Cat D5g xl keyed power issue

[squeak24]

I have a cat d5g xl dozer (serial # 00d5gpfdh00620). I have power at the key switch and at the fuse panel for the key, when the key is turned on to power up, I loose power at the key and at the fuse panel. I can take a jumper from the battery to the the fuse panel to the wire that goes to the key switch, and everything works fine. I am somehow loosing power going to the fuse panel. Does anybody have a wiring diagram or can tell me where power comes from to power the fuse panel. Im sure its just a connector somewhere that might be corroded. Thanks.

Nige, It was the connector under the steps on the left side. There was a broken pin on the connector, thanks for the help.
