Hi gents

I was replacing a radiator switch the other day and cleaning and lubricating pulleys in the engine as far I could see, and I noticed the alternator cable seemed really old, and I even looked under the boot and it seemed a bit dirty to me. I was thinking of replacing this cable and was wondering if it is the only one that is hooked up to the alternator. All I can see in the diagrams is this one cable that runs from the alternator to the starter, but wanted to know if there is another I didn’t see. Thanks
