help with pressure switch adjustment

[vaughany]

Hi everyone, I have only just found this site as the problem with my system 1s has only just happened. I will admit to knowing very little regarding the systems and even less regarding the installation.

I was in the engine bay today and I noticed a screw that was loose so I tightened it. However what I think I tightened was actually the screw to adjust the boost pressure that activates the WI. I thinked I turned it about 4 full turns, the system was set at the preset 10psi previously. I would like to reset this value but I wanted to know if there is a way I can do this accurately. I have read that I can fit a LED and use that as an indication and then adjust the pressure accordingly.

Unfortunately this is not fitted yet, is there another way such as totalling unscrewing the screw and rescrewing in back in a set amount of turns that would roughly set it at 10psi. Also I have checked the site and am fairly sure that the screw i turned is for the boost pressure but I am not entirely sure, the screw in question was the tiny screw in the middle of the 2 connectors that run from the battery. is this the adjustment screw for the boost pressure switch. If anyone has some pictures etc, this would be helpful

I hope someone can help me with this dilema, the only good thing that has happened is at least I have now found this site and can gain some knowledge on the system.

many thanks
