    TKS Ignition system hissing/sucking - not working properly

    Hey FT thanks for the link. Do you know if these fuses are sealed on the bottom? Does it matter if they're open or closed I haven't been able to source mini blade fuses that are closed on the bottom between pins. Do they need to be sealed if inside the waterproof fuse holder? Thanks

    TKS Ignition system hissing/sucking - not working properly

    Update. After replacing the thermostat and wiring up the new diode the TKS system is running good again no more hissing noise after warmed up for 10mins or so. Very happy the issue has been resolved. Thanks again guys. You guys have been very helpful. Now I just need to figure out the 15Amp...

    TKS Ignition system hissing/sucking - not working properly

    I'll be doing the work and running the boat on the driveway. Time to put her to sleep for the winter..... :( This is my only weekend I have before life gets too busy and the days get too cold. Any issues doing all this on the muffs?

    TKS Ignition system hissing/sucking - not working properly

    Hey alldodge, Do we know if temp switch is bad if thermostat not working (engine too cold) does your test work if thermostat still no good or is this test based on thermostat getting engine up to 160. See my last post to FT.

    TKS Ignition system hissing/sucking - not working properly

    Hey FT, yes I realize now my wording was wrong for the diode, alldodge said the same thing, all I knew was that it had no continuity both ways as stated in the post which means open. I just said shorted because it looked burnt inside. Can I edit that post now I can't find a way to do so. Would...

    TKS Ignition system hissing/sucking - not working properly

    Sorry FT you lost me. I haven’t mentioned any damaged wires. I uploaded a pic of the 15Amp fuse that is blown. It has a pink wire and a red wire with purple stripe. Where do these wires come from relate to? Alternator? Previous owner had the starter replaced. Would the starter be part of the...

    TKS Ignition system hissing/sucking - not working properly

    You mean jump the diode plug don’t you. Lol I feel stupid now… Why am I removing the fuse btw? Lol I almost understand this system… stay with me. Here’s a pic of the 15Amp fuse behind engine. Pink wire & red wire with purple stripe.

    TKS Ignition system hissing/sucking - not working properly

    Oh great thank you I will definitely try this. So when you say jumper what do you mean exactly. Point A to point B. Sorry dumb it down a little for me lol. And if the hissing goes away then the fix is new diode and thermostat? Is this what you’re thinking. Sure hope so!! I’ll be so thrilled...

    TKS Ignition system hissing/sucking - not working properly

    No worries. I’m no mechanic and appreciate the help. When I Said in my original post that the diode looks like it shorted I just didn’t have the lingo proper lol. But I did say it had no continuity multiple times and eventually corrected myself with reference to the bulletin and your wiring...

    TKS Ignition system hissing/sucking - not working properly

    The diode is open. will not allow current to pass either direction. I'm leaning towards temp switch... I tested the TKS module it DOES fully extend. I measured it cold and measured it warmed up and measured the passage it goes into and with the amount it extends the passage would be blocked...

    TKS Ignition system hissing/sucking - not working properly

    I don't remember seeing the temp gauge ever reading higher than around 130. Cold lake? lol.. Maybe this is part of the issue. Would this mean possibly thermostat stuck open not letting engine get up to temp? Helm accessory plug? I don't know what this is. Where is this located? Never used any...

    TKS Ignition system hissing/sucking - not working properly

    Yes boat runs fine other than the hissing noise and sometimes hard restart. Usually turns back on second or third try though. Sometimes I increase throttle to get it to go. Ok so the diode having no continuity doesn't prevent power to TKS? OK I will check the temp switch tonight. What about the...

    TKS Ignition system hissing/sucking - not working properly

    This is really helpful alldodge, really appreciate the help here thanks for all the explanation of how the system operates. So like you said, if the 20amp fuse isn’t blown then maybe the only issue here is the diode? Can the diode just fail over time? Or do you think a grounding issue may of...

    TKS Ignition system hissing/sucking - not working properly

    What do you mean temp switch shorting to ground? What if it is not operating properly. It won't feed power to TKS module if not closing at operating temp as per the note in the diagram you provided. This would explain TKS not extending. The TKS DID extend fully I checked/tested it to manual 41...

    TKS Ignition system hissing/sucking - not working properly

    Just looking at the wire diagram some more. The note bottom right says: "If diode shorts engine will continue to run, If diode opens TKS will not shut off extra fuel until temp switch closes." Ok so this sounds like what I'm talking about. Where is this temp sensor located? Part #? I am going...
