Push the brushes down versus their springs, and insert your "stick" in the holes in the comb holder to help keep them down inside the brush holder.

Using an ohmmeter, check the diodes, both equally regulator diodes (triode in Delcotron) and rectifier diodes. A diode is actually a "A method valve" for electrical energy, so Each and every diode really should clearly show some resistance looking through to the meter A method, and no reading, or infinite resistance the other way. A bad diode will possibly have infinite resistance both means, or will perform some present (demonstrate a examining about the meter) both equally means.
