I have a long range tank on my s1 and have mounted my battery in space between rear mudguard and frame and my series 2 it's inside toolbox. I have always used a battery it only needs to be 4ah

Cheers
You don't need the big fat cap, you can use these although a small battery would be better.

If space is an issue you could always use 2 or more very small batteries wired in parallel, ealry MGB's used to have 2 6 volt batteries wired in the same fashion.

I've just had a look on my S3 and the space is really tight around the mudguard and frame area. The battery would have to be very small, a burglar alarm battery might do the trick but even that might be too big. I'd also have to make up a mounting bracket. It looks possible but tricky. I'd have to relocate the all of the other electrical bibs and bobs to make room.

For the sake of simplicity I might stick to the capacitor option. The lights won't work without the engine running but that hasn't been a major issue for the last 30 years! At least I'll be able to charge a phone or run a sat nav.

From a brief bit of research, the bigger the capacitor the better. Ebay has a few listed at 15000 microfarads for just a couple of quid

LOL! You're right Mark, but I was trying to do three things at once and I forgot that when the air goes below a certain temperature my brain starts to shut down. :biggrin:


Anyway, Got it sorted.

So there it is. If I can do a DC conversion absolutely anyone can. :oops: :D
