mo.blaze - power resistors
If a control unit (ECU) controls the original turn signals and the accessory turn signals do not flash at the correct flashing frequency, power resistors must be installed.
This works, only if the original turn signals have more power consumption (Watt) than the new LED turn signals! Motorcycles that already have LED turn signals installed from the factory may have less wattage than the mo.blaze products. This should be checked before purchasing!
CAUTION! The power resistors can get very hot during operation. Therefore, do not install them near the fuel line, tank, or other heat sensitive parts such as the fairing.
mo.blaze power consumption:
mo.blaze pin approx. 3 Watt
mo.blaze disc approx. 7 Watt
mo.blaze cone approx. 3 Watt
mo.blaze ice approx. 3 Watt
mo.blaze tens 1 approx. 1 Watt
mo.blaze tens 2 approx. 2 Watt
mo.blaze tens 4 approx. 4 Watt
Here, an example is used to calculate the power resistances.
Details:
- on-board voltage 12V
- Power consumption of the original turn signals 21W each
- Power consumption of the new turn signals mo.blaze pin 3 Watt each
1. Calculate how much power the flasher relay needs to work properly.
- Usually the power consumption in Watt is written on the metal body of the bulbs or on the lens/glass body of the flasher.
In the example, we assume 21 Watt per flasher.
2. Determine the power of the new turn signals.
In this case, this is the 3 power consumption (Watt) of power used by the mo.blaze pin.
3. Old consumption minus new consumption gives the required difference in power consumption (Watt) 21 Watt – 3 Watt = 18 Watt.
4. Calculate resistance value using the following formula. R = U×U / P
U is the on-board voltage of 12V and for P the calculated difference of 18 Watt.
This results in a resistance value of 8 Ohm and a heat output of at least 25 Watt. Such resistors can be found in electrical stores or on the Internet. Often no exact value can be found, in this case the next larger resistor should be used. In the example, it would be an 8.2 Ohm resistance.
The resistors must be connected in parallel to each mo.blaze pin. The following picture shows a simplified example.
