Magnets are a tricky thing to fault find as you can do massive damage to many things if you are not very careful.

I would refrain from continuing to replace fuses until you have a plan of attack for rectifying the problem, perhaps replace the coils and driver transistors all at the same time???

sorry mike but unsure what you mean. Are these on the power driver? Forgot to mention using a rottendog driver thats a year or two old. I can replace it with the original for testing.

I haven't tried anything yet as figured there are suggestions that could save me a lot of heartache and blown components. Please advise next moves and will wait till then. Isolating the magnets is on m list.
