Had not ridden my Tenere for a few weeks and no surprise, the battery was flat.

It bump started ok and I set off from SE London towards Oxford.

I had not noticed the headlamp was not working until it started to get dark and I pulled into a backstreet bike shop in Oxford.

The 20A fuse had blown, put in the spare, it blew. Put in a 30A fuse and the low beam bulb exploded. Swapped the bulb, works fine, so I rode home.

So, question.... Would bump starting the bike cause a surge that somehow damaged (shorted) the bulb then blow a fuse? or is there likely to be another fault somewhere waiting to err it's ugly head?

Or it could just be coincidence!

That is what I think.

I bump started my a few times without problem. Look at all the connections and broken wires (especially under the tank)

I have never believed in coincidences..........

I can't see how bump starting a big single would cause a surge in anything except your perspiration rate.

My guess would be a dead short in the headlight bulb, which you have now cured with a new one.

hi, I believe it's merely a coincidence, the H7 bulbs are fickle and fragile. I have seen plenty having an internal short blowing the fuse, happened once on the ten on a backroad in wales, of course at night!

as for the flat battery do you have accessory's such as an alarm? was the battery completely flat?. more of a concern if it continues
