When a Frog Juicer is activated, the LEDs change color, and the turnouts seem to be functioning perfectly, but then an intermittent short circuit occurs that results in the DCC system shutting down. If the power to the Frog Juicer is disconnected, the DCC system re-activates, and when power to the Frog Juicer is re-connected, it functions properly for a while, but then it fails again. Could the Frog Juicer be defective?
Diagnoses & Solution
While the Frog Juicer may be defective, it is more likely that there is a wiring or frog isolation problem.
A simple test is to disconnect each frog one at a time from the Frog Juicer and re-test the functionality until the problem no longer occurs. This will narrow down the issue to a specific frog. Once you have found the frog that is causing the problem, swap the output of the problem frog with the output to a frog that is working correctly. If the issue disappears, then the Frog Juicer is likely at fault.
If the problem still occurs, check to ensure that the frog is fully isolated.
Sometimes putting a 0.2 ohm, 1/2W resistor between the Frog Juicer and the frog will also solve problems. You can use a 24″ (61cm) length of 30ga wire to replace the resistor.
