    Again - no expert - From my understanding, the suggestion to start on one module, predates the introduction of "Soft Start" (SS) . It was a potential way of achieving a soft start. The fitting of the SS system (2 modules & a flywheel) should remove the need for this obsolete technique (if it ever had any effect). -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501783#501783

    I concur with William Sullivan - would go further to suggest making sure all ground/earth wires have continuity. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501784#501784

    Yeh! sounds like a restricted fuel flow which could be the filter, blocked tank breather or like Dashwwoodlock, blocked fuel line (particularly at tank exit point) -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501785#501785

    Wow! I always understood the coolant temperature to be the MAXIMUM not the minimum - you might want to get this checked out. Most land based vehicles have coolant temperature sensor located in the head or thermostat housing - both high temp areas. That your temperature reading went down when airborne - suggests reduced coolant available - check level and as JH said check for air in system. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501786#501786

    I assume, your system uses Allen key cap bolts drilled for safety wire. Should this be the case, do the bolts up "snug" then safety wire them to prevent movement. If not drilled for safety wire - suggest you do so. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501788#501788
