I belive my silversides electrical grimlens are being caused by a bad voltage regulator. I would like to put a one wire rig back on it so I'd like to have a clue what I need to tell the parts man.
Also anyone have an idea how to keep my starter selenoid from freezing?(ice storm here a couple weeks ago)
Thanks in advance. |

you need a G.M. one wire alt.....available at MANY parts houses....if....you are negative ground |

i went thru numerous problems with alternators until i had a Freightliner dealer install a lesse-neville 130 amp . |

Not exactly a block heater, at least as I think of 'em, I've got no freeze plugs. I did put in a CATs tank heater that I'm a big fan of. I like stuff I can see working and this thing will steam the moisture off the out side of it within 30 sec of plugging it in. Leave it plug in 24 hours and you can feel the difference when you open the engine compartmet, it's great.
I thawed the selenoid with a little butane torch this afternoon, she wouldn't crank but I just had it plug in about 10 min so I didn't expect it to.
And yup I've got a negative ground, thankfully. |

Leece-Neville 150 amp single wire alternators are a commodity item at most repair depots. The Peterbuilt supply not far from where I live have them new in box in stacks on the sales floor at $140 each out the door with no core charge. Amazing what "Made in Mexico" does to the price.
Do keep in mind, internal regulator equipped alternators generally aren't adjustable, so you're stuck with 13.8 to 14.2 volts out, depending on tolerances. Many external regulators are adjustable. The difference this makes for you depends on the use of the coach - for short test runs on an infrequent basis you'd want to set the voltage higher to charge the batteries, and for long trips turn it down to keep from boiling them over.
If your 3751 has a good working alternator (test by bypassing the regulator to provide full power to the field) then you'd be better off keeping it and getting a new regulator. If it still has its original generator, then you'll definately want to change it over to a newer alternator. |

The problem with one wire alternators is the high rpm necessary to excite the field to make it charge. I have one on a fire truck and it is a pain.
Internal regulator type GM three wires are so simple to hook up and charge at a very low rpm. They are also very cheap and available at every auto supply store. However, I'm not sure they have enough capacity for your use. |

the one wire G.M. alternators are available at parts stores up to 140 amp |

I wonder If you could get a 12 volt Alternator changed over to 24 Volts, since we are running only lights and no Air they would charge the Batteries |

Not all 1-wire alternators need a high RPM to excite or give high charging output. It all depends on the model.

ALL the ones I've ever had ...just took a real short step on the accelerator...but....made a mistake once...started the truck...pulled ALL lights on & flashers..because I was being unloaded in the MIDDLE of the street...forgot to give it the one RRUMM..that it needed to excite...&....ran the batterys completly down... |
