CAV control box issues and Fuses....

The generator is getting 2 or less volts on field current and not putting out any voltage. It does put out voltage if I jumper B+ to Field for a moment, upwards of 20 volts (I don't do that for very long).


Two, in the process of troubleshooting this I managed to blow the main fuse and we have no more. Anyone know where I can get the CAV type 50 amp main fuse from? It appears to be lead, I was thinking of making a replica out of 1/2 the thickness .005 brass sheet and then tinning it to see if that would work (start smaller). But, I'd rather use a proper thing and not have the risk of frying wiring I spent so much time installing. So, does anyone know where the CAV clip on fuses may be had from?

Ryan,

If you go to the workshop manual it explains the tests to be carried out, one like Lynn says, is to motor it over, a good basic test. Could be a dirty commutator, or sticking/worn brushes, or presence of oil or grease. As for the fuse, don't think it is lead, should be a thin aluminium, easiest thing is to source some fuse wire of 50 amps rating.
