Overdrive R-9 from 6V to 12V

Posted by Jan Alvemark On 2014/8/28 13:13:26

Hi you big resource of knowledge. I'm going to convert my 1949 Packard to 12V and the only problem I can see is the solenoid for the overdrive (B/W R-9). I've been reading that the solenoid has to be changed to a 12V solenoid because it's not possible to put a voltage reducer on it. This is as far as I can understand because it's two coils inside it. My question is: Why can't I put one reducer on each coil? The relay is supposed to be OK with 12V...
