Hi,
I'm about to wire in a Powerdynamo on my ETZ250. Two questions:
Is it worth wiring a large diode in series to prevent accidental mis-wiring of + and - of the battery in future? Ie something to idiot-proof replacing the battery in a few years or tinkering with the electrics and accidentally short something? Is one diode enough or something more somewhere to protect the delicate circuitry?
Secondly, what's the estimated life of the Powerdynamo - are there any spares (of the Powerdynamo bits) worth carrying if touring or is that not necessary?
Thanks
