There is no legal fix for their existing motors - only for preventing new motors from burning out.

Could anyone using the Tetrix fuse protected motor power cable answer a couple questions:

1. Does it prevent burning up the Tetrix motors (eg. live up to its promise)?
2. Does the fuse act like a circuit breaker (eg. when it cools down it works again) or do you need to replace the fuse/power cable once it has prevented a motor stall ($9 vs. $30 for motor)?
3. If it is a "fuse" that is destroyed while preventing damage to the motor; can just the fuse (hopefully less that $9) be replaced on this cable without violating the FIRST rules?

Thanks.

The fuses being mentioned in various places are part of the battery pack. They are mini blade types and reside inside that black bump on one of the wires coming out of the battery pack. If your motor(s) are not running, check the fuses first. Either remove it and check for continuity or just check the wires out of the battery pack for voltage.

A team update has allowed us to use lower amperage fuses. We're currently running one motor on a 4A fuse. I recommend getting a few lower amperage fuses at the very least. I cannot tell you anything about the thermal protector that is available. I also await reports from those who are using them.

Warehouse,
The $9 Thermal protector is an auto resetting device. The smaller fuse in the battery is not a resettable device and will need to be replaced when/if it burns open. I am sure your mileage will vary on either device. The failures are caused by various designs and the stall characteristics each provides to the motors.
