Anyone have a simple wiring diagram for converting a B/C 6 volt wiring system to a voltage regulator instead of the cutout relay? Thanks, Mike. ------------- 39B 42B 48C SFW 52Cub Cub Cadet 70 S14 Speedex M14 Speedex S18 Speedex |

 The cut out system has the field from the generator going to a resistor on the original light switch. Low charge is through the resistor, and the resistor is bypassed straight to ground when the switch is pulled out for lights or for full charge.  The regulator system has the field going to the regulator, eliminating the need for the 3 position switch. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |
