95 Wrangler 4.0 5 Speed Blew my 30 amp fuse yesterday for the Fuel Control ECU. Replaced fuse and everything worked fine around town until I hit the highway where once again the fuse blew. Tossed in another fuse so I could limp home and it blew immediately. Have spent the day trying to figure out whats causing this. Aug 09, 2019 · Hey guys, my Hustler Z zero turn just started blowing the 10 amp pto fuse. It starts blowing it after about 15 or 20 mins of mowing, if you let it cool down for 5 mins or so it will go for a couple mins then blow again. Odd thing to me is, I put an amp meter in the fuse socket and it never gets above about 5.8 amps when the fuse blows. Jan 23, 2011 · 3 amp fuse keeps blowing on lamp? I have a 9 arm floor standing candelabra lamp which came with a 13 amp plug and was fitted with a 3 amp fuse. So I switched it on and about 10 minutes later the fuse blew.
