Speedo light and ammeter



As usual, click any image to zoom in.



We bought Mark a new ammeter for Christmas.
As it happens, guys 'n' gals, how's about that then, he didn't seem too enthused so we also had to get him a new kickstart rubber, a t-shirt, a mug, and a BSA star. Kids today, eh?
Anyway, after us putting him through school, A-Levels, and a Masters degree in Microelectronic Systems Engineering he came up with this little beauty. Education is a wonderful thing, n'est-ce pas?

"Apparently", he was stopped the other night and asked how fast his speedo told him he was going. He replied, "Are you MAD, officer? At that speed I was keeping my eyes on the ROAD!"

Truth is there was no light in the speedo so he ordered five 12v LEDS (with the obligatory 470Ω resistors) which is what you can see here as a PIERCING LIGHT.


Mark has spent the morning wrestling with the joys of putting big butch manly fists (inherited from his dear mother, mange tout) inside the headlight of a BSA C15 and now has nocturnal illumination aplenty.
New Earth (orange cable) run from ignition coil mount to the headlight – visible just to left/below centre in the shot on the right with the red/blue connector.
