Chad, Ive not messed with many Allis, but can offer some generic advice which may or may not be helpful. Prior to suspecting a starter problem, I would first eliminate of its a cable or ground or battery connection problem. Thennnnn nnnn if its a starter switch or relay problem instead of the starter itself (see below) 1) Althoug you indicated you did so, to be safe, I would Remove,,,,, Clean n wire brush,,,,, ,and Reattach each n every battery n stater n switch n ground connection. If the ground happened to be on any rusty sheet metal seat or battery box, I would attach it to a good solild clean frame member. 2) Are you sure the battery is good and charged??? Has it been Load Tested by a battery shop??? Is there electrolyte above all the plates and no cells exhibitign any gray or milky color??? Maybe try a good substitute battery n see what happens?? 3) SWITCH OR SOLENOID PROBLEMS If you turn the lights on and try n start her, do the lights dim wayyyyy y down when shes trying to start????? If so I suspect more of a starter problem then a bad starter switch or starter solenoid. Also, if the starter gets realllll hottttt ttttt I suspect the starter. If when you try n start her the lights dont dim very much, I suspect a possible bad starter switch or starter solenoid. If it has a mechanical push to start starter switch (mounted right on starter with an activation rod) and the starter dont get hot or lights dim bad when cranking,,,,, ,I would remove the switch and inspect BOTH the copper post on the starter and the switches washer/contactor for burning n pitting and being all carboned up !!!!! !! If the switch is burned or pitted or carboned up I would replace it. If the starter post (if it has one) is all burned n pittred you may get by with a cleaning n wire brush and light filing to get her to work again, or it may need repalced. If it has an electric solenoid starter switch, you can try to use jumper cables to by pass jump around it (battery side to starter side) to see if it cranks better then. CAUTION thats a high current jump so use care!!!!! !!! FINALLY, if the battery is good n well charged,,,,, ,,,if all battery n ground n starter n switch connections are all good,,,,, ,,,if the cables are all good,,,,, ,if its NOT a starter switch problem or the starter post under it is NOT burned/pitted,,,,, ,,,and especially if the lights dim way down and/or the starter gets real hot,,,,, ,,I SUSPECT A BAD STARTER. (worn brushes or shorted or dragging armature or worn bushings etc) NOTE This assumes its not mechanically sticking (check that out) its drive gear teeth into the flywheel and the engine isnt siezed up (insure that)????
