Resistance at powerpack terminal

[nordy]

Hi, I've got a 2000 Johnson 30 HP with an engine that died in seaweed und wouldn't start for 1 hour.<br />That's why I checked the ignition coils and the stator, also the ground resistance of the two cables leading from the powerpack to the two ignition coils.<br />The Fluke digital meter measured around 30 MOhm<br />at one terminal, but infinite at the other.<br />That worries me a little bit, because I expect the two power stages in the powerpack to be equal.<br />Can this mean, the powerpack is wrong ?

Re: Resistance at powerpack terminal

what made you check the p/pack and coils, did you have no spark, if so is your eng remote start, key switch elimination test?, check the entire ignition system for a no spark sit. if the engine restarted an hour later, was it just flooded. id check the ign system just to be sure

Re: Resistance at powerpack terminal

Maybe the engine died from overheating, because after holiday I checked the water pump wrong (no tell-tale).<br />Maybe the SLOW-function of the motors was activated.<br />Normally one would expect engine revolution not exceed 2000 rpm but not engine die completely with SLOW activated.<br />I had another accident with the Johnson when I drove into a plastic bag, which had turned around the prop.<br />It resulted in an activated SLOW (2000 rpm), but just for 1 minute or so. Afterwards the motor continued running very well, as mostly before.<br />That's normal and easy to understand.<br />I couldn't believe the overheating theory first and a rest of doubt is still in me because one hour seemed much too long to me for normal SLOW-mode.<br />That's why I checked the electrical components.<br />I thought powerpack could be wrong during the hour.<br />What's Your opinion on the overheating theory ?<br /><br />Greeting from Germany<br />Nordy
