![]() ![]() The only thing I can come up with is when this engine got warm or hot the resistance went up and the voltage did not pass accrossed the block. The engine also had some oil/dirt mix from a leaky valve cover that I believe contributed to some of this issue helping the stray voltage. The engine ground was pretty clean, but I cleaned it up some more. This was crazy and I will probably never see it again. I got frustrated thinking it was gonna turn out to be something stupid and unrelated and sprayed the wires while it was running and discovered the arc on the coil. I could unplug the 02 sensor at start up and it wouldn't error out with a false driver error. However it seemed to travel through the o2 sensor and back to the SECM causing it to throw code 29, but only when everything was cold from sitting. ![]() What I actually found today was that even though this unit would run perfect and start right up, the main coil wire would arc at startup and was sending voltage acrossed the block which should have been dissipated by the block to battery ground wire. I tested the amp output from the SECM to the electronic throttle body and it fell way below the 5amp maximum. Thanks, I had done the wiggle test and tested each sensor. Achieve greater performance and lift your productivity to new heights with the Doosan G25N-7 IC-Pneumatic Forklift. Any help or insight would be appreciated. Im thinking the internal battery in the secm drains down and the secm has to reset itself on that first start up. I am thinking that this power is missing as this only happens when the lift has been sitting for a long period of time. Leavitt Machinery has over 2000 pieces of used equipment in stock. Does anyone have any good schematics for this or can they tell me which pin/wire color going into the secm should be a constant 12v keep alive power. I did get a new secm and the unit has a new throttle control unit on it. Turning the unit off several times and restarting it will usually work after many attempts. The no throttle will happen from 30 seconds after start up to as long as 5 minutes. Today however I checked for a battery constant (keep alive) power wire to the secm and did not find any. I have checked over the harness for rub through damage. There is also a second control box on this unit under the dash that ties in with the throttle control. This driver fault would be the 5v reference signal that is coming out of the secm from the information that I am seeing.
