[QUOTE="Mystic Knight, post: 3145771, member: 574367"] Ya it looks cool but I'm having some charging problems right now that are driving me crazy. The battery didn't seem to want to hold a charge. I took my Red Top to get it tested and they said it's good. For some reason it'd be drained by the time I drove somewhere and it sat for the day (car shows, etc). I threw my Red Top from my other truck in and it had the same problem but took longer to be an issue. At the last show it wouldn't even turn over. We got into it right there at the show and realized there was a big bundle of wires to the starter that had melted from the heat from the headers. I got it home and rewired the entire starter away from the headers then wrapped the wire in heat wrap. I also double checked all the grounds at the frame, engine, and body. Now it starts whenever there's a charge but the battery still seemed to drain. I started thinking about it and thought "Hm, I haven't even thought about the alt". So I pulled it and had it tested. DOA. I also found out the POS alternator was only a 65 amp. After making the guy at the auto store pull a few different alternators I found a 124 amp alternator for a 2000 full size Chevy that works and bolts right up. I started a trickle charge on the battery last night. Tonight I'm going to wire up the voltage meter for the truck so I can see what it's at after the charge, after it's run a while, and after it's sat for 24 hours. That should give me a better idea whether it's a bad battery or something inside the truck draining it. Ah the joys of a fully custom truck... [/QUOTE]
