Re: testing powerpacks

Basically ,you troubleshoot down to the the powerpack by confirming that everything else is working via a DVA meter.This is on a modern CDI ignition system. Battery CD is a whole different ballgame.What do you have?

Re: testing powerpacks

Hello again Tex,<br />I don't know of any test that can be preformed on a power pack, I've worked on mainly OMC products for over 17 years and have taught a marine service class for over 4 years. You can test the the inputs and the outputs,so if you have the proper inputs, but no output then you can assume that the pack is bad. If there is no imputs then the problem is under the flywheel.<br />Coming out from under the flywheel on both sides there are charge coil outputs these will be brown and brown with a yellow stripe.If you disconnect this from the plug-in on the power pack and plug in your AC multimeter to those two wires that go back under the flywheel, then have someone crank the engine over the meter should read somewhere between 177 & 212 volts this can be considered a good reading. The next step is make sure these wires arn't grounded, take one of the meter leads out and ground this lead, have someone crank the engine over again you shouldn't get any reading, do the same with the remaining wire again no reading. You have just checked one of the imputs to the pack. If you do this let me know and I'll lead you through the sensor imputs test.<br />Hope this helps
