| | | | Joined: Feb 2008 Posts: 21 Apprentice | | Apprentice Joined: Feb 2008 Posts: 21 | Does anyone know where I can get a wiring schematic for a 39 Chevy truck 1/2 ton? I have converted many things to 12v (battery, coil, light switch, lights, heater switch, ignition switch) The only things that are 6v are the gauges which i believe I can run reducers to and the distributor.
Here are my questions...
Does the ammeter need a reducer? (I was told no)
My 12v light switch has terminlas (battery, lights, taillights, parking lights) all the directions I have are for the a 38 12v harness which i was told is the same and those directions refer to connecting to term H, term S, term R...can anyone convert that?
I have an alternator (Chevy) has 2 terminals in back and a 2 wire snap in connector, can anyone tell me what goes where there?
Does someone have a 6v to 12v conversion diagram
I think if I had a schematic, it would be easier,
Help

Your ammeter needs no reducer. Does your alternator have its plug on the actual 'back' of the case? Are the terminals marked R and F in little raised letters on the case?
This plug is referred to as the DA plug and it's how your alternator is powered and how it keeps tabs on the state of charge of your system. If your alternator actually has its DA plug located on the back of the case, as opposed to the circumference of the case, it's an old style that uses an external regulator, which is what you probably do not want.
Take a look and let us know which style you have.

If the DA plug is on the periphery of the case, then yes, it's internally regulated. The tabs will look like this --, and should be marked 1 & 2. Wire #1 will go to a switched (key) source of power and wire #2 will tie into the system to monitor voltage...this is easily accomplished by wrapping it around to the large BATT lug.
