Recovering the charge from a system yesterday. Left for a moment to grab a cylinder of nitrogen from my truck I came back to, what I thought was smoke pouring out of my SMAN3 gauges. I freaked for a moment thinking the gauges were internally on fire, but quickly realized they have sprung a major leak somewhere. Recorded it real quick, during the vid was when the almighty light bulb came on and I realized it was venting, not smoking.
Usually don't use them, but my other set decided to start leaking yesterday at the sight-glass on the prior job.
Had to stop recovery, worried I would be sucking air in through the gauges. Just connected the recovery hose directly to the unit..recharged system with my other gauges.
Russell...trade you a new set of SMAN4's, for the intellectual rights to the laser tachometer head I suggested you guys make
