RE HEADLAMP WIRING. ------------------- Referring to PN{Mr Northey}1/PH.10.2.31. we do not agree that there is any measurable loss of voltage due to the sectional area of the wiring used for the lamps. We have tried this out on a chassis by taking voltages with lamps on, directly at the battery terminals and then at the head-lamp terminals, and find that the drop on voltage is :- Battery Voltage 13.2 Headlamp " 13.0 a drop which you will agree is quite negligible.
