nyquil junkie 280 #1 Posted April 19 (edited) As per my thread in the other forum, this is my dead auction win from the other day, a 314-A with the K321S engine. Seems all there, all the wiring looks original and unmolested. Problem, it has no spark. It'll crank if you turn the key to On and then jump the starter post. But if you turn the key to start, nothing. Before I do something stupid, is there some common point of failure somewhere that will 1)kill the start key from cranking the started and 2) kill the spark?

gwest_ca-(File Mod) 12,273 #3 Posted April 19 Looking at these diagrams? If you download the 4-page file one of them shows the start circuit and another the ignition circuit. This one is not what we normally see. The pto must be off OR an operator in the seat for the ignition switch to be powered by the battery. 1 Share this post Link to post Share on other sites
nyquil junkie 280 #4 Posted April 19 Ah ok, I see it has a starter solenoid. (duh). We piped some gas to the pump (main fuel line is plugged up) put the key to on, bridged the selonoid posts and bingo... runs like a new one. So, I need a solenoid and, maybe a new ignition switch if it doesnt hit the new solenoid. Thanks for that wire diagram. 2 2 Share this post Link to post Share on other sites

Before you go out on a shopping spree check the fuse holders and fuses. There is a 30 amp fuse between the battery and the ignition switch and the battery acid fumes fro battery recharging will corode the fuse holders over time. To see if the solenoid is good run a small jumper from the small terminal on the solenoid to the battery + post, if it cranks over the solinoid is good. A little trouble shooting can save you some money. 3 Share this post Link to post Share on other sites
nyquil junkie 280 #6 Posted April 19 Good advice, thanks. Clean those grounds and fuses. I had to do that exact thing on our old 8N ford's solenoid, when I drug it home, it had a bad ground....a few min with a wire brush and it worked fine. You would think I would have thought of that in this case but, I didn't. 3 Share this post Link to post Share on other sites

hotajax 270 #9 Posted April 20 (edited) I'm not saying your key switch is bad. But if it is the key switch, you can buy those things for cheap cheap cheap. I got one at Lowes for peanuts. It was XYZ brand, but it has been doing the job for 20 years now. Edited April 20 by hotajax Share this post Link to post Share on other sites
