Great video. And thanks for the wiring diagrams!!!

Does this temperature switch contact the cooling water or does it contact the engine block ?

Very informative videos. Thank you

I realize this video is several years old, but hoping someone can suggest a fix for a warning alarm issue I am dealing with. The issue is the volume on the buzzer is very low for one engine and normal volume for the other side. Apparently both engines are connected to the same alarm/buzzer. The volume is so low I cannot hear it when the console is closed. The alarm volume is also low anytime the key is put in the ON position so it's not only at overheat. I have tried researching this issue online with no luck. I'm thinking of swapping out the ignitions as the alarm is part of this. Thanks in advance for any help.

Thank you!

Thank you for the good instructional video. I do have a question that I think you may be able to help me with. After watching your video, I think my issue is the temperature sensor itself. But here’s what’s going on…

Thank you ! Great video!!!!!! will you do one for a fused breaker system

I have a 99 Johnson J115PLEEM and the buzzer keeps going off, even when cold start. Just stays on, constant beep. Thoughts?

[@Supanova70]

Quest i already have 2 buzzers 1 for each inboard. I want to wire a warning 12v led to the 2 terminal buzzer. It has 12v across both term. key off when turned on buzzer sound and oil pressure switch activates the buzzer until started then turn to ground on 1 term.. I wired the light between the 2 term and works great. Should i use a diode or inline fuse for 1 side of the 2 term buzzer? These are tiny leds.

Is there anyway of hooking a temperature Gauge to the sensor? I hate not knowing the temperature while I'm running the engine.. By the way, I have a Honda bf130hp. Thanks..

So. If my temp sensor goes off after 5 mins how can I diagnose if its not working. Obviously checked all cooling system. Does magnet in sensor go bad? Would the ground wire be damaged?

[@eversky1365]

When I turn my key to on the buzzer is in constant alarm. There was no grounding wire on the buzzer as your provided diagram shows and I am worried my accessory wire and temp sensor wire are installed backwards. If they were, would this cause the constant alarm?

[@raymedorio1930]

Hey

[@marcaustin]

Does anyone know what temperature trips the alarm?? Like 160 or 185 degrees?? tks

[@txiong842]

Help!! After installing my temp gauge the needles stays a bit pass half way even over night!!! “1995 evrinrude 50hp 3cyl”

[@nicollemarticello3488]

I suspect I have a bad sensor since my 40 HP evinrude gives me the horn after a short period of operating at high RPMs. I disconnected this sensor and I still got the horn at high RPMs. Is there a common miswiring that would cause this or something else?

[@mother-fng-bonswa3612]

why are these buzzers so expansive, its nothing but a buzzer. i can make a buzzer and led for not even one dollar, that does the same job.
