Slow intermittent beep (one beep every 30-40 seconds) - low oil Is that normal behavior?ĭ.boat gave me this info earlier that i did not know: When I disconnect the tan wire that leads to the temp sensor the alarm quits with the key on and engine off.īefore this all happened, I would get a quick chirp tone each time I turned the key on at start up. When cool, the switch should read open to ground, no continuity. If you get a steady alarm, the switch is bad. If no alarm, short the wiring harness side of the tan wire to a good engine ground, you should get a steady alarm. If alarm still sounds with the key on, start hunting for a short to ground in the tan wire to the horn. This is a black rubber connector near the big red connector. If the alarm is sounding steady, also disconnect the plug in the wiring from the VRO pump. With the key on, engine off, there should be no alarm. Simple wiring test is to unplug the tan wire from the switch (upper left of cylinder head), the connector is 4-5 in. You said you have a steady stream from the telltale which does indicate the water pump and t-stat are working. Steady on is overheating, bad temp switch (sensor), or shorted wire. We need to know which alarm you are hearing, steady on, slow beep, or fast beep. The closest marine parts store is about an hour away from my boat so I'm trying to show up with necessary parts. I'm picking up a new thermostat today and gaskets and will replace them on Friday when I head up north to my cottage.ĭo you think I should replace the temperature sensor too? Is it possible a hot engine can damage that? So I was trying to solve the wrong problem if it wasn't an oil issue. I'm thinking that rebuilding carbs should take care of that issue as long as I have good compression.
It did seem to run smoother but still had a flooding issue. I will say that the seafoam caused lots of smoking while I first started running the engine and I did burn through a tank of gas in the week before the alarm went off. I've been reading alot on that topic here. He was adament that the motor should be converted to a pre-mix set up instead of keeping the VRO. Okay I forgot to "say" that the seafoam idea and that the alarm being VRO trouble came from a gentleman down the lake who also owns a Johnson 40. I plan to test compression this weekend.Īny thoughts? I'm tempted to just buy new thermostat and water pump kit and just replace them, but I really want to know what the problem is and fix that. I didn't have all my tools with me so I have not done a compression test, but it was running before this. I get plenty of water out of the tatle tale hose when it runs and when we limped in. Now I'm thinking its a thermostat or sensor issue.
#TATTLETALE SMOKE DETECTOR MANUAL#
I bought a manual and did some reading and thought it was a VRO problem, but I get plenty of smoke at start up and the plugs seem to be oily when I pull them so I'm not sure that's true. The lake level is low and there are weeds, but I was careful to avoid them and I was getting water out of the tatle tale. I limped back to my dock and now after trying several things I'm turning to you all. Last week while cruising slowly the horn in the controls came on first with a few beeps then as a steady tone. I plan to rebuild the carbs this winter as he was not into preventative maint. It ran for him and with the exception of some flooding issues at warm start-up, that sea foam seemed to help with, it was working decently. I bought a 89 Johnson 40 HP VRO with a 20 ft pontoon attatched to it from a guy down the lake from my cottage. Okay I'm new to this forum but have been reading the posts for the last 2-3 weeks.
