I needed to replace the battery and I’d decided to ditch the regulator/ rectifier components, so this was a discrete piece of work. It involved deciding on the type of battery, mounting it and getting a replacement regulator/ rectifier. The alternator is similar to that used on BMW motorcycles of the era and is strong enough, so it didn’t need replacement or update. I decided to use a Lithium battery and I bought a new regulator to suit it (Lithium batteries have different needs to lead acid ones). Buying these was straightforward, but the installation work isn’t complete until the electrics are all fitted…
Here’s the battery, along with the footbrake master cylinder. You can see just how many leads had to be connected to the battery! The earth (-ve) terminal is on the right.
