I just got my 3G conversion done and I fired it up for a test. I turned on most of my electronics (2 fans, fuel injection, headlights, arb valve) to give it a test. My original alternator had me down to 11 volts since I added the 2nd fan. All was going good for about a minute, then my main fuse blew. It didn't just blow.. The plastic was slightly melted.
All my wiring is custom since I've been buggyfied. I've got a main wire going from the battery to fusebox A. It goes thru a 30A fuse, then thru a big relay switched my by ignition switch. The relay powers up fusebox B which all the accessories are tied into.
It was the 30A fuse that blew. The 3G is the only change I've made since adding the 2nd fan a month ago. It ran fine for a week in Moab with the 2nd fan. I never blew that fuse with the original alternator.
Is 30A not big enough for 2 fans, fuel injection, minimal lights, cb, etc. ? Have I just been underpowering all my electronics with the original alternator and that's why it never blew?
