Kent 1600 Xflow Engine runaway
Was helping a buddy time his engine so we set it at fast idle and did our stuff. Long story short, when it was time to shut the engine off (after running for about 20? minutes - thermofan had kicked in), it wouldn't. Ignition was off, killswitch was hot, engine still ran. Not dieseling, either - it never missed a beat from when the ignition switch was on and killswitch was cold. Here's the kicker - disconnected battery negative (ground) terminal.....and it still ran.
Checked the generic Westfield wiring diagram and I was thinking: could the alternator somehow have kept supplying juice to the coil? Because pulling one of the coil leads (I never got to see which one) was the only thing that killed it.
Since this is going the be an AutoX car, this condition could have serious track consequences. Anyone ever had anything like this before? If not, anyone out there with a guess?
Thanks in advance,
