200 GasGas 0 #1 Posted July 28, 2019 Howdy, people. I need direction ! My 416-8 is blowing her 30amp fuse. She'll start and idle normally. When I advance her transmission lever, she'll proceed forward for about 5-10 yards, then blow that 30amp fuse. I am a "professional" at making simple problems complex. Before I dig into my 416-8, could you fellows share your knowledge with me so as I may go straight to the crux of my electrical problem? Thank you in advance.

pfrederi 18,566 #2 Posted July 28, 2019 Welcome to red square. Going to need some more info. Over the years 416-8 came with three different engines. K series Kohler Magnum Kohler and Onan. Not sure what you mean about advancing her transmission lever.. Share this post Link to post Share on other sites
squonk 43,452 #3 Posted July 28, 2019 also need year. The only 30 amp fuse I see goes to the charging circuit. Need to check voltage regulator connections for grass dirt buildup causing a short. 1 Share this post Link to post Share on other sites
lynnmor 7,727 #4 Posted July 28, 2019 Download the demystification guide Check the battery, a bad one can overload the charging circuit and blow that fuse. Check the voltage at the battery as it starts and see if it climbs above 14.5 volts till the fuse blows. 1 Share this post Link to post Share on other sites

Transmission lever: The arm to the right of the steering wheel. Push it forward and the 416 moves forward. Push it down and pull it to the rear and the 416 moves in reverse.

Need to check voltage regulator connections for grass dirt buildup causing a short. Year: 1996. Question; The voltage regulator .......... what does it look like and where is it located ? One more question; My 416 has 776 hours on the hour meter. I change it's oil and filter each spring. From your WH experience, can I expect her to reach the 2000 hour mark ?

You have a 416-H (Hydro not a gear drive 416-8) Share this post Link to post Share on other sites
953 nut 59,333 #9 Posted July 30, 2019 While searching out a blown fuse problem you can remove the fuse and put a test light in place of the fuse, without a load the light will not be on, if there is a load (including a short to ground) the light will come on. Looking at pages 402 and 403 of this wiring diagram download the 30 amp fuse feeds Starter Solenoid through the Starter Relay and connects the battery to the charging regulator/rectifier. The problem will be in the wiring to these devices. If you remove the 25 amp fuse (engine not running) and inspect and slowly move each wire in the flow path you will probably find a wire that is shorting out to ground. Most of these components are under the battery so some corrosion could also be causing the problem. Let us know what you find. Share this post Link to post Share on other sites
