It's all about the almighty buck. Vibration, repeated heating and cooling (thermal cycling) are the enemies of electrical devices. Feel comfortable going up to a 15 amp fuse?? What total amperage load does that 10A fuse see?? What type of device is the fuse protecting?? Is there an "inrush" current spike every time?? All fun, annoying stuff..... Is there a time delay "Slow-blow" 10A flat blade version available?? Edited December 27, 2023 by ri702bill 1 Share this post Link to post Share on other sites
peter lena 8,086 #3 Posted December 27, 2023 @ri702bill might try that slow blow fuse , also might separate the . loading , have an identical set up in , another horse , ,no issues , was just out on the road . will experiment with a 15 amp fuse , agree with the , CYCLING , theory , other thing is that it never blows / apart . just a thinning of the connector , is enough for same issue , thanks for the reply , will try related hook ups , thanks , Pete Share this post Link to post Share on other sites
lynnmor 6,802 #4 Posted December 28, 2023 There was a test done on the cheap fuses that showed that they were WAY out of tolerance and wouldn’t blow in time to save the circuit. While I hate to spend the money for the overpriced name brands, I see no other choice. 3 1 Share this post Link to post Share on other sites
Jon Paulsen 282 #5 Posted December 28, 2023 Yep. Nothing worse than junk parts. Especially with safety components like fuses. 2 Share this post Link to post Share on other sites

This video is what I was referring to and should help with understanding the issue. Share this post Link to post Share on other sites
Jon Paulsen 282 #7 Posted December 28, 2023 I was not confused. I just misused an emoticon. 1 Share this post Link to post Share on other sites
