OK, so we're talking your 9N, right? Is it the original 6-volt/positive ground system or a 12 volt job, meaning, a 12-volt battery and 1-wire alternator? Electronic Ignition added? FWIW, all 9N and 2N tractor starters never had a solenoid. That's the round can that sets on top of the starter like your 8N. Now, define "hi current switch". If you mean the starter solenoid, then it has been swapped out with a later 8N style and a bit more surgery done to the wiring. If you are trying to describe the Safety Neutral Starter Button on top of the case next to the shifter arm, then that's a different animal. A clicking starter is a typical sign the battery is dead. How did you verify the battery? Just by checking with a VOLT/OHM Meter isn't a true test. The battery needs to be checked on a proper tester, usually only found at auto repair and starter/alternator shops. The tester will check it UNDER LOAD to verify it will take and sustain a charge. You need AMPS to crank your engine, not VOLTS. Think of it this way: Take a 6-volt dry cell battery or 4 D batteries, or 4 AA batteries, or, anyway they all equal 6 volts but have very low amperage. You couldn't start your tractor on a setup like that. Here's a LINK to JMOR's Wiring Pictograms from our HOW-TO's forum. Scroll down til you find yours. If you don't see it, yours ain't right because he has every conceivable CORRECT wiring configuration possible, whether 6 volt or 12 volt or EI.
