Trouty56 565 #1 Posted April 14, 2010 Have a look at this picture (not very good, taken with my phone) of the coil on my D180. You can see the resin is melting out the side. It actually dripped on the engine. I figure on buying a new one. What caused this? Just age?? I guess it is 35 years old. Hopefully this is not the result of another problem. The engine runs good but smokes like heck. I am working on pulling the engine and replacing the rings. I saw a post by TT some time ago about a Harley coil and saved the ebay page.

Trouty56 565 #3 Posted April 14, 2010 Rick, I was hoping you'd say "This occurs when......." and then tell me what was wrong. Haha. Oh well, maybe somebody else has seen this happen. Thanks Rick. Share this post Link to post Share on other sites
algrc120man 0 #4 Posted April 14, 2010 is that an onan if it is ihave seen the voltage regulator go bad and send to much to the coil not sure why the coil was affected in this way. the engine was on a pump on a fire engine not a may check your voltage if thats not it make sure there isnt a ground wire problem or the points arent out causing to much resistance or maybe it just gave up due to age :D Share this post Link to post Share on other sites
Save Old Iron 1,563 #5 Posted April 14, 2010 The resin you see seeping out of the coil may in fact be polychlorinated biphenyls (PCBs) check out this website for some cautions as you clean up the spills and dispose of the coil - its nasty stuff - carcinogenic http://www.atsdr.cdc.gov/tfacts17.html#top Share this post Link to post Share on other sites
Trouty56 565 #6 Posted April 14, 2010 This is a Kohler 482 engine. I checked the voltage at the battery a couple times over the winter. I had an ignition switch go out. It was a little over 14 volts. I figured this was ok...maybe not. The points and condenser are getting replaced in the refresh I am getting ready to start. Chuck, thanks for the warning. I read the website you provided. I never gave it much thought because I don't fish much or eat that many fish caught here in the state but there has been warnings about the PCB's in the trout and other fish that are taken as sport.
