finally got the 301 fixed. special thanks to 8850 dave for his help and the use of his manuals!! also to bob for steering me in the right direction. tractor would not charge and the battery and oil pressure lights would stay lit even with the ignition off. wiring was a rats nest. tractor uses a prestolite charging system, similiar to chrysler or amc. at some point in the past a jd reman alternator was put on. i got a new v-reg from deere, old one was burned. also a new reman alternator. the alt came in yesterday but had an external regulator mounted to it, along with a bracket that held two diodes, which the orig alt did not have. mechanic at deere said the new alt fit several styles and i could remove the vr and diode plate and install as such. did that and the dash lites still came on. apparently the original alt had the diode set internal, and the new style used the external diode set. put the external diodes on and wha-la.....all is good. cleaned up the old wiring harness, removed the butt connectors, scotch locks and the twist and tape connections, soldered, liquid lectric taped and sealed with heat shrink . the aux terminal on the alt feeds the charge and oil pressure lamp. heres some pics.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange.
