Greetings,
I bought an old 580CK (1967 vintage - originally with generator) last year. The person from whom I bought it had installed an alternator to replace the original generator, but had never hooked it up. Much of the wiring was missing and most of the gauges on the dash were missing. Plus when I checked it, the external regulator was not working. So, I opted to replace the alternator he had on it as well as the regulator with a re-manufactured Delco-Remy 10SI series alternator with an internal regulator. It is a 63 amp alternator. Because the wiring was so messed up (as well as much of it missing) I decided to re-wire the whole tractor. With regard to the alternator, I wanted to replace the ammeter with a voltmeter and install a charging light. I am essentially creating a whole new schematic and wiring scheme. however, I am not an expert by any means in designing alternator circuits. Here is my question. The field wire (pin 1 on the alternator connector) needs to run from the alternator to the "ON" side of the ignition switch as I understand it, and the charging light needs to be in series on that wire run. The thing is, I have seen schematics where there is just a light wired in series, and also circuits where there is a light and a resistor (wired in parallel to each other) between pin 1 on the alternator connector and the ignition switch. Does either approach work, or is the added resistance necessary for the light to work properly? Is the absence of both a light and a resistor in the wire run a problem for the operation of the alternator? What type of light should I use? I have seen LED type lights at the local auto parts store that will fit in the existing hole in the dash.
Next, the sense wire (pin 2 of the connector on the alternator) is then supposed to be run essentially to the positive side of the battery so that the alternator can sense the voltage drop on the system. My plan was to run that wire from pin 2 on the alternator to the battery terminal on the ignition switch. Is this an acceptable approach?
Finally the battery terminal on the alternator will get connected to the battery terminal on the start solenoid.
Does anyone see anything wrong with this approach? I have drawn up an electrical schematic which I could scan in and attach if it would help.
