Hero Honda CBZ 160 Illumination Problems, I need help with this problem and how I correct it.
10.84 volts barely arrive to the front lampping connector, the bulb is 12V/35W which barely illuminates its intensity is not like that of other motorcycles, they told me that it was the regulator and changed it but I do not improve at all, continue with the same voltage and intensity, since I am eighteen that this type of motorcycle takes the voltage of the coils and not directly from the bacteria Or as I do to know if the coils generate enough amperage for the loading of this bulb, which I must do to be able to solve this problem, I hope your comments
thank you
