Allison xb 2003 with a Jay Smith built 225 ProMax 30 HRS on engine assembled about 1 year ago. If you get a reading even very small on any wire the stator is defective and must be changed.

Mercury 225 efi stator test. Put the negative lead on the engines ground and the positive lead on each wires of the stators connector one by one. I have a 2000 Merc 200 EFI that seems to be having a TPS problem. 2002 225 Merc EFI question.

Grn Green WhtGrn WhiteGreen Stripe. Please refer to the lettering in order to follow procedures. On top of that labor might.

I have a 1998 Mercury 225 EFI. The rectifier takes Alternating Current AC from the stator feeds the A and C terminal and converts it to Direct Current DC and outputs the voltage to the B terminal marked with a on both sides. I tested when the engine was cold and found that 5 of the prongs tested good at around 1050 ohms.

Mercury Marine recommends that the switchboxs be replaced in the event of a stator failure. Normal compression psi should be 100 to 110 psi 689 to 758 kPa for 225250 horse- power engines and 80 to 90 psi 551 to 620 kPa for 3 Litre Work engines. Hook a timing light to cylinder 1.

A final test to verify which component is bad is to swap the stator leads from one switch box. You should have a reading of at least 150V or more at both places on all cylinders. You can tell the stator is bad based on the symptoms of the engine.

Set your multimeter to Ohms. To perform the Voltage Output Test you will need a special DVA Meter. The boat would not even plain.

Share Link to this post Email Bullet20dc PM Bullet20dc. So typically it would be about 140 for the stator and 110 for the switch box. Usually there is a load associated with the test and you may have to fabricate an appropriate load.

The Unit can be used to test points preamp triggers Mercury Outboard battery CD triggers hall effect triggers Alternator driven Ignition triggers and can be used to check injection Pulse from Mercury Outboard EFI modules. Connect Negative -- Meter Lead To. Spec calls for 120-160 volts at 1000rpm.

Inspect powerhead for leaking seals gaskets or brokendisconnected throttle spark linkages. CAPACITOR DISCHARGE MODULE Connect Positive Meter Lead To. You can know you have a bad stator by looking at it.

Mercury Marine Parts for Mercury Marine 225 HP 30L EFI Flywheel Stator Revise Search. This is how to test and diagnose an outboard stator. Disconnect stator leads from switchbox.

Usually ships within 10 days. If a new regulator-rectifier is needed that adds about 72. The tests involve touching the ground and the touching the posts.

To perform the Ohms Test you will need a good ohm meter. You shouldnt get a reading at all. If you have ignition problems or your battery doesnt charge it could be your stator.

Either its not firing on a cylinder or two see above or the TPS is shot. Did he leave fuel in there all winter with no stabil blue in it. You can make a dynamic test of a stator coil in a permanent magnet alternator by measuring the alternating-current voltage that is produced by the coil when the permanent magnet alternator is rotated.

I bought the boat in 2001later that year it had a problem taking off. Or you see it. Long story short I lost some performance and holeshot and decided to check my stator.

Mercury 225 efi 1998 fires all plugs when test w spark tester. Have him check the rail pressure if fuel is getting there then he probably needs to pull the rail and injectors. This is because a bad stator can weaken or ruin a good switchbox.

Testing the stator only requires an ohmmeter you do not need to remove the flywheel. Let it idle until it comes up to operating temp. Try to start and engine fires at first then looses all - Answered by a verified Marine Mechanic We use cookies to give you the best possible experience on our website.

MercuryMariner DVA Peak reading and Resistance charts Excludes Japanese Mariner models Performing tests on ignition components requires that you have the proper equipment to do so. This test applies to all type stators used on alternators in outboards motorc.

Stator high speed test is NOT within spec. Though it wont be a clear and cut situation. With the spark gap tester connected to each of the spark plug leads set the Spark Gap Tester to 7 16 11mm.

Engine should be cold resistance increases with temperature. When you pushed the throttle all the way the engine would only go about 1000 rpms or so. One briefly hit 850 ohms and rose to 1 signalling an open circuit.

Start the engine on the flush tool or in the water. If the stator is covered in salt and corrosion. Ground Pin A or Black test harness lead White C or White test harness lead R x 100 1250 100 Ohms Green D or Green test harness lead Ground Pin A or Black.

All Models 225 HP 30L EFI 0G129222 - 0G760299 USA Flywheel Stator. But if this is typical of a good running 25 merc EFI then so be it. If the reading is low on one bank and the stator voltage is good the switch box is likely bad.

This is the quicke. A break through by CDIRAPAIR 511-9710 allows you to test most Mercury Outboard Mariner Chrysler triggers and OMCs Quick Start timer bases on the engine. All Models 225 HP 30L EFI 0G129222 - 0G760299 USA Flywheel Stator.

I followed the instructions for checking the stator by testing each prong on the plug to ground. You will need to test the stator and well cover that in a second. I took it to a Merc dealer and he found that the TPS switch was out of adjustment.

Do Not connect the test harness plug to the statortrigger engine wire harness. Disconnect the yellow leads to the rectifier. This chart assumes you have the adequate testing equipment to diagnose ignition problems.

Can be tested on the motor with a Spark Gap Tester. He adjusted it and it seemed to work good for the rest. Remove all spark plugs and DISCONNECT THE ECUACU.

At cranking speed each coil should be able to produce a strong blue spark across the gap on every revolution. Specifications are from a manual that only goes up to 1990. The video shows how to test a stator an outboard Mercury Force 40 HP or 50 HP.

It is often the case that the old switchboxs fail shortly after a new stator has been installed. To test if the TPS is working correctly do this.
