Power Pack Most Likely?

Well, I think I have narrowed this down to the power pack. I went to radio shack, bought and built a load tester out of a 10-ohm-watt resistor. Cranked the four primary leads coming off the power pack. I had a freshly charged batt. and I was using the a.c. volt scale. I basically got no voltage from any of the primary wires. I checked each one twice. Made sure I was secured to a good ground.

Prior to this I checked the charge coil and power coil. Charge coil resistance was 1050ohms. spec'd out good. Next I did a crank test output on charge coil and got 160 volts. I am using a FLUKE 77 dvom. the volts are a little low,should be 250vac No voltage leaking to ground

Power coil resistance was 52ohms. spec'd out good. Next I did a crank test output on power coil. Got 27vac. the volts are a little low, should be 45-65vac Again no voltage leaking to ground.

So as near as I can see. Does this indicate a bad POWER PACK? Also with my machine, (Johnson fast strke 115h.p. 1998 60degree looper.) can I check the rectifier/regulator?

Thanks again

Re: Power Pack Most Likely?

I think you should not start more than one thread for the same problem. If you stick to one thread it is much easier for other members to follow what you are doing and what you have done, not to mension what the original problem was.:confused:

Sorry about that, not that schooled on these forums and such

Re: Power Pack Most Likely?

It's just that you kinda lost me with what you are doing because I have nothing to refer back to.

If YOU want to post to your thread but can't find it because it has been buried by a bunch of other threads, there is a box at the right upper corner of the page that says, "Welcome, Crispy". A few lines below that there is a link that says, "My Replies". If you click on that link it will show you a list of all the threads you have ever posted to with the most recent at the top.

Gottcha,
now how might I get a response? I detailed the results on one of these posts. I will copy my diagnostic reslults here again. I just would like to know if I am in the ball park.

www.outboardbooks.com

the manual has all the tests and its just a logical process to zero in.
The factory manual is reallllly good.!

The other part of the equation is the optical sensor, most times its not a bad idea to change it when the pack is switched, the optical sensor is a lot cheaper than the older trigger style. Something like $65.

Also, that load tester doesn't sound right, to make a direct voltage adapter you also need a capacitor and a diode in the circuit. I made one for $15 from ratshack parts. Very simple.
Heres a circuit diagram by BHile.

Also, see this troubleshootin page by Bill Kelly, very good.
http://www.maxrules.com/fixomcoisignition.html

Check the kill lanyard and key-switch position.

Verify the engine rotation (The engine needs to be turning in a clockwise direction).

Check the power pack and ignition coil ground wires for corrosion and tightness.

Connect a spark gap tester to all cylinders.

Disconnect the boat side harness and connect a remote starter unit. Check for spark. If the engine has spark, check the boat side harness's black/yellow wire for shorts to ground.

Disconnect the 5-pin connector on the port side of the power pack and see if the spark returns. If it does, use the fluke meter set to ohms and see if the black/yellow wires are shorted to engine ground.

Check the battery voltage on the yellow/red striped wire while cranking the engine. If below 11 volts, charge the battery or check all battery cables.

Remove the sensor wheel and check for damage, especially where the top slots are located. Sometimes the wheels will break out where the windows overlap.

Check the sensor eyes for dirt, grease and the like. If you need to clean it, use denatured alcohol and a Q-tip. Do not use any other cleaning agent because damage to the optical lens will occur.

Disconnect the voltage regulator/rectifier and retest. If the engine now has spark, replace the regulator/rectifier.

Using the piercing probes, check the resistance and DVA voltage on the 6-pin stator connector while connected as follows:

RED LEAD TO: BLACK LEAD TO: RESISTANCE DVA READING
Orange Orange/Black 50-60 OHMS 12V or more
Brown Brown/Yellow 450-600 OHMS 150V or more
Brown/White Brown/Black 450-600 OHMS 150V or more

Re: Power Pack Most Likely?

First off, I apologize for running two separate threads. I will stick to this one. I made one more test on the power pack this morning. I did not get ANY voltage on any of the four primary wires coming from power pack to coils. I was using the dvom set on AC. I also had my homemade load tester in place. Yesterday when talking with Tech. at a local service shop he was surprised that there wasn't any reading on any of the wires.

The zero value readings to me would indicate that the power pack is opened. I don't even begin to understand what the individual components are inside this pack?

I am going to order a power pack. I see that Iboats do not have any in stock. Anyone have any recommondations as to where to order this pack from.
