I have been riding everyday to work at 03.30a.m. except the 25/26 Dec, and the difference on the road is superb.
Cheers bud, Chris.
measure the voltage on the standard wiring loom with the H4 connector for the headlight, between the dip beam pin and the earth pin [with the engine running], and compare to the voltage across the battery terminals.
Voltage drop is the difference between the 2 readings, and represents the effect of thin wiring & switch gear resistance.
There should be no need to have the connector plugged into the headlight as resistance is the same even with no current flowing.
No probs about the bulb, you needed a fast solution if you are out riding in this..............any one else want to buy my other 80/100w bulb.
