2014 John deere WAM electrical troubleshooting

[Green35]

We have a 2014 WAM that blew the 15 amp main electrical fuse replaced it and ran for 2 to 3 more hours.We tried to crank it up the next day and nothing fuse is good battery was old and worn out so we switched with our other batwing still nothing.So then put cables on it sounds like its charging up "beeping gets louder the longer you wait to crank it". Battery is good ignition switch is good jumped out a diode and we get the fuel pump to come on but don't know where to go from there any help would be appreciated.

There are two diodes on your machine from what I see on the Deere web site.
Knowing what they are for, I don't understand your comment of "jumped out a diode.|"
Do you have or can you buy a cheap multi meter.
Once you have that I suggest you do the voltage drop tests outlined starting at page 8 of the DENSO starting trouble shooting guide.
