Blown fuse-rebuilt 1991 100Hp. johnson

Recommended Posts

About halfway through our fishing trip last week end, my rebuilt blew the 20 amp inline fuse on the motor. It was after we checked on the starter not engaging and the cowling barely fits over the motor. We may have scraped some wires, couldn't see any loose wires, where do I start looking? When I put a new fuse in, it will start, run but blows the fuse again. The T&T is wired through it also, so that goes out and will blow the fuse. Help!!!!

I would start at the battery cables and follow your way until you find a rubbed / pinched wire. I would start with the thicker cables and go from there.

If you can isolate when it does it (only when you hit the trim and tilt, or only when it's running) that should reduce the amount of time you'll have to spend looking.

Wouldnt the hot cable if it were frayed or grounded arch all the time when it hits metal? If you are hitting the key and flows enough to start but then kicks the breaker i would suspect the trigger wire or starter solenoid. How about replacing with a reset type breaker or inline fuse so you dont have to keep replacing them? good theft deturnant if you think about it but pain in butt when wanting to fish.

Since it doesnt blow while cranking, I'd look at the tnt.

While the engine is not running, cycle the tnt several times to isolate the problem as M_M suggested.

    • Heavy rains across northwestern Wisconsin last weekend and early this week have flooded some roads and caused washouts on some highways, roads, state parks, forests and trails. According to the National Weather Service the area has received 7 to 12 inches of rain from Friday through Monday.Several park system property or portions of properties are closed due flooding. Amnicon Falls State Park, closed temporarily but has reopened, though some roads, trails and observation areas remain closed. Pattison State Park is open for camping only; all trails, observation areas, picnic and day-use areas are closed. There are washouts on the dam that forms Interfalls Lake and Highway 35 over the dam is closed. A campground and horse trail are closed at Governor Knowles State Forest and the day use areas along the river at Interstate Park are underwater.Water was roaring over Little Manitou Falls at Pattison State Park.Photo credit: Gervase ThompsonAll rivers in the region are running extremely high. The falls at both Amnicon and Pattison are roaring, but road closures mean observing the falls now is challenging. The Bois Brule and Flambeau rivers are high enough that some canoe launches and campsites are underwater. The water is making its way downstream and the Lower Wisconsin River is running very high with all sandbars submerged and canoeing and kayaking not recommended. The river is expected to crest Muscoda this weekend at 40,000 cubic feet per second. .
    • I'm still going to smoke this fatty while camping this weekend whether Leech likes it or not.....😋       See you fellers on Monday........
    • Rick didn't like all the "My Grills bigger and better then yours" posts!  😅
    • We switched to a new server. Had a glitch in our dB that lost a couple days of posts.
    • I ripped a hole in one of my favorite pairs of fishing shorts just need a decent sized patch to cover her up
    • I am not sure what happened either but we lost all of the posts last couple days not just this thread. And it looks like the same thing happened over on FM site as well. I know the site was down last night while I tried look at it.
    • We had no problems but only brought 10 extra gallons over.  We fished 5 days, pretty much running wherever we wanted and ended with 7 gallons remaining in the boat.  So, we burned 30 gallons of fuel in a 1785 Lund with 90 hp Mercury 4 stroke.   I thought that was pretty good!
    • Seems to me that we are missing an entire page from this thread that was here yesterday.... what gives?
