To Those Who Dabble In The Dark Arts Of Auto Electric (Alternator Problems?)

Run the gauge as directly to the battery as possible rather than through wiring harness, use a fused or fuse link wire and ground as close to it as well.
To many feet of wire and too many connections will cause issues.
Another issue is to many companies only do machine crimps, I have worked on many of the newer systems and had to go through and solder the crimps to fix minor electrical gremlins.
I watched one company that used to tin and solder connections and and heat them as they crimped the terminal, this made a very good connection and as long as properly supported and done it makes better connections.
I read that some of the people at Painless people dont believe in soldering crimped connections but I have found I have better luck doing it.
I have several customers who I wired race cars and if I crimped them only I always had to go back and fix issues. So now I crimp and sold the connections, I put a tool kit in the cars right next to the driver, they get all the parts they need to do quick fixes at the line then I resolder them later on.
