Jaguars not working

[RyanN]

Checking the continuity is only part of the testing procedure.

First off, to prevent any more damage, make sure everything is wired correctly. Make sure the polarity to the Jaguar's is correct.

The Jaguar's suffer from a somewhat fatal design flaw. There is no information printed on the Jaguar itself to indicate battery input, motor output, or even the polarity for them.

Here's a picture from the Jaguar manual to show how to wire it.



If you have verified that is correct, then power on the system and check the voltage at the points shown in this picture.
NOTE: Wiring in the sketch is just for demonstration. Don't use it to rewire your robot accordingly.


If no voltage is at the Power Distribution board, make sure you have the circuit breaker in the right spot, and if it is, try to move it to a different section.

My best bet is that the Jaguar's are wired incorrectly. In that case, they are probably toast.
