Gluing PWM connectors into Motor Controllers

[feverittm]

I was talking to another one of our mentors the other day and he told me something interesting.

I have always (past 4 years of FIRST electrical) that it is a good idea to put a drop of hot melt glue on your PWM connections on the motor controllers to keep them from falling out. This is especially true for older Victor style controllers whose connections can become loose.

However, he told me that 'gluing' the PWM connectors is illegal as it counts as 'modifying' the controller.

Does anyone know for sure? I wanted to make sure before we decided to follow this strategy and maybe make a mistake.

Thanks
