How does an Idle Stabilizer work?

Re: How does an Idle Stabilizer work?

Andy, You can easily remove that temp sensor... And it does measure metal temps... I almost guarantee it!!!! I don't know what you guys are talking about regarding a plastic insert... That thing doesn't need one... It should just be fixed in place with a plate held on with two bolts, the sensor actually threads into the plate... The end of the sensor should rest right up against the cylinder head (underneath the water jacket cover, sealed off from water)... I believe it is recommended that some kind of heat sink compound should be used at the end of the sensor to help in the transfer of heat...<br /><br />Are you sure we are all talking about the same thing? It is brass, and is threaded into the plate with a tan/blue stripe wire connected to it.. The lead is connected to the sensor with a nut on the threads exposed. That lead should go directly to the guage, not the terminal block... However the overheat switch lead does go to the terminal block...

I want to think that you guys are talking about the overheat switch that has the rubber insert around the lead as it goes into the recess that it is located at... Mine has a black wire that is covered with a clear tubing sleave, and it does go to the terminal block...

The link will not work.Go to Merc Parts express http://www.mercurypartsexpress.com/PartsExpress/HomePage/homepage.asp <br />and enter my sr# OC139752, choose the head and reed block.<br />Go there and take a look. You are talking about something different than we have on our motors. Look at item #14, which is the temp sensor and the tan wire goes straight to the gauge, the black wire goes to ground. Item 10 which is the temp sender for overheat. Item #10 goes to the terminal block and is a single wire, it is self ground to the block.

Here's the problem, both the tan (for temp gauge, also called temp sensor) and tan/blu( for alarm, called the temp sender) can be used for the alarm. Because both ground out at overheat temperatures they will both set of the alarm.<br /><br />On most (not all) V6 mercs the overheat switch is on the starboard head and uses a tan/blu wire. On most (not all) the temp sensor is on the port head and uses a tan wire (even sometimes tan/blk in addition.). It is possible they got switched along the way. But to definately test which one is which. First disconnect the switches, sensors, whatevers at the engine. The temp sensor (temp gauge) should show resistance between it and the powerhead ground. The temp switch (overheat alarm) should show an open circuit between it and powerhead ground.<br /><br />-andy

Hi KCLOST,<br /><br />I know what you are goin thru with the temp guage. Mine runs in the red zone most of the time but it doesn't seem to be hurting anything. I've run it for two years without a problem and nothing that you can do with the cooling system will bring the temp down. So forget it and enjoy yourself.
