I've trouble shooted a fair number or starting problems in my days, but haven't run into an in-line fuse to a starter yet. I've tested for juice at the starter terminal before with an indication that it wasn't hot when in fact the ground was so bad that the test light wouldn't light up. A more common problems with starters is the solenoid contacts getting so burned that it won't pass the juice to the starter motor. That's usually indicated by a loud click when you press the button with nothing else happening.
I've been having a few starter problems myself on our July trip to Desolation Sound. Thank goodness for the compression release or I wouldn't have got her started at the fuel dock after a long day of motoring. Checked for voltage drop to the starter, haven't checked the grounds yet, but leaning towards jerking the starter to see how the brushes are doing as there are 2000 hrs on the XP-25
