MG MG Y Type - Battery History Question



Greetings to all.

Out of my ignorance, my interest, and due to a question asked me, could someone give me a quick history of MG T-series 6-volt(if ever) and conversion to 12-volt system?

Thanks for the schooling,

Jerry

Hi Jerry

The Y only ever carried a 12 volt battery so most wont be able to help you here. Not sure where you#d get the best answer but maybe someone here can help!

Not sure what info you are after as I thought most British cars were all 12 volts going way back, but we have an un-restored 1925 Willys Knight that we have had since 1986, converted to 12 volts several years ago.

Wiring, being designed for 6 volts, is more than adequate for 12 volt. You'd have to rewire with heavier gauge if you went the other way, not that you'd want to.

Things like light bulbs need to be replaced, and possibly the starter motor, although the WK is quite happy starting on 12 volts. A friend with an Essex went the same route and had to wire in some resistance in the starter circuit otherwise the starter cut in very violently.

The only other problem encountered was the klaxon, which nearly took off into orbit until I got hold of a ceramic resistor and tucked it up under the cowl to cut back the power getting to it.

None of the T-Series MG's were 6 volt - they all ran 12 volt systems, however the TA did have two 6 volt batteries to get to the 12 volts.

Some earlier models of MG than the T- Series had 6V systems, but I would have to do further book reading to say which ones. Certainly the M-Type has a 6V system.

As far as I'm aware all the post-1936 Nuffield cars (Morris/MG/Wolseley and Riley)ran 12V electrics, and the main components are widely shared, so parts are easily available, if that's your concern, Jerry. Dynamos, starters and control boxes are all standard Lucas parts shared by many cars of the same period.

Many thanks to my "Y-Type Brothers" for your responses.

A good buddy of mine in the states, going back to our army kinship, had said he thought T-Series cars went through a conversion from 6 to 12 in their evolution. Thanks for proving my sanity in saying he was mistaken - he's a "gear-head" for mostly U S muscle cars, anyway!

Many Thanks,

Jerry

G'day Jerry,
Maybe your mate was thinking about the Morris 8 Series E and Series M Morris 10 upon which the Y was based, with quite a few parts in common. Both of these models run 6 volt systems.

N. Wakeman,

Thank you for your comments and explanation for the 6-volter! I hope to re-visit your wonderful country/continent again someday. I spent almost a week in Sydney while on R & R from Viet Nam in 1968! I have never been treated as well anywhere else in the world! Pass that message around to all your mates!

Regards,

Jerry
