Re: [FTC]: Broken Fuse/Broken (Tetrix) Battery?!?!?!
If the lights turned on momentarily then shut off, I'd be willing to bet that the main fuse did blow.
There should be an inline fuse holder on the positive lead of the battery. Open that up and take a look at the fuse inside. It's easily replaceable. You can buy packs of 5 for about $3 on Mcmaster-Carr with the part # 7460K517 or at your local hardware/automotive store for under $10.
Did you turn the power on while the robot was enabled(NXT was sending motor commands?) If the robot was not enabled, check your wiring as there may be a short somewhere along the system, causing the fuse to blow.
Here's what I'd do to check the electrical system:
1. Unplug all but the first device in the chain
2. Power on.
3. If power does not die, power off and connect the next device in the system.
4. Repeat 2-3 until your entire system is tested.
If power cuts out after you connect a device, then the problem lies in that device.
One other thing I'd check is your battery connection. The Tamiya battery connectors have given my teams some weird problems if they weren't seated properly.
