Hi Waldo,

Thanks for all of your responses on my post "Alternator Wiring Schematics." I am currently getting all of the wiring together and almost to point of installing the alternator.

I have an additional problem I was hoping you might be able to help me with. What is the main battery source to cab? In other words, which wire powers the cab?

I can get power to cab, but I'm not sure it's the right wire because the power is constant top the cab even when the key is out of the ignition! What regulates power to cab so I don't run my battery out when the truck is off? Or, is there always power to cab in these older trucks?

Any help would be appreciated!
