On the cranking issue:

-make sure battery cables are heavy, 6 volt cables. Skinny 12 volt cables won't carry the amps required at starter

-assure all cable connections are clean and corrosion free

-run the ground cable directly to bolt holding starter motor, making sure of metal to metal contact

-have starter rebuilt if needed

Six volt cars start fine if connections are good with correct cables.

Oh, and really nice car you have there!

Thanks for that info David. I'll take a look. Someone mentioned an 8 volt battery that would be suitable and increase the cranking amps. I never heard of that.

8 volt batteries were common at one time but these days I've only seen them at battery rebuilders. If you used one, you'd need to adjust the regulator to have it charge enough for the battery. Most 6 volt systems I've seen seem to cut out around 7.5 volts or there about.

Best just do what Trimacar suggests.

BTW, nice car!
