Troll Master, any body have one ??

[Bduck]

If yours does not have the on off switch Curt is describing it would be best to put an on off switch on. Then if you’re voltage ramps up or down, say with a dead or charging battery, your control unit is not getting below specification voltage.

Here is a pic of my troll master, Chuck must have a different model, if it doesn't look like this, on/off switch is clearly visible.

This is the same as mine. Its upgradeable to the Pro 3. The original basic model I started with on my last boat did have the on/off. The servos can and do burn out but also can be purchased at a model/hobby store without buying a complete new Trollmaster kit.
