Hey folks,

I upgraded to a Delco-Remy CS144 140 amp internally regulated alternator as the first step towards a dual battery setup. Next I've got a drivers side tray off a 72 gmc c20 camper ready to POR-15 so I can wire in a deep cell, some lights, stereo, and the story goes on and on. Before I do all that, I want to ride over to the Year One Braselton Bash this afternoon!

Before driving 40 miles over to there, I took the blazer out for a spin, drove a few miles, got her up to 65 mph. Once back at home, I found that the (flat not tube) 30 amp fuse between the alternator and the positive terminal post/junction on the inner fender is getting really hot to the touch (but not fried). It still slides in and out of the fuse housing with ease. I never noticed the heat before when I was running a 70 amp unit with external voltage regulator. I'm still using a 12 gauge wire from the alternator.

My questions for anyone that might assist me:

Do I have reason to be concerned? Is it okay for a fuse to be hot to the touch?

Do I need a larger gauge wire from the alternator?

I assume I keep the 30 amp fuse?

Thanks for any feedback you all can provide.
