    Newbie from Moody tx

    So guys I have this lincoln Sae 300 1976 f227 code 6890 serial #A671748 ! Here about 2 months back I was welding with it after dark had the doors up and the wife said it was throwing sparks everywhere so I looked it over found it had bare wires from being dry rot and cracked and flaking apart! decided to replace the wires one at a time being ever so careful to not break or damage any other coils or parts and making sure I got all the wires replaced and put back where they came off from. Then I figured while I was renewing the 5 wires from the generator barrel to the panel I would go ahead and repaint the machine. Well its all back together and running but I can not get it to arc and weld! I have power to run the grinder from the 115 volt outlet and sparks from the welding leads when trying to arc to weld! I have done the muiltimeter hop checking ohms cleaning all connections ensuring i have good connections for the leads and scotch brighting the armature and checking the brushes and holders. During the repainting process
    I cleaned up and repaired the frame and there was a bolt welded the the generator mount where the battery negative wire was connected it broke off during tear down to ready for paint figured instead of putting it back there I would attach it to the frame instead would this be the culprit of not getting and arc?
