    At least 10 gauge, maybe even 8 if you have a lot of stuff running through it.

  3. If using a generator, an ammeter is the correct choice for monitoring charging system operation and a #10 wire will be adequate. If you're using an alternator, it may not give you a true picture and the wire needs to be sized to the maximum possible continuous load when driving. A voltmeter will be a far better choice. This is because generators and alternators don't produce their power outputs in the same way even though they operate on the same basic principle.
