12V-6V Resistor Heat

Bud W · Jul 9, 2010

I noticed that the 12 volt to 6 volt resistor on one of my tractors gets too hot to handle within a minute or so of turning the switch on. I checked the voltage and with 12 volts in I seem to have about 4.5 volts out. Looking at the resistor it appears to be in good condition ( no corrosion ). Is this normal. Its hot enough that you cannot hold it in your hand. Thanks

they do get hot, especially if the points are closed with the ignition switch on, engine off.

Yep they do in fact get good and hot that is why most are made of a ceramic type stuff so as to take the heat.

When it runs the points are closed less than 50% of the time, plus there is usually air movement. They do get hot. Jim
