Being new to Riley One Point Fives, are they all positive eart or did it change to negative earth with the later models. If so when did the change occur?

Hi, I believe they should all be positive earth - unless anyone can prove otherwise.
Doesn't really matter - unless you are using modern radios or electrical equipment. If you do want to change from positive to negative - it is a very straightforward operation that should take more than a few minutes!

Hi Roger, thank you. Reason for asking is I have Radiomobile radio from mid sixties that has been converted to FM but is negative earth. When I find a Riley to buy I want to fit it, so will need to convert to negative earth.
Where can I find out how to do this
Thanks again
Mike

When I find a Riley to buy I want to fit it, so will need to convert to negative earth. Hello Mike, Roger nailed it, all of our little rockets are positive earth from factory. You will not be obliged change polarity if you do not wish to. I wrote an article in the Riley record a few years ago about my solution to this polarity issue. FWIW I like to keep the one-point-five 'pure' so I like dynamos, external voltage regulators that sort of thing. One can buy a magical device, a power inverter .  This device is small, looks period correct under bonnet, and will accommodate low draw items, eg: radios, 12v plug for GPS, phone charger that sort of thing. I installed a cassette deck AM/FM radio and a plug under the knee rail adjacent to the steering column. Dead easy to install and is fused,   Works great for me an option you may consider. Best of luck in your search for a one-point-five salut Bruce. |

Bruce, thank you for this. Interesting! I was thinking of converting a Riley I find to negative earth so I could fit an alternator and my radio, 12 v socket for sat nav but you pose an alternative to think about.
IF i do decide to do it "your way" where can I obtain an inverter and instructions for fitting etc and exactly what is it called?
All I have to do now is find a One-Point-Five, so if you know of one.......
Many thanks,
Mike
