Yes I swapped out retrievers and it still blows the limiter. Changed both the unwind and rewind relays and still pops the limiter. You can hold the switch either to full unwind or rewind and it will not blow, but if you bump the switch 6 or 7 times pretty quick, it will blow before you know it. I dont see how it can be the control relay but that is the only thing left to change. I cleaned all the contacts including the common ground and it didn't help either.
Any other advice? This trainer is used for loadmaster training and has been a problem for quite a while.
