Are the two battery connected in series for 24 Volt or in parrallel for 12 Volt on the Case 850D loader
Apparently The 850D can be either 24 or 12 volts. You will need to determine the alternator and / or starter voltage on you particular machine. Here is a link to the online parts book for an 850D. http://partstore.casece.com/us/parts-search.html#epc::mr49481ar959172
Seems to me to be a misprint, the starter and all the lights are listed as 24 volt only.
