M eletrical parts

[d. coleman]

does anyone have info or P/N for a resistor on ignition switch for generator? would Radio shack carrie this resistor? also cut-out relay at Napa? my jd dealer wants a fortune for "M" parts, would like to save some on small parts. thanks, d. coleman

d.coleman,
The part number is 1838155, and my notes say that M-Man measured a NOS one and it measured 3.1 ohms. Your generator has a maximum field current of 3 amps, so 6 volts x 3 amps indicates 18 watts are disapated if the field current is fed to ground. So, a resistor wattage rating of 20 or 25 watts would be adequate. You can try RS, but I have better luck at a local electronics supply place. It may not be real cheap, but should be less than 15 bucks.

You might be better off considering a new switch which would include the current control resistor (I assume replacement ones do, if they are designed to be used with a cutout).

Your local NAPA dealer should have a generic 6V cutout and will probably have 2 grades - the cheaper ones may not have a good lifetime.....

DC, As I recall Rat Shack has like 1 ohm 20 watt power resistors and you could wire 3 in series (if you cant get a 3 ohm). Tractor Supply or Rural King type farm stores usually carry those what I call "fake" cutout relays which are merely a diode and can work for Pos or Neg ground at 6 or 12 volts or go see Jim there at Agri Services up in new York where Rob referred you. Dont forget the switch needs a good to frame ground so it can connect the gennys Field direct to ground (high charge) or via the resistors to ground (low charge).

thanks, will be working on that area of the "M" today. d. coleman
