I know I there are a couple other threads on here about the red flashing light on a jaguar but none of them helped me know where to check for the problem. I saw something about undervoltage and I checked the wires and it was 12.09 V.
The Jaguar works in one direction but when I tell it to go the other direction, the lights starts to go the right direction but then turns into a slow blinking red light. I know this isn’t a good thing but I don’t know how to fix it.
Are you using black or grey jags? Last year, when using grey ones, when we would try to abruptly change directions, the jaguar would overcurrent and go into a fault condition. After a little while does the jaguar reset and go back to working?
We fixed this by putting a limit on how fast the robot could accelerate in code. It worked (or you could switch to black jaguars, which didn’t do this)
That sounds like the “limit switch” feature.
Check your limit switch jumpers. They are the two vertical jumpers on the far right, shown in the image below: http://kamocat.com/photos/jag_colorcode.png
(This Jaguar has been marked up for better visibility)
We had the same problem with one of our gray jags, and someone else on CD has it also. We ended up just declaring it dead (maybe use it sometime for a unidirectional motor).
Oh yeah, ours started smelling bad after a while of running it backwards.
Well to my knowledge red flashing is either slow reverse or an overworked motor. I found that out the hard way. It might be the limit switch or check the motor to see if it is not jamming and any point.
Morton,
It is possible that you have mechanical issue. It runs fine in one direction and then binds in the other. Are you driving one of the window motors with this controller? The window motors have locking pins that could prevent movement, particularly if you are driving two motors on a common shaft.
