 I urge them to build the kitbot and repeateadly smash it into a concrete wall in order to sate their anger. It will soon wane when they manage to do more damage to the wall than to the kitbot. That is honestly the reason that we ended up using the kitframe this year. - Andrew Blair [more] |

Troubleshooting a jag
Can you safely connect a jag to direct power in order to see if it still works? It does not have the odor of a burned out electronic and no physical signs of damage. It is one of our new jags so i refuse to beleive it is burned out until i can prove it. Can anyone help me? Thankyou.

Re: Troubleshooting a jag
Before you go too far, can you describe the symptoms you are observing that make you think it is bad? For example, does the indicator light come on at all?

Re: Troubleshooting a jag
Am posting response for them as they are working on other things currently:
Light was flashing Manipulated joystick No response from gearbox (which may or may not have been due to a coding problem) Loud whirring from jag began (definately not due to coding problem) Rebooted system: Loud whirring from jag No indicator light No response from gearbox Opened jag case: No burnt odor coming from circuit board No obvious signs of bad or melted solder joints Fan spins freely Wires did not appear to be touching blades |

Re: Troubleshooting a jag
First things first, you can directly connect the jag to 12V with no breakers for testing purposes. If you have a CAN serial cable, you can use that plus BDC-COMM to do diagnostics on the Jag. Otherwise you'll only see a flashing yellow light without a good signal PWM signal.
Secondly, what color was it flashing when it wasn't working? Slow yellow means you don't have a good PWM signal or CAN network. Fast Red or Green means you're sending it a reverse/forward command. Slow red means there's a voltage, temperature, or limit switch fault. Thirdly, the whirring you hear is quite likely normal. That's the cooling fan. On a 2012 Jaguar, the fan runs for 1 second after power on, and runs whenever you're sending a forward/reverse command. |

Re: Troubleshooting a jag
Sorry guys, jumped to work today and this is the first chance we've had to get back to this. Will run the testing tomorrow and get back with you. Thank you for the advice!

Re: Troubleshooting a jag
Ok, so newbie question...we are using C++, how do we use BDC-COMM for testing purposes OR where can we find the info on how to do this?
BTW This is an inexperienced electrical team as far as diagnosing and troubleshooting anything more technical than faulty wiring and calibration issues... Nevermind. Just found the info I was looking for regarding BDC-COMM... Last edited by rsegrest : 28-01-2012 at 14:07. Reason: Hi-5 to face for not finding the info on ti.com first... |
