[QUOTE]Originally posted by Tom Renzo: [QB] Just because an ALT is 130A Does not mean it will put out anywhere near that. Normally it will never reach half it's output at best. We use the stock wiring in most cases with absolutely no issues whatsoever. Remember the alt only supplies the current your car requires and normally the battery recovers rather quickly after the initial start. In order for the alt to put out 100% charge rate it has to spin at Max RPM Normally 16,000 RPM and have a very heavy load. Adding a heavy feed wire is always good but most people go overboard on it. A Number 8 or 6 AWG is fine for just about any car on the road today. And as far as grounding the case of the alt is your ground on the system. And always use a fuse breaker or link if you install a new feed wire.(we normally dont do this because it is not necessary in most cases). Normally a protector somewhere around 100A max is what we use. having to big a protector can cause more troubles. If you have the alt i am thinking about it has 2 heavy feed wires on a heavy plug. If you parallel them they are plenty big enough for your instillation. The fire hazard on those old non lug alternators were the plug arrangement not the wiring. [/QB][/QUOTE]
