Dolphin Troubleshooting is simple. Don't even bother taking apart the motor compartment. Besides having many many screws, you just can't get replacement parts so save your time.
If your robot stops moving, you MUST shut it down until the problem is corrected. Failure to do so may burn out your drive system.
You MUST check for toys or other objects such as acorns that may be stuck in the drive track causing it to stop.
These little things can get stuck behind the sideplate and jam the drive system causing irreversible electrical damage.
Prevention is key to your robots health because if your robot breaks, you are going to pay with LOTS of down time while the robot is sent for repair.
The Dolphin power supply differs greatly from Aquabot. Aquabot transformers only step down the voltage to deliver A/C current to the robot. Dolphin steps down the voltage AND transforms to D/C with an internal circuit board having diodes. I believe this circuit board is one of the few user parts available.
To check your Maytronics Diagnostic power supply, use a multimeter set to 200vdc. Output voltage should be about 38 volts D/C.
A known exception, the Robo-Kleen power supply puts out about 30 volts A/C, you read correctly...A/C.
