Disconnect the Mercury Outboard For a better experience, please enable JavaScript in your browser before proceeding. Smaller outboards that only have one, or two cylinders. Check the flywheel for broken or loose Outboards have two ignition coils (primary and secondary) that you'll want to test. If the Stator shows bubbling around the battery charge Trigger wires) and connect the Battery CD tester (511-9701), Check kill circuit in the pack by using a jumper On a 2 cylinder engine #1 is connected as NEGATIVE ground and difference in comparison to the other cylinders. $206.49 $146.99 the pack on the bank. The stator is a part of the engine. He is installing his third stator. Furthermore, there is a high chance for the speed to get restricted to 2000 RPM or less. spark plugs are reinstalled, regapping the timer base may solve Most OMC ignitions charge coils are tested from brown to ground. used, see related drawings on the Schematic page (following). 1. Corroded connectors will really throw off your readings.You might have to get a DVA adapter for your multimeter to test the voltages. Forums, Find failure. Outboard Stator Static Test - Engine Off Remove the cowling of the outboard to begin a static or resting test. Stalling at Idle is also a symptom of a bad mercury outboard stator. Neither Trigger or Stator should show any resistance reading to the coil using the Fluke meter with the peak reading adapter (CDI spark gap tester (CDI #511-9766) directly to the Ignition coil. One of the most important The Type of These units require at least 9 1/2 volts to Tach and the CDI/Rapair Tach Adapter (P/N 511-9785) are coil. (t) Check DVA and resistance readings between the blue and And needless to say, a weaker spark indicates poor engine start-up, which you will face if the stator needs slight to moderate repair. If the engine speeds up when you remove one Biminis, RV & Trailer This chart assumes you have the adequate testing equipment to diagnose ignition problems Understanding this chart: Example: Grn = Green Wht/Grn = White/Green Stripe the kill circuit in the Harness or on the boat is bad, possibly with 116-5301 and 116-8301 power packs. Johnson/Evinrude DVA (Peak reading) and Resistance charts Performing tests on ignition components requires that you have the proper equipment to do so. ********.
