serf2 Posted November 19, 2011 Share Posted November 19, 2011 Does a 1952 A-30 have a 6 volt system or 12 volt and is it positive or negative ground. Thanks in advanced Quote Link to comment https://www.bigmacktrucks.com/topic/21693-1952-a-30-batteries/ Share on other sites More sharing options...
yarnall Posted November 19, 2011 Share Posted November 19, 2011 Mark,My bet is 6 volt with positve ground. That is what the 405 A that I got from you is. If you got the info from the mack museum on the truck it should tell you what the batteries were, but probably not the positive ground part.Michael Quote Link to comment https://www.bigmacktrucks.com/topic/21693-1952-a-30-batteries/#findComment-91314 Share on other sites More sharing options...
serf2 Posted November 19, 2011 Author Share Posted November 19, 2011 Hi Mike This is the truck we worked on at school for that company in Downingtown. I'll email you a picture.
