i am having trouble with coil on fork lift
its an oldy 1966 towmotor with those 4 cylinder Chrysler motors.

we would have spark then not, have spark then not...
so i replaced the coil- at first no spark, then spark... so i suspect it is wiring or some other component failing and not sending signal to it like it is supposed to

i followed the ground wire from it to a small lil metal box that has hand-writing on it that reads TP 85 Control;
so i am guessing Terminal or Touch panel...so i looked inside it is alike a gel substance that 6 wires run into and go several different places - alt, starter, coil, and distributor -

i have never seen such a box, like that- with the gel and wires coming out of it... anyone know what that might be- anyone know if i can maybe run ground directly to it- i suspect not b/c if so it wouldn't be going through that gel box.

any one with ideas/suggestions?? so greatly appreciated
