foligno 08-16-2009 07:29:41 24.244.242.102 95819 Report to Moderator	Hello, I have a Scotts 1642. The other day after I stopped it during a mow, it would not restart. It now only clicks once each time I turn the key. I bypassed the solenoid with a cable and it turned the engine, so I replaced the solenoid. I now still in the same boat, one click. What the heck else could it be? Battery is fully charged. I also have an issue where bypassing the solenoid will turn the engine but will not start it. I assume this is something else...? Any help greatly appreciated! :) [Reply]   [Send Email]

Clamp to negative - connection to solenoid from battery - light. All other connections at the solenoid from the negative battery post - NO light. I tried it with the key in all positions - same thing. Does that mean the new solenoid is bad?   [Reply]   [Send Email]

You need to trace the wire from your starter switch whether it has a push button or a key to the solenoid to see if your light is getting battery voltage. If your lite glows & shows voltage is at the solenoid you probably have a defective solenoid. Hal PS: If you have safety switches on that tractor one of them may be defective. It may have one on the neutral start or seat. You can jumper these to isolate the switches, but I wouldn't operate the tractor with them jumpered.   [Reply]   [No Email]

Another piece of test equipment is a fused jumper, use a low amp fuse. connect one end to battery, touch Start terminal, if solenoid engages, the unit is good, switch / wiring bad   [Reply]   [No Email]

I"ll try to answer everything I saw up till today here: First - The click is happening not at the solenoid, but rather somewhere seemingly in the centre of the engine itself. Sounds most like it is near the fuel line/filter. Definitely not at the starter though. Second - thanks to your responses, you tweaked me to something. The safeties. All seemed ok and disengaged. All connections looked clean. However when the engine was cranking when bypassing the solenoid, I had to have the seat up and didnt push the clutch pedal in. I disconnected the seat safety just to start it and engaged the clutch/brake lock. The missing part of the equation for me was that the key needed to be in the ON position. After that I did manage to start and mow last night, but if I had to stop the mower I had to bypass the solenoid each time to start it again. A ROYAL pain! No way I can get my kid to do the job like that :) Some ideas left that you guys had that I havent tried/explored yet yet: 1. Possible bad solenoid. Think I should just exchange it and see? 2. Ignition switch - how could I test that? I would put my skill level at this stuff as beginner but not newbe. Thanks for all your help! :)   [Reply]   [Send Email]

Use a volt meter and see if voltage is getting to the solenoid when someone else makes an attempt to start the engine. Be careful around that flywheel when doing this. What you're doing is bypassing the starter switch when making a start. One of those small terminals on the solenoid is used only for starting. Hal   [Reply]   [No Email]

If the lights go out, something is providing insufficient current, (bad cable/ground/switch). Your test says the starter is good. If you have a volt meter, measure the voltage drop across the starter with the key turned. It should be near 12V.   [Reply]   [Send Email]

Or a bad ground on the solenoid? Or the new solenoid you bought is bad?   [Reply]   [No Email]

Customer says the tractor wont restart after they ran outta gas. Is your parking brake on? Are your blades engaged? Frank   [Reply]   [No Email]

Are we fer sure thats where the click is coming from? Could be the fuel cutoff making the click. The Fuel Solenoid clicks when the key is turned on or off. You can hear that when the tractor isnt running. Frank   [Reply]   [No Email]
