M542 Driver

[Jonathan]

If you can find what the component is connected to that should make it fairly obvious...

My guess is that he put the supply wires around the wrong way. I want to replace this first before i can apply any power to it.

That's easily done as different drivers put them different ways round - if I recall correctly the 2M880n is the other way round. I've got some pictures of inside a 2m880N, but unfortunately they're mostly out of focus or too dark to see anything useful:



Just out of interest which mosfets does the 2m542 you have use? The one I looked at has IRF9Z34N

LOL, that looks like my 2280n!

Let me know if you need any pics of it...
