I've watched all kind of videos and this is the only one that tells you what it sounds like if your starter relay is good or bad. Mine is constantly clicking when trying to start. My battery may be too low as it's been sitting for 6 months

Thanks for watching, we are honored you reached out to us. Replacing your relay will likely solve issue. Please keep us posted. 😁👍🧰

How do you close that box again

@@Smokin-kw2hm Thanks for watching, very carefully and with the rubber seal properly positioned. 😁👍🧰

i just replaced my starter relay and put in a brand new fully charged battery. but i am still only getting one click from the relay and no start and all fuses are good. any ideas on what i should try to do next?

[@leobenson4244]

Try jumping solenoid by crossing terminals with a screw driver. If your starter cranks over then it’s something up stream electrically if nothing cranks replace starter.

[@detail4168]

Change your starter there’s no current getting to it

@@leobenson4244Did you resolve this? I am having same issue. Please let me know what fixed it if resolved. TIA.

@@danielwalker66 does it crank when you jump solenoid?

[@stevelange8543]

I keep seeing everywhere that if you only get one click it is the relay with no mention of it potentially ever being the starter. I tried a new relay and still only one click. I have 12v coming from terminal post on relay that goes to starter when I push start button, however, it doesnt even try to turn over, just clicks once. Hooked up a new starter using ski battery to test and starter works. Sounds like its the starter then for sure?

I’m not getting any spark they are new spark plugs. I can’t believe this has happened I haven’t even gotten to ride it once. My luck is the worst

[@IDVDalot]

Question: I changed the relay and now the ski tires to start ( but does not turn over without even using a lanyard. And after I push off on the starter button there is a loud humm that stays on for what feels like a minute. It sounds like its coming from the back of the ski. The battery is at 12. 65 Any ideas of what to do next?

[@DIYwithMichaelBorders]

@@IDVDalot Thanks for watching, any update? Where is your electrical box located…?…rear of hull. We recommend opening electrical box again and double checking that nothing is loose, wet, damaged, or burnt. We also recommend checking the positive and negative cables feeding out of box and connecting to the starter and ground location of engine. Your starter may have parasitic power after engine shut down and is slowly spinning inside… however, not fast, nor powerful enough to engage bendix into engine.

I just bought a Kawasaki 900 it was starting fine and I looked down and seen the oil Kline from the oil pump was off when I went to put it ion they all crumble not sure which line goes to what her well now there’s no start and no spark

[@DIYwithMichaelBorders]

Thanks for watching, any update? Have you been able to find any helpful videos that show a Kawasaki similar to yours? You may need to reference your serial number service manual for exact location and position for each line.

[@Melinda-ul1hq]

@@DIYwithMichaelBorders I’ve watched every video and just stopped and cried. I know it has to be simple because it was starting when I seen the oil lines now it’s just clicks I think the start solenoid is what’s clicking if that’s what u call it I think it is

[@Melinda-ul1hq]

There’s no one around here that works on them and couldn’t find a friend to help if I begged

[@DIYwithMichaelBorders]

@@Melinda-ul1hq Thanks for the reply, we can hopefully help you. The DIY community is the BEST and working on jet skis is something we enjoy. When you attempt to start jet ski, do you hear the starter clicking that is attached to the actual engine or is it indeed coming from the starter relay itself located inside electrical box? If the click is indeed coming from the starter relay, we would start by replacing your starter relay.

[@DIYwithMichaelBorders]

@@Melinda-ul1hq Finding dealers and marinas to work on older Jet skis can be difficult however, we have set out on a mission to fill that gap, and help the entire DIY community with working on their older clastic Jet skis.

Just went for a ride the other day went to start today key is being recognized as it beeps but doesn’t crank. Crossed the solenoid/relay and does crank test voltage at the solenoid came to 12.59v when I press start button voltage fluctuates. I did order a new starter relay so you think that could be my problem?

[@chadvelvick5266]

What could be this problem? I push the start button and the starter engages, the engine turns over for a partial second then the starter drops out. I can release the starter button and when pushed again it does the same thing as many times as you'd wish to try. Removed the battery, charged and reinstalled. No change. Thoughts?

[@chadvelvick5266]

Battery is 2 years old.

[@DIYwithMichaelBorders]

Thanks for watching, that’s no fun. Have you replaced the Starter relay?

[@chadvelvick5266]

@@DIYwithMichaelBorders no I haven't. I pulled the battery again to charge. Gonna have it tested tomorrow first thing. Thanks for replying.

