89 Evinrude 150 no spark

[Pop-R]

I'm thinking my power pack has gone bad, does anyone know if they can be tested to know before I spend that kind of money on a guess?

That has the butteryfly pack, Have you checked your kill switch? Put hose on it and remove the cowling. There is a black and yellow wire comming off the pack. Remove it and see if it has spark. If so it is something in the harness, switch,or kill switch. If not it needs to be tested further.

Yes,
they can be tested. It takes a special tool to measure the voltage from the stator,timer base, and the output of the pack.

Thanks James, Okay this is crazy while looking for a black and yellow wire. I took the power pack off we checked and each coil was getting around twelve votes. Then all the coils on the passenger side started fireing. I tried switching out coils and wires. I then started testing and the top cylinder on the drivers side started fireing. The bottom two won't fire I tried trading out coils no difference. Any Ideas? My Coil Pack has four conectors and the coil feeds for both sides coming out of the back. It shaped like a T with ears for bolts at the top on each side.

You have to have a special tool to check voltage on this system. A regular volt meter will not work right. All you have to do to check the kill circuit is unplug the big red plug and jump the solenoid and see if all cylinders are firing. How are you checking spark? Holding the plug against the block sometimes don't work very well. Usally it is a bad pack on these engines when you loose fire but i Have seen alot of timer bases go bad. But be sure to check kill cicuit.

It is firing now on 4 of the 6 cylinders so it won't be the kill switch would it, and I was just hold a plug a aginst the block. But it is strong. I was also checking the voltage at the coils with a volt meter and it was jumping all the way up to 17 volts.

I have seen kill circuits do some wierd stuff so i would check it. But more than likely its a pack or timer base but without checking it with the right meter its just guessing. We use what it called a cd-77 to test ignition systems. Its the only way u can check it to be sure.

On that year it is yellow and black in the one connector going to the harness.

You should not have 12 volts at each coil. If you do you have a problem. This system is altenator driven ignition. The coils work off of a/c volts. They will read around 130 to 150V A/C. Could still be a power pack or timer module. Because the voltage fluctuates very rapidly it takes a DVA to satbilize the voltage so a meter can read it.

Your pack is this one

I have all the special tools, adapters, and the charts to check it. I have replaced more powerpacks on those than anything. Like spam said, testing is the only way to correctly identify the issue. </p>

</p>

If you have a good Meter I can post how to make your own DVA for around $5. I have $90 in mine. </p>

</p>

This is the chart on where voltage is suppose to be where. It take a DVA adapter to be able to read the voltages. Hope this helps</p>

Thanks guys, James I will show my step-father the info listed he is pretty good on electrical and will probably know more about what you've listed.

Like We said.....It takes a special tool to measure these voltages. You can't just use a multimeter to check them.

 

[wrechin2]

This is what you will need to build to make your own DVA to test these voltages......

 

[wrechin2]

The OMC DVA is the specific voltages for your engine. The other on is a general as most V-6 engines use the same voltages. Hope this helps!!!!!!!! I have never built one of these but want to one day. The parts needed are suppose to be around $5. I bought mine from CDI. Mine is this one. Notice it states the reading will be close to the stevens 77...Of course I bought mine from one of my suppliers not here. This link is to show you what it is.
