On another manual it says it should be positive, what should it be, anyone any definite answers. :? Quote Link to comment Share on other sites More sharing options...
0 Degsy Posted February 7, 2007 Share Posted February 7, 2007 I can't say for certain about your Morris but I think British vehicles were pos earth until some time in the sixties. Quote Link to comment Share on other sites More sharing options...
0 john wheatley (R.I.P.) Posted February 7, 2007 Share Posted February 7, 2007 According to my book of words the Morris 15 cwt. is negative earth, quote "The negative terminal is earthed via the starter motor to the offside chassis frame side member" Any help to you? :rtfm: John.

0 Richard Farrant Posted February 7, 2007 Share Posted February 7, 2007 I can't say for certain about your Morris but I think British vehicles were pos earth until some time in the sixties. A lot of British military vehicles during WW2 / Forties, were negative earth, but there were some oddities, for instance, the Austin lorries supplied for civilian transport, National Fire Service, etc., were positive earth, where as those supplied to the War Department were negative earth. Difference being the dynamo and regulator types. Quote Link to comment Share on other sites More sharing options...
