I have a DMC1 and no fast tool. Found car at bottom terminal with doors open. Ran on insect up/dn. Went through interlocks - poor contact on some. Some pick up rollers clipping. Observed and returned to service.
Car ran for about a half hour and went down again (found at bottom terminal w/ doors open again. Car calls latch, power is applied to doors, then car immediately goes into viscosity. Viscosity runs for about 2 minutes, times out and pump stops.
Rebuilt i2 valve because it was bleeding all over the place - screens are clean. Tooled with low pressure a bit which sends car into viscosity sooner if turned in. Everything seems fine except that low speed doesn't drop and I don't get high speed.
Any clues? Not sure what I'm overlooking.

Hold on.
"Low speed doesn't drop and I don't get high speed". That alone will no doubt MLT the unit.
Typically a DMC when found with doors open will indicate door lock issue at that floor. Most faults will close the doors. Monkeying with the low pressure adjuster will cause the car to move up, level down, move up then level down or, not close the up side properly and LOOing the motor/ valve circuit. You may have created yet another problem by goofing with the valve.
Check clutch clearance to bottom floor pick up rollers, check for door ramps on door hanger tracks causing the interlock to open up if the car/hall door drifts open. Also when on viscosity, peek through the passing jamb to see if the car is indeed moving up (it shouldn't).
And lastly, does it run up at all on auto? Broken TSL wires are common on the DMC which will allow it to run up on inspect, but just bump up but not run high or slow on automatic and going LOO or MLT. Without the FASTOOL you don't know if it's viscosity or trying to run up high, then timing out. Check the TSL wires in the switch tree.

Thanks gentlemen. Checked TSL wires in tree switch and found that a wire was corroded under terminal and barely hanging on for life. Missed it.
