I have a 2001 Terex tb42 that kicks out every 10-15 seconds after the foot trip is depressed. Works fine for that time frame then controls kickout and motor returns to idle. Simply letting off the foot trip and steppingback on it gives you another 10-15 seconds ofcontrol.
I’m assuming that it’s sensing a condition that’s telling it to quit operating but what? Fluid levels are all good.
I also have an intermittent fuel pump issue. I’ve bench tested every relay in this thing and all test good passing continuity between 87 and 30 when 86 to 85 is energized. Jumpering 12 volts to fuel pump will allow it to run no problem. What conditions would tell the control board NOT to energize the fuel pump?
Help! I’ve been working on this thing way too long!
