Build and Intro

Thanks for your help. Its appreciated.

The day before last a spent the day going through the driver, taking mosfets out and checking them. Well using the test you posted one of them gave different results compared to the other 4 I tested. I left 3 in there as I assumed they would be still working , ,maybe I should have tested those too as its still not working?? Anyway I replaced the bad mosfet with a new one and went to try it straight away and the fuse blew. Am I meant to test the other two smaller mosfets on the upper side of the board with the rest of the circuitry?

I had a bit of trouble measuring the resistors. The first one is 0.05 ohms(from colours), which seems very low to me. Not even sure if you can get them that low? I then tested the other two resistors which have much higher resistance (going by colours) and they came up at about 1 ohm resistance if I remember correctly. The thing is though I measured the same resistors out of a board that was working and they gave the same readings. Starting to think maybe my electrical meter isn't working properly.

I'm also wondering why the over voltage protection didn't do its job also?

Cheers
