Re: Full reverse on jags problematical

Thanks for pointing that out; I meant to say that they don't immediately trip, whereas Jaguars do.

Well now... I had originally suspected that your Jaguars had been mis-calibrated (with regards to this, can you confirm whether or not the LEDs flash yellow when you "disconnect"?), but this is a whole new can of worms.

More questions:
When you cause an individual Jaguar to fault, is the breaker that trips the one that corresponds to the Jaguar you're faulting?
Have you tried testing what happens if you fault exactly 2 or 3 Jaguars simultaneously, instead of all 4? If so, what happened? If not, please try testing every combination of 2 and 3 Jaguars that you can and record the results.

Also, can you answer Joe's and Kevin's question about your DSC wiring setup - that is, is the 12v power supply to the DSC properly connected?

If you could upload a detailed picture(s) of your wiring configuration, or possibly even a video of the condition when you get back to school, that would be helpful too.
