Cat 303.5 blowing fuse on startup

[GH75]

I own a 2000 Cat 303.5. S/N afwoo288 and am wondering if anyone has fuse box diagram that they’d be willing to send me. My machine keeps blowing a 10amp fuse when attempting to start and I’d like to be able to attempt to retrace the possible wiring short but have no idea what direction I’m going in. Thanks

When you say attempting to start, do you mean when you engage the starter? Does the fuse blow when you turn on the ignition from the key switch before you go to the start position?

It blows the fuse when the key is turned and the starter is engaged.

Ok on further inspection my initial response was incorrect. The fuse blows when the key turns from the off position to the first engagement point. Not when turned completely to engage the starter.
