Yeah, I can't find any solder problems either. Did you assemble your MS yourself?DGFTurbo wrote:What pads were bridged?

So, you fixed your problem? And you were having the same problem? 5V out anytime the MS is powered?keithmac wrote:2 pads on the fuel pump transistor were (just) bridged with solder, I didn`t assemble my board either..
First step would be to replace the fuel pump transistor and check it`s orientation I would have though?

What about on the V3?keithmac wrote:Its Q3 on the v2.2 near the db37 connector.
I think had a constant ground problem with mine, never checked the output of the pin just had a close look over the board where the transitor sits.
