Hi,
I've noticed something odd with my C5: I'll be going along with light motor load - inside the green section, going on the flat. Motor presumably running nice and cool. Then when I go over even the smallest bump in the road, the motor will cut out without without warning - my motor load indicator flashes but the battery indicator doesn't. If i switch off the ignition then switch it back on again, it will carry on going quite happily until the next bump. I try to avoid potholes and the like, but this happens even on small bumps eg where they've dug a trench through the road and filled it in. Sometimes even it's just barely visible dips in the road surface which I only notice as a slight shaking of the chassis when I go over them.
Anyone know what's up here? Could it be some sort of contact intermittency triggered by the shaking?
Thanks
Alec
Hi do you have the original key switch if so the problem is there they have allways been a problem.

Chas, I do indeed. Is this a known bug with it? As I mentioned in another thread, I'm looking to replace the batteries and may do away with the original battery top and keyswitch. That won't be 'till the new year though.
Yes it is ....Chas

I see. Is it just the vibration breaking the contact in the keyswitch mechanism? I wonder if spraying a bit of contact cleaner in it and on the battery contacts will help?
You could try it and see ....
I had this issue once when using a different battery top to usual. I bent the contacts on the battery top back, towards the back of the C5, a tad and I haven't had an issue since.
Chas, kamilb1998: I tried both of these things (contact cleaner and bending the contacts) and the combination of the two seems to have worked. I drove it all the way from the engineering dept back to my house (about 4km) without a single cutout. Horray! Thanks for the suggestions.
You could try one of Chas's wiring kits, I wouldn't trust the old key switch assembly :P
People do criticise the original key switch but I think its perfectly adequate if maintained well. I use my C5 daily and have done a good few thousand miles with the key switch and I can't remember the last time it gave me any issues.
