If your meter has one look at the screen. Im pretty sure you have a lighting coil.

Power Pack Cd2 No Rpm Limit For Johnson Evinrude Outboard 4 60 Hp 2cyl 85 01 In 2021 Outboard Power Pack Johnson

The charge coil charges up the caps in the CDI pulsars tell it when to discharge not sure on the too high from CDI to ign coil but think if the ign coils do not bleed it down as it should when discharging it might be a problem with ign coils.

How to check cdi on outboard. Second I checked the CDI unit. Here are CDIs troubleshooting pages for most ignition systems. CDI Electronics 353 James Record Rd SW Huntsville AL 35824.

Find your CDI power pack. Yes and if you look there is rectangular connecter from the pulsar coil that feeds into the CDI a triangular connector from the charge coil that feeds into the CDI and a rectangular connecter from the lighting coil that feeds into the rectifierregulator. Watch for a spark and observe its character.

A pulser coil is a switch that sends a trigger signal to the outboards capacitor discharge ignition CDI module. In the mean time I found a website that shows what you should see on every CDI power pack and on which lead you should see it. CDI Ignition Troubleshooting Guide.

Turn on the volt meter. Could be a pulsercould be the CDI or it could still be a fuel issue or a wire connection. When I connect these 136V to the CDI unit they dropped to 40V.

Therefore the only way you can tell whether your CDI has a problem is by confirming that everything else is in the right condition. Turn the motor over one time only either with the recoil starter or the electrical starter. The reason is that there is no particular way of testing the condition of the CDI.

If the engine does not have the converter box installed you may have a CDI Electronics replacement Stator only CDI PN 176-4796K1. Here I have drawn a pretty simple setup which is a two cylinder motor that shares a single coil. First I checked the HV supply in a bike I found it to be 125VAC.

Speed limiting operator warning function. Power Pack Ignition Module for Johnson Evinrude Outboard A power pack or ignition module is the device that controls the timing of ignition functions on all engine cylinders. Use an ohmmeter to measure the electrical resistance of the CDI box in a quantifiable way.

If an upside down horseshoe appears the meter is ready to read OHMS -- resistance. Some power packs also have a SLOW. It was working fine.

Or you can use the test wheel and check out the fuel system and CDI inputs and outputs when its failed. If the coils correct resistance levels fail to meet these specifications youll know that your coil is. 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.

Different vehicles have specified electrical resistance within the coil. Plug em up check voltage from stator check voltage from trigger check voltage coming out of CDI. They are using some sort of aggravating page-turning Flash application for the guide but once you find your ignition system in the index manually go to the page.

Find the model number of your CDI power pack 2. When the fuel pump has a problem spark plugs or coil packs are faulty you would observe similar symptoms. Take care of your CDI.

For an outboard motor turn the meter dial to 200. A good strong spark means the air and fuel mixture in the cylinder will. Turn the multimeter on and switch the power to the DC or Voltage setting.

Under the seat of your motorcycle you will find a connector with a blue and white wire coming straight from the stator and going to the CDI box. Check the ground wires and the electrical connections. The module takes a steady flow of low voltage DC current from the regulator briefly stores it and allows the current to charge and the voltage to build up.

The information is excellent. 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. Check the Resistance Specifications.

Hold the plug wire about 14 inch from the powerhead not over the spark plug. Resistance tests are for verifying that the units are bad after they have failed the inputoutput tests. You are testing resistance not amps or current.

Disconnect the wire leading to CDI and recheck the spark. Copyright 2021 CDI Electronics Inc. So it gets a signal from the CDI to fire when it gets that signal both spark plugs fire simultaneously this particular system is called a waste spark system because only one of the Pistons will actually be on a compression stroke in the sparks fire so the one thats on the compression stroke will actually fire its got fuel in.

Check the DVA and resistance from the Blue wire to engine. Turn the dial on the face of the meter to OHMS not AC or DC voltage. Ensure that you test the side that comes from the stator rather than the side heading to the CDI box.

I rebuilt the circuit same as yours only changed the RC components to fixed values to get 5150 duty cycle and 5775 Hz frequency. Does your C85 have the CDI with a movable timer in it or does it have a movable trigger assy under the flywheel. You can put a box on it for 350 dollars or so.

Connect the peak voltage adapter by plugging its test leads into the positive and negative jacks on the multimeter. One should go to the CDI while the other goes to the ground. On a smaller pull-start outboard motor you find the stop button and follow the two stop switch wires back to the origin.

Plug the multimeter test leads into the voltage adapter. Tighten them to the proper torque with a torque wrench. The output was 136V.

Click the link that says install sheet under the pic of your cdi 5. Exactly tested Mercury and Yamaha outboard CDIs like that all day long. Take a look at your motor and confirm if you like.
