No Spark...Need help please....

[Chas]

So I had to replace my original starter and had a few problems doing it. To save lots of time detailing here I will cut to the chase....

I have it turning over and have no spark at the plugs now.....Im just looking for a place to start to check where the spark ends, and how to go about it....it ran well before doing the job so im sure i have a wire or something crossed and just need an easy way of running it down by process of elimination.

Thanks in advance , Chas:cool

Chas,
Are we talking points and coil, or electronic ignition? The older ones have the battery lug and two small posts on the starter solenoid. (newer ones only have 1, I'm told) The inside post engages the starter, and the outside one sends spark to the coil while it is cranking, and once it starts it gets power from the resistored wire. This is probably the mis-routed wire. Good luck!

The coil bypass wire isn't connected properly at the starter solenoid. The inboard small "S" terminal should only have the 12-ga. purple wire on it that energizes the solenoid, and the outboard small "R" terminal should only have a 20-ga. yellow wire on it - that's the circuit that carries power to the ignition while the engine is cranking. If that yellow wire isn't connected to the "R" terminal (or is damaged or broken), you can crank it all day and it'll never start.
