hey. looking for some imput if anyone could help. have a clark gcx25e here at the shop. vin gx230e-1513-9372fb. one of the tech here before me did a headgasket in it and when he set the timing he had it a tooth off. it had been something i had been meaning to get to for a bit, but couldnt find time. a couple days ago it quit running so i figued then would be the best time to dig into it. before i began looking into to no start condition i figured i would get the base timing set. set the base timing then started diging into no start
No start condition- no start no spark at the coil.
the lift has a mitsubishi in it. tested the coil. primary and secondary windings are within spec. the eternal resistor is within spec. air gap on ignitior is spot on, vacuum advance is working properly. tested the ignitor (icm) when cranking it is creating a 10Hz signal (right where it should be) but it is not flashing a ground for the coil. checked the grounds on the lift. engine to neg, distributor housing to neg, chassis to neg, etc are all 0.1 ohm key off and around 3.4 ohm key on. i have used a jumper wire from battery negative to the head and to the distributor housing just for *** with no change.
if i tap a ground jumper to the neg post on the coil it will spark with key on so i know the power side and the coil are both working properly.
im sure this will be somthing simple and right in my face, but if anyone has any insight on what direction i should head besides pushing it into the brook and buying an MCFA product that would be great.