[@DIYwithMichaelBorders]

@@chadvelvick5266 We are happy to help. 2 year old battery should still be good. We are leaning toward the starter relay being intermittently charged during start sequence and because of that, fading out during the start sequence. If you replace relay and issue continues, do you notice or hear any knocking or thumping during startup? If your knock-sensor is detecting a knock or thump during startup, it will cut the power to the starter and shutdown engine. Or… if you have no knocking or thumping during engine start… you might have a faulty knock-sensor that is claiming you have knocking when you don’t…and shutting down the start sequence. Or you have a weak/worn out Starter.

[@markhenke2709]

Hi What if no click at all from the relay... I only get the pump priming sound when put in the DESS key and then again when pressing start/stop each time?

[@DIYwithMichaelBorders]

Thanks for watching, it’s likely that the relay needs to be replaced since you are not getting any response from it.

[@markhenke2709]

@@DIYwithMichaelBorders hi thx can check if the relay is getting power how? I do not see ground wire in the box only red and blue.. can I just ground anywhere?

[@DIYwithMichaelBorders]

@@markhenke2709 Thanks for the reply, you can test continuity of relay however if it’s not clicking as discussed in this video…it will be best to replace it.

[@markhenke2709]

@@DIYwithMichaelBorders ok thx so much so I tried testing it I grounded to the battery and getting power 12.4V to the front terminal of the relay but nothing to the rear terminal even when pressing start/stop!

[@DIYwithMichaelBorders]

@@markhenke2709 Thanks for the update? If you know your starter is good, and it ends up not being your relay causing issue…it’s possible that your start/stop push button is giving you trouble.

[@cariea]

After a long winter I’m trying to get my SeaDoo started up again. My battery is fully charged. When I connected the battery to the jet ski I switched the wires. Oops! But I rectified that now. I’m getting 12 volts at the relay. When I push on the starter button nothing happens not even one click. What should I look at next?

[@DIYwithMichaelBorders]

Thanks for watching Dale. Just to confirm, battery is fully charged?

[@cariea]

@@DIYwithMichaelBorders yes battery is fully charged. Also when I put the key on the key hub it doesn’t make the usual double beep sound.

[@DIYwithMichaelBorders]

@@cariea Awesome, since battery is good and relay has 12v…time to check some fuses. You may have overloaded a fuse or two when crossing power cables. Inside your hull, you will find the fuses. Keep us posted.

[@cariea]

Found the problem. It was a blown 5 amp fuse in the front compartment. Thanks again for your help!

[@DIYwithMichaelBorders]

@@cariea Very cool, and awesome job Dale! Nothing better than a successful DIY project! Who knows how much that would have cost you if you dropped it off at the marina. Again, great job! Keep in touch! 😎👍🧰

I replaced my starter relay and it still not starting what do i do

[@DIYwithMichaelBorders]

Thanks for watching, is it making any clicking sounds? Is the engine turning over and trying to start?

[@pickhimup]

What type of jetski is that

[@DIYwithMichaelBorders]

Thanks for watching, this is a GTX DI.

[@apexsavage2711]

So when I go to start my jet ski it isn’t a clicking noise but I can hear like a girgling noise anyone what it may be ?

[@DIYwithMichaelBorders]

Good morning, thanks for watching. Any update? Gurgling on startup with engine actually firing up is usually due to water inside portions of the engine that it’s not supposed to be in. Example would be water inside combustion chamber…which hopefully is not what’s going on with your engine. Do you see any signs of fuel leaking?

[@apexsavage2711]

@@DIYwithMichaelBorders it doesn’t fire up, which leads me to believe it’s the starter or starter solenoid but it’s also not like a definite clicking sound is there any way I can send you a video of the sound so that you may be able to tell what is it. I think it may be a loose a connection but also there was a tiny bit of water at the bottom of the engine as well it sounds like a week connection on start up but I have a video I would love to send to you of the sound it’s making of you don’t mind! I’m so eager to try and figure out what’s wrong with it! I took it out for two runs at the lake and it ran flawlessly then hopped on it again and nothing making that weird sound I’m talking about

[@DIYwithMichaelBorders]

@@apexsavage2711 Thanks for the follow up, that’s definitely way better than a water logged engine! 😁👍 This is the best way to keep in contact with us. We definitely recommend replacing Starter Relay first to see if it fixes issue. If it doesn’t, Starter replacement is next. Keep us posted. 👍
