TB 302 and 30A spool gun problems

Just an idea from a problem I had a few years ago with similar symptoms. Here's a copy of my old post.

Looks like 7018 downhill.

Which I'm pretty sure it is supposed to be....

Just a follow up.

I think I found the problem. ...

That will be my project for the week end. Thanks a lot....

I found it in the parts manual. It's listed as 10 amp, Would there be any problem replacing it with a fuse? Where I live no one will have a breaker like that.

Thanks for the help....

Checked voltage on A and K and A and G. Nothing there. Tried the breaker and it appears that it won't reset even with the machine not running, can feel it try to click but it wont catch, so now try to find a breaker or replace with a fuse. Eyes not as good as they used to be but I believe it is a 10...

Same here I love mine and was going to replace it a couple of years back just because it is getting high in hours and would have liked to be back in warranty again but not now, just have to take good care of her and hope she lasts....

[shortarc]

Yes same here. Someone needs to remind them of the old saying "if it ain't broke don't fix it". Before all of the updates and redesigns it was good but some just don't learn. Kinda like dropping the Trailblazer 302, I have one and was going to replace it a year ago just because it was getting...

This was probably done by the same engineer that decided when they brought out the TB 325 that the AC capability was no longer needed.
