You beat me to it L.S. I saw your point about using too large a battery if infrequent short journeys are common, Lead acid battery life and efficiency are optimum when kept fully charged. The physical restrictions in the engine bay will probably limit choice anyway though.

There are pros and cons to that idea, does your C-Tek charger have desulphation circuitry built in?

All up and running.Now what is the position re' fuses ? Currently horn, heater and wipers 25.amp. 8.amp the rest. BTW still have 6volt horn running on 12V, have a 12V will possibly change later

Ron, re' fuel gauge.I tried it with resister but probably didn't get it right. No fuel gauge or oil / charge lights. Removed resister and every thing works fine, even fuel gauge seems to be no problem.Can't guarantee it's veracity at this moment but never really could.

Any idea what current it pulls at 6V and full speed?
