Well , my 48 cub is done , except for one thing .On a different thread I had started I said I burned my resistor coil , I now have 2 new ones and I'm ready to put one on .
Before I do tho , I want to make sure it's wired right . So, as you would look at the back of a 4 position switch I have the F wire hooked to the F resistor band at the bottom right , the A wire hooked to the right side of the amp gauge , and the other side of the amp gauge is wired to the starter .I have the lights wired right I know. Is this right ? I bought 2 new resistors because I figured I'd smoke one of them . I know this should be simple but in my case it may as well be algebra 4 . One other thing , when I burned the last resistor I didn't have the wire from the amp gauge to starter connected . Could that have caused it to melt?

Re: Low resistor coil
You also need a wire from the right side of Ammeter to BAT connection on the Cutout. Below diagram should help. This diagram applies to a cub w/ magneto and cutout.

Re: Low resistor coil
That's the one I'm calling the A wire and its wired to the right side of the amp gauge, so I guess I'm good . But could not having the wire from the amp gauge to starter be the reason thelast one melted ? Thanks Bill

Re: Low resistor coil
I went ahead and put the resistor on ------ no smoke but, it's not showing a charge either. In fact maybe a -1 amp, is that normal ?

Re: Low resistor coil
No not normal, unless you have the lights on. If wired correctly and the generator and cutout (or voltage regulator) are operating correctly, it should eventually show a charge, especially at higher rpms. Also, if you disconnected the generator, you need to polarize it to match the battery polarity.

Re: Low resistor coil
At one time it was off the tractor, how do you polarize it ?

Using a short length of jumper wire you simply make a momentary connection between the Batt and Gen terminals on the cutout (or voltage regulator). You should get a little spark. Do this with the tractor not running.
