thank u i have bought 4 new batteries and goin to try to get her goin this weekend should the batteries be hot on negative side?

i have bought a 1968 r model ex concrete truck i cant get it runnin yet but somebody told me this truck could be positive ground i have worked around equipment all my life never saw positive grounding unless maybe 24 volt? does any 1 have any things to look for before i burn something up? could this truck have positive ground??

DO you have the model & vin number? I can see what pops up in the MackNet! Or you can call The Mack Museum for tons of info. The number is in our featured links section...

yes i will get it and put it on here this eve
