Resistance in D Switch

[Joel Sanderson]

My D is 12 volt, and I made the mistake of putting in a 6 volt switch. Oops. The resistor in it doesn't have enough resistance to affect the field, so it puts out 17+ volts, and my batteries overcharge and die an early death. (They also undercharge at idle.) I haven't been able to find the correct 12-volt switch (AF688R) anywhere--only 6 volt ones. Does anyone know where to get one for 12 volts? OR, could someone tell me how much resistance, in OHMS, the 12 volt switch has, so that I can add a resistor to the line to make this one work?

Thanks

Unless someone can come up with a value for you, measure the resistance of the present resistor and add one of similar value to the F lead and see what happens.

I dont have the correct ohms value some Ive seen best I recall (no warrantly long time ago lol) are in the 2 to 3+ ohms range plus or minus.. HIGH charge or when lights are on gives the field a dead ground. In the high charge Id expect a good working system at fast RPM to charge the battery at 13 to 14 volts, at low maybe 12.8 to 13 ??? ONLY A GUESS........... If a lot over 14+ for extended time it may over charge.

Sorry no more help
