My 1982 Ski Nautique won't start. Since I bought it 2 years ago, it's had an electical problem with the ignition. Sometimes when I turned the key, it would start with no problems. Other times, I would only get a click. Sometimes, I wouldn't even get that. This year, it won't start at all, so it's time to fix it.
Last year, I replaced the main cables from the battery to the solenoid (pos), and the engine block (neg). Just recently, I replaced the solenoid, and the starter. I have a fresh charge on the battery as well. If I use jumper cables to connect the battery directly to the starter, bypassing the ignition and solenoid, I can get the starter to turn. When I connect the battery through the normal routes (solenoid and engine block), the solenoid chatters when I turn the key, and the starter doesn't turn. I've isolated the solenoid and verified that it works by disconnecting the starter, and turning the key. The solenoid clicks, just like it should. I also isolated the starter, as I mentioned above, and know that it works. The only thing I haven't isolated is the ignition switch. Could that be the problem? If not, what else could it be? A short in the wiring from the ignition switch to the solenoid? It shouldn't be the ignition resistor, voltage regulator, or ignition coil. Even if those were bad, they shouldn't interfere with the starter getting the necessary current to turn the engine, right?
Any suggestions or insight would be greatly appreciated,
