anyway, when the next alternator goes in and doesn't make a difference i'm going to do what bmg suggested - disconnect the battery-starter-altB+ cable and run a new one externally. my christmas present to me... battery cable....
i could go on and on about this...
tiger is right - KISS ... well ... battery cable... simple... stupid...
i bet a lot of people have this problem and don't even notice... i'm sure the voltage drop is happening there... it's the only thing anywhere near anything that gets warm and the voltage drop happens when the engine gets warm... you can (well... i can...) see the starter cable is corroded as nuts.
here is the diagram again
connector X964 is buried here
i'm going shopping soon... i have to make some kind of terminal in the area marked by the yellow... errr.... rectangle kind of thing i 'drew'. then i will send a battery cable each to the battery and starter and some kind of suitable cable to the alternator.
i am loosely following shogun's thread and praying i can get through winter with this. tips appreciated...
