New Oil Warning Module issues

[Jonezin]

Hey I just got a new Oil Warning Module, my issue is on the box 41470A25
but on the module itself is has 41470A22. Are these one in the same or did someone make a mistake some where along the line. I don't want to put it on until I know for sure, you know how they are about electric parts.

Is there a flying chance you could let us know what engine you are working on?

1988 Mercury135 V6 Marathon 2 Litre XD 0A904646 THRU 0C100860
How about that, i've been looking and called a few people that 41470A22 dont esist theres nothing to cross refrence it to. But there is a 4 digit number on the box and part "0737" does this mean anything to anybody.

Re: New Oil Warning Module issues

The AXX on a part usually indicates the version/series of a part. That module has been updated a bunch over the years, it started out as a A11 and is now a A27, so it will work. The Merc switchboxes are the same way, started as a A1 and now a A12

Re: New Oil Warning Module issues

Thank You sir..... I will slap it on in the morning and let you guys know. I was getting kinda pissed beacuse this is the second one. The first was when I had it rebuilt had it tested toast. And these damn things are not cheap. If this one goes I'm going to just by-pass it and mix my gas.

Re: New Oil Warning Module issues

Before replacing this costly module, you tested the oil tank sensor with the tank empty and sensor still attached to the tank to be sure there's no continuity between the two blue wires going to the module, right? Cause it's something frequent to see a fallen magnet or a bad cap on thoses tank.

And if you don't mind, why did you say it's toasted? You know that it could also be activated by the overheat sensor and the oil pump rotational sensor

Simple test procedure for the module:
disconnect both sensors -? no sound -? OK
reconnect sensors one at time

Re: New Oil Warning Module issues

Well, no. i took it off and took it to tech to bench test it. But there is a brand new on just in case it was bad to.

Re: New Oil Warning Module issues

Sorry, but something doesn't seems right.
1- you parts guy wasn't able to cross-reference a simple part (it's not even a cross-reference, it's only a version number...)
2- you said when you had the engine rebuilt it tested toast
3- you took it to the ?tech? to ?bench test? it
4- you got a new one ?just in case?

Looks to me like someone's making a few bucks by throwing parts.

Please simply do the very basic test procedure highlighted above and i bet your module will be ok.

What was the problem initially? A non-stop intermittent BEEP or a steady one? Most of the time, the problem is with the intermittent one (low oil) and was caused by a fallen magnet inside the tank rather than a bad sensor.

Re: New Oil Warning Module issues

I'm sorry eevrything is bleeding together.

1. The marnia repair shop couldnt cross refrence the number, is why I do alot of my own repairs we only have one shop.
2. After the motor was rebuilt a year later the modual tested toast
3.I took the one I replaced to a tech from work to test it.
4. I got a new cap. didnt replace it when I rebuilt the motor.

Sorry if I confused you I do that sometimes...

Re: New Oil Warning Module issues

No problem (i'm easy to confuse: english isn't my first language, i'm french speaking...)

So what was the problem that let you think you module was bad, other than ?it tested bad?, did it continually beep?

(for cross referencing parts, the best, user-frendly place is http://www.ishopmarine.com. On the right column, you choose ?Mercury store? then you go on with your model/hp/serial until you reach the parts diagrams. From there, when you choose an higlighted part number, a pop-up window appear listing all the available parts: the Merc OEM and, if they exist, the corresponding ones from CDI, Sierra, Malory, etc. Personnaly, I suggest you to browse throught parts listing on www.ishopmarine.com then, when you're ready to order, go to www.iboats.com )

Re: New Oil Warning Module issues

it beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeped all the time, I unhook it, it would stop. I ran mixed gas just in case

Re: New Oil Warning Module issues

Ok I'm officially stumped. Hooked up the new one and its still f@%king beeping................
I'm thinking maybe the temp is doing something I will unhook everything tomorrow and just hook the modual.

Re: New Oil Warning Module issues

Steady beep is the temp alarm. Could be 3 thing:
1- engine is overheating
2- sensor is bad
3- module is bad

If you could put and let your hand on the block, it isn't overheating.

Disconnect overheat sensor.
If it stop beeping, sensor is bad.
If it continue beeping with sensor disconnected, it's the module.

Re: New Oil Warning Module issues

It's not over heating at all, in fact I have the gas turned off . So im just spinning the motor a few times.
Ok this is what happens.
1. Turn key on get get 3 beeps (systeam OK)
2. spin the motor a few times, beepping starts. Let go of key still beepping.
3. Turn key off, them back on, 3 Beeps again.

I have temp sensor and a temp sender. One is mounted in the head and one on the side.
The one in the head met up with the brn/blue wire from the modual.
Disconnect that one Right?

Brand new rotation sensor in all ready, new cap sensor, new oil pump. I would pull it all but i'm in to deep now. LOL.....

To top it all off,New Oil Warning Module, thats what I just put in.

Yes. If it doesn't beep, the sensor is bad.

Re: New Oil Warning Module issues

Ok, did some checking with it today this what I have found.
1.The overheat sensor wire is just fried, (old and worn out) so I disconnected. will replace as soon as I find the part #.
2.Still beeping, so I disconnected the oil tank on motor, still beeping.
3. Reconnect oil tank, disconnected rotation sensor. binggo banggo, no beepping.
4.Run to part house get a new one hook it up, guess what?.... Beep beep beep etc........

What the F@#K........................

Re: New Oil Warning Module issues

Your oil pump is not spinning at the same speed as engine, it gets its refrence from switchbox. Sounds like oil gears has stripped or if you had pump and bushing out the magnet is upside doen in bushing.

Re: New Oil Warning Module issues

Couple of items.
1. The alarm circuit is pulled to ground to sound. The oil alert, heat sensor. or a mouse bite in the harness can ground it.
2. The maintenance manual has an easy to follow procedure to check out the oil alert and temp alarm system.
3. The sequence of vents in this thread doesn't always make sense. You are overlooking a fault, or even putting one in.
4. Systematic trouble shooting is a lot cheaper and faster than guessing.

hope it helps

Re: New Oil Warning Module issues

Does the driveshaft for the sensor turn when you crank the engine ??? If not the plastic gear on the crankshaft is stripped out

Re: New Oil Warning Module issues

My ohm meter seem to have gone MIA, so i checked it the best way I could and there is pretty much 3 areas that could be effecting it. I'll pull out the shaft this weekend and report back. Thanks for all the help...
