I have an Allis Chlamers d14 and CA, both are not generating electricity. Can anyone help me out, where do I start? When its running, I put volt meter on generator and there is nothing. Thanks
 
I am by no means an expert on this and someone more qualified and with a helpful attitude will come along soon, but I have had success by checking brushes which need to be replaced periodically. You need to do a little disassembly. start by taking a punch and making a pair of little pricks on the edge of the back plate and then on the side of the housing right next to them to guide in reassembly. Do the same at the front end. then loosen the four long screws that hold it all together then back two of them out one at a time. when you see how far they come out to release you see at what point you need to be careful about supporting it in order to keep it from falling apart. Carefully finish removing the screws and slide the back plate away and you will see the brushes that are held by springs against the commutator which is a part of the shaft. The brushes will be held by wire to the housing. some are held by screws and some by solder. my local hardware carries an assortment as do auto parts stores and dealers. Reassembly can be a little tricky in the part of holding the brushes back while sliding back together. I have overcome this simply by retracting the brushes with some light string then pulling it out when done. hope this helps.
 
Might need new brushes or the brushes might be stuck in the holders. Replace the brushes after sanding the holders so the brushes can move.Also a good idea to sand off the commutator and clean or undercut the insulators between the copper segments.
