Hello All, afraid I’m chasing for more help on the 1929/30 Excelsior electrics and in particular the wiring for the Miller headlamp (unfortunately the original wiring had gone by the time I got to work on the restoration so I have little to go on). To recap, the machine has a BTH mag/dyno feeding into a cutout coil. Standard 6v -ve earth; tail light, hooter, ammeter, headlight with 2 filament main beam and pilot light.
The accompanying photos show the headlight terminals numbered 1-8 (anticlockwise from the driver’s view). Numbers 2, 6 & 7 are wired terminals. The rotor has 4 positions (again, anticlockwise from drivers view) Off, C(harge), L(ow), H(igh).
I have worked out the bridging of the contacts as follows for each of these positions (the first column relates to the first bridging contact going anticlockwise from the control lever, the second to the second bridging contact)
Off 4+5 1
C 5+6 1+2
L 5+6+7 1+2+3
H 6+7 2+3+4
Any thoughts/ideas greatly appreciated!
Paul.
