Greetings, Can anybody help, I have Rita ign' 12v useing 2 6v mini coils in (series)?. I broke down a long time ago, Faulty front coil, I was lucky to have in my bag a 12v mini coil, Started well and got home ok, But slow running was changed i.e. faster. Spoke to the Rita man,told him I didn't like small coils, Had trouble years ago,He said use 12v double coil, "But it will not rev' past 5800" Thats OK I said. He sold me one and it's been on for some time,It always started better with 2 6v coils, (Why) ?. I know that putting 2 6v batteries in series gives you 12v but i can't work out how much power goes to each 6v coil ? and what happened when I used one 12v and one 6v to get home, Rita man said it did no damage. Am thinking of going back to 2 6v but I need to no why, Please keep it simple as my head hurts !! Cheers Bill.
