Sometimes the fuse can develop an invisible hairline crack that causes power drop when hot or bumped a certain way. To test the unit remove the fuse and replace temporarily with a 12 GA piece of solid copper household wire and test. The fuses are cheap enough if still available.
Final update guys. The part Fernando listed in thread didn't work for me either. But the link below from amazon listing did. It's was 111 dollars and worked on my swapped 617a without a pre glow temp sensor. huco 13 2036 Huco Preglow Time Relay https://www.amazon.com/dp/B004JQBGR2/re ... TCbXTA0YQ2
Not sure why this part worked in particular and all the others didn't but I get a good 20 second pre glow with this unit. Thanks for the help everyone.
