Sounds like the solenoid is sticking, it could either be the solenoid itself, the starter relay or the start button. You can test the solenoid by disconnecting power wire from the starter and hitting the start button, when you let go, check for voltage on the low current solenoid feed wire that feeds the start signal to the solenoid. If you get no voltage on that pole, test for voltage at the end of the starter wire where it would normally be connected to the starter. If the wire is still hot, then the solenoid is bad. If there is still power at the solenoid feed wire after you let the start button go, then it is either the relay or the start button. Next you need to find the relay if there is one, test that, and lastly test the wires coming out of the start button, see if they have continuity still after you let the button off.

      As the 2025 ATV Motocross National Championship Series (ATVMX), an AMA National Championship, got underway with back-to-back Florida AMA Pro only events, it was evident that Phoenix Racing Yamaha’s Joel Hetrick picked up where he left off last season.View the full article

      Hi my name is Greg and I just acquired a free 2000 yamaha kodiac 400 4x4 with the ultramatic transmission that does not run. I plan to get it going and use it around my property

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?

      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!
