we got a new to us 90s ottawa yard truck with a cummins 6bt engine (i know this is forestry equipment forum but most all appentice and barko knuckle booms use the cummins 6bt so i firgured i had a better chance here ) it has been hacked bad in wiring ,,,, can anyone help me with the 3 screw on stud wire alternator wiring diagrams not the plug in, right now it has 2 wires running back to the battery and i know that aint right ,, the batt terminal on alternator is empty no wires hooked too it.. i tested the wires and im getting 13.8 on one wire and the terminal marked batt i get 6 volts the other is a ground i think i really didnt get a chane to test it got called away for a breakdown.. if needed i will post pics of alternator and how its wired now
