I'm still building my MS1 v3.0 I've just installed the above components and I think I may have shorted them. I was wondering if anyone could tell me the resisatnce on there ms between the B and E on Q 14 & 15.

It seems strange to me that I manage to short the same two pins on both components one after another when all my others have gone in fine? I'm hoping the circuit operates this way and I don't have to try and take them off the board and re-fit.

Thanks

Also is it correct to jumper R39 as the sticky in the how to build thread shows the resistor in place not a jumper.

 

I posted the same question over 2 years ago when I built my MS, and basically that's normal for Q14 and Q15. If you look at the schematic, what's between the transistor legs you think you shorted are R37 or R38, which are only 0.5 ohms. Your meter might not have enough precision in that range, or just show it as continuity like mine did. You should measure the same resistance for R37 or R38 by itself as you do across the transistor pins in question.

 

mines shows continuity between them. (due to the reason Scott posted)


R39 is jumped if you're running the idle control mod.

 

Thanks very much for the quick response. Glad I've not ballsed it yet!
