Hi peoples
I am putting a ea81 motor in my BAJA and would like to find out where the wires from the alternator go in the beetle wiring?

I know that the screw type fitting goes to the battery.
there is also two push on fittings and on the label it marks these plugs as "W " and " S " now one of these must be for the charge light but which one and where does the other one go to.

Thanks for any help

Marc

Internally regulated?
Is there only S and W? Both the same size?

I'm assuming you have a B+ terminal (Direct to battery if internally regulated) The W is most likely the tachometer signal wire and the S from memory is a battery voltage sensing wire... I might be wrong with the S though.
Is there also a D+ terminal (To go from your ignition switch, through a suitable bulb/resistor then into your field windings)?

mine has a thick white wire (this goes to battery +ve), white/red wire, this goes to light (idiot/charge light).

there is one more wire, looks white to me (same size as the white/red one) which doesn't appear on the electrical diagram I have. The diagram indicates a B/W (i assumed this was black/white) that goes to Battery +ve.

Maybe you can post here (or in the EA81 wiring info http://forums.aussieveedubbers.com/viewtopic.php?tid=57308 thread) what you found to work.

Just as long as you know it needs a decent resistance i the charge light circuit, if you connect it straight to 12v + terminal your alternator will not charge.
The system/circuit needs the load which is applied by the bulb (Which also may need a resistor installed too depending on the wattage of the bulb)
Remember Ohm's law don't you?
