Battery Cut Off Question

You cannot just "T" into the existing output wire from the alternator.

1. Make sure you located the output terminal from the alternator (it is a stud, the other two push on terminals are the field wires).

2. Disconnect the existing output wire and cover the end so it cannot short out. Some heat shrink tubing and electrical tape should do the trick - just remove and reattach to return car to stock later on.

Side note: The output wire from the alternator on a stock wiring harness is connected to the battery, but it takes a long route to get there, including two trips through the bulkhead connector, a trip through the ammeter etc. Not sure how you have rewired your car when you relocated the battery, so use common sense!

3. Make a new wire to go from the output stud on the alternator to the battery in the trunk. I would use 8ga wire and think about a section of 10ga fusible link at the alternator end - should be able to get a fusible link from the help section of the local auto parts.

Another Note: When you make the alternator connect directly to the battery like this, the factory ammeter will no long read correctly. That's OK, they are a terrible way of telling the state of your charging system anyway!

Hope that helps!
