I need to know how to simulate a power draw in a circuit. Please let me explain.
I've installed a HID headlight on my motorcycle that had a stock H4 55/60 watt bulb OEM. The issue I'm having is that since the new HID setup is not powered off the stock 3 prong headlight plug, it appears that the canbus/main dme computer is sensing that there is a bulb out and is giving me a lamp fault on my display on the dash. The voltage running through the headlight bulb when engine is on and bulb is lit is 13.8 volts. As mentioned, the bulb is a 55w low and 60w high beam.
The way the new HID system is set up, it is powered from the battery so does not draw any appreciable current through the factory bulb plug, hence the computer thinking that a bulb is out and subsequent lamp fault. The OEM factory plug is still used in the system, but just as a switch to tell the igniter/ballast to turn on but does not power the bulb and the draw is obviously too low.
Perhaps I'm a ways off but I tried to use a 4 ohm 50W resistor inline on the ground wire at the stock headlight plug on the HID side to simulate a current draw. The exact resistance I came up with based on 13.8V and a 55w bulb was 3.46 ohms but I figured that 5 ohms might work assuming the computer won't produce a fault until a certain threshold, below the 47w/5ohm resistor value.
So, is it incorrect of me to wire the resistor inline on the ground wire? Am I completely off with how I want to trick the circuit?
thanks in advance
