?

[Vikesrock]

A stalled CIM or FP can each pull enough current to trigger a Jaguar overcurrent fault. If the mechanism is stuck you will likely have to manually unstick it to see if the Jaguar is still working.

As The Lucas said, observe the jag lights with no motor attached. If it does not fault, then the mechanism is stuck or the gearing needs to be changed to draw less current.

i will try that, btw, if you can come over and help me, i'm in the other regional (williams), it's the robostangs that are having the issue, it'd help a lot. if you do, tell them that joe set you, and that your there to check out the jag

[Vikesrock]

We're in Northstar at Mariucci, same as last year. Looks like you guys are in 10k Lakes in Williams.

If it is a Northstar team that needs help, either find me in the 2175 pit tomorrow morning or let me know the team number and I'll see if I can make some time.

[joek]

it's williams, just come to 2052, and ask for joe (me)

You do realize we have been using Victors for years with the CIM motor right?

If you are still having problems, come and find me or ask the LRI at your event. I am working both sides of the street in Minnesota and can be in your pit in a few minutes.

well,,, comp is over, wish i'd checked this earlier
