I have 1961 4106 with 8V71. The alternator is the block mounted,oil-cooled brushless type. It has stopped charging. We are snow-birding in the Southern California area for the month of January. We are currently in the Santa Barbara area. We will be in the Los Angeles area mid-month. Anyone have any suggestions where I might get repairs. |

Have you checked that it is the alternator and not the gauge? |

Can be a regulator or interlock problem but you really need a multimeter to eliminate that. Check if there is close to 24V on the field terminal - if not then it is a regulator or interlock problem Need to disconnect field wire and connect a 10 amp DC ammeter (most multimeters have this range) and check that there is about 5 amps current flowing - if not then could be an opencircuited field winding.(happened to me) If current flowing, check whether there is any voltage appearing at the tacho terminal. Should be around 12V. Check if getting voltage out on main terminals If not then could be multiple diode failure or shorted stator windings (also happened to me). [in this case check that oil flow is not blocked so that cooling has been too low.] At this stage there is little you can do with it until you get it off the engine. Could also be the gear drive has come off the shaft Been there, done that but in my case it was the pulley hub that fell to pieces. One day when Luke gets around to pricing my order, I might even get it all put back together but until then, I have enough solar to keep both lots of batteries fully charged. |

I would not remove the alternator until you are sure that that is the faulty component. It is REALLY heavy and if it isn't leaking oil don't disturb it unless it is bad. (it's tough to remove on your GM V drive but you wouldn't believe what a pain on a "T" drive bus Eagle). |

Dwight, I will be in LA from Sunday thru Friday, and would be glad to diagnose it for you for a cup of coffee. If its only a loose wire, or a stuck relay, which I feel it will be, we can fix it quickly. If it is an alternator, we will know for sure, and you can use Kyle's recommendation, or mine. George, Use the cell in the profile, please. |
