<VV> Charging disconnect wiring

With the internal regulator model, just put the switch in the ""field" 
lead. That is the lead that goes between one of the tandem blade 
terminals and the +12V bolt terminal. I would switch it on/off at idle. 
Run 16 ga wire, should handle the current fine. You might want to fuse 
or circuit breaker the hot lead for safety at 15 amps. Of course you can 
find a hot under the dash, switched with ignition is best, and just run 
one wire back.

Others can provide a wiring diagram.

I used the term "field" above, but it is actually goes to the internal 
regulator. It is not the wire that powers the dash light for a problem.
