Who do you know that has a"good idea"????
Not up to date on the 800m, but would suggest this as 2 cents worth.
First: I am not sure of what he means by "the splitter between batteries blowing fuses"
sounds as if there is a large main fuse in there, so if it is failing, better check ALL connections,
cables are good, starter for operation[ bushings/brushes/dirt] the series/parallel switch may be
failing/welded contacts, batteries not fully charged[charge voltage down= amps up], and
include the ground switch connection also.
If it the small control fuse of the series/parallel switch, check ground and condition of the switch
circuit, connections at the fuse?, not sure if same fuse runs switch and solenoid on starter? to be checked?
your Ivan and its cousins have 12 volt starters on them, and us 24 volt for starting them and 12 volt run, so assuming
that the 800 is similar, hook the batteries in parallel for 12 volts, small change in control wiring maybe.
and eliminate the series/parallel switch altogether.
Tractor will roll and start but he has to keep the batteries up and checked a bit more often for charge condition,
at times one will fail and not charge as it is running, and depending on where he taps off the 12volt control, it might
not operate the starter solenoid[ just clicks] because it has not been getting its share of output from the alternator.
works for me on my Russian princess, think we could mate our two 400's and get a 800 ?
hope it helps him
take care ok
