They have a half dozen or so relays that are rated to 30-40 amps. AND, they use the same wiring numbers as our cars. Also, I was just looking through some of my old notes from VW electrical school, and found the complete specs on 6V and 12V generators. A 12V generator has a cut in speed of 2200-2300 rpm. That is shaft speed of the generator. And I think, Jim can correct me if I am wrong, we have about a 2.3:1 ratio with the crankshaft. That means our generators start charging at about 1000rpm crank speed. If you head lights dim at a stop light, turn you idle up a little. And if you want more staying power, parallel a second battery under the other side of the rear seat. Someplace I have the schematics to do this and wire it so when the engine is off, you pull from the aux battery, and when the engine starts, it automatically starts recharging off the system. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) '05 KIA Sorento SUV russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
