Hi, Johan & all: I have looked for a 6-V jump start pack but found none. I jump started many 6-Volt cars with 12-Volt batteries back in the Midwest winter 50's when the 12-Volt battery Voltage was probably lower due to the cold weather. I have jump started mine with 12-Volts, but feel this could be damaging to the ignition and/or charging system. I also recall some cars like the big old straight-eight Packards had 8-Volt systems. The 6-Volt light bulbs usually were rated at 6-8 Volts and I imagine the few accessories on a C-300 would work just fine on 8 Volts. The radio and fuel gauge are questionable. Whether the generator and Voltage regulator could be set up to keep the battery charged is beyond my expertise or memory, but seems it could be done. I do keep a second full-charged 6-Volt battery in the trunk for emergencies. I'm sure you have seen all the electrical tips for our C-300's, but to review: Positive and negative cables size to be proper and connections corrosion free. Voltage regulator and/or trickle charger set to keep a full charge on the system. Perhaps a multi-viscosity oil for cold Swedish climate. I have found a Group 2 battery that has some extra power. It is a Workaholic (By Interstate Batteries) Group 2XHD, 600 CCA, 750 CA. You might be able to find something similar at a boat or recreational vehicle dealer. If I can keep some gasoline in the carbs, the car starts well. I have not yet solved the incredible disappearing gasoline problem, but a hot block tends to evaporate the fuel from the glass bowls and carb bowls and requires removal of the air cleaner and priming the carbs with gasoline to get a hot start after sitting a while.

No doubt why they changed to 12V for '56. In pictures of other club members C300's I can see some have 8V batteries. Anybody having good experience from these? I have been looking for a 6V Jump Starter to have in the car as a backup when going on trips but I can not find any other than 12 or 24V. Is there someone out there who knows where to find one for 6 volt? Thanks!
