I am in the process of converting my truck to 12 volt, in fact i am completely done with it EXCEPT, i tested my ballast resistor before i tried to start it. My battery was at 14 volts and after the resistor it read 11 volts. i am using a resistor that i have seen on many applications very similar to this, will i be ok? Also this is the resistor
