I brought this charger off ebay ages ago.
When I plugged it into my bike, it showed an error. After some research on here I found out that having autocom wired to the back of the acessory socket can throw up a fault, however, I then sold it onto a tosser and he had the same fault without an autocom. So this is a boxed optimate with instructions but it has a fault, so if anyone fancies having a go at fixing it they are welcome to collect it from Woodley (near Reading Berks).
One condition - if it works for you without any fixing then I would appreciate a charitable donation to the Calum's Road trip.
Cheers
