Eagle 10 (204.181.141.86)

I have a 1984 Eagle 10 that has a 350 amp Neihoff altenator on it and I want to replace it with something else. I still have the road heat and A/C motors that work great and I want to keep them. Question??? How many amps does each bus heat motor draw? How big of an alternator do I need to cover my needs? What brands would work? If you have made the change over, let me know how it worked out. Thanks! |

A/C condenser fans draws about 85 amps, and the evaporater fans draw 35 each. Leece- Neville makes a 325 amp that should work well. About $3K new without core trade. Yours should be re-buidable for about $850 to $950. This is the problem with keeping the stock A/C system. Wait 'til you have to put 20 lbs of Freon in it after a seal blows. Cheers? ...JJ |

Jayjay,
I don't use the A/C so is not a concern. I only want to keep my over the road heat motors working. Do you know how many amps each one draws?
Thanks. |

Is there any way you could crawl down there and see the motor info stamp plates and find the amp draw? If you plan on keeping the two big blower motors for the bus air/heat, I remember when I pulled mine out they were huge. I also pulled out the driver's air/heat blower. It was big but not near as big as the air handler motors for the heat/AC.
From reading your post, it seems you will eliminate the condenser fan motor, so bye bye to about 85 amps. If the rest are kept, then you still need a big alternator.
I still have my Neihoff in my Eagle 10. It is merged with the house bank to run a Coleman rooftop down the road.
When I turn on the Coleman I get about 13.2 volts at the alternator output, and about 12.7 to 12.8 at the inverter at the end of 22' of 4 ought cable. So, it can barely keep me in the black.
I figured it takes about 180 to 195 amps to run the Coleman.
It also lugs the engine down. I can hear it drawing the horsepower from the 6v92. Consequently, I usually use the Genny and run all three AC's and keep the coach meat locker cold while running down the road.
A bus mechanic that worked on my coach for me advised me to get rid of the Neihoff because of the high costs of repairs. JayJay's post verified the cost. It will be expensive when that puppy dies.
If that happens, I may get a couple of big alternators and belt them together to get the output I want, but for now I'll stay with what I have.
If you are wondering what I'm using for driver's heat, I bought a Danhard heater from JC Whitney and mounted it in the dash near my gas pedal. It is plumbed to the Eagle heater lines. It works well for me, but in hindsight, I may have tried to modify the layout of the old Eagle driver's heater to suit my needs.
My coach heat is now povided by a Webasto with an engine heat exchanger. I love it. It scavenges heat off the engine while running down the road and also provides hot water to the Sealand water heater. It also is a block heater when the Webasto is used as a furnace.

I will stay with my Neihoff alternator as it is working fine now. The problem was the voltage regulator. This is my second one in 16 months at $300 each. I will continue to look for other options in case I have another problem. Thanks for the come back. |

Just for information, where did you get your voltage regulator? In case I need one.

The bus company ordered the regulator so I don't know where they got it. I think they ordered it through a local alternator repair shop. The problem I have is finding someone who will work on the Neihoff alternator. Most shops up here in Maine have not seen these as there are very few Eagles in the state. I only know of 4 or 5. There are only about 12 or 15 conversions in the whole state. |

Maybe Neihoff directly?? They could refer you to a dealer that works on them. Also, Jefferson Truck in Oklahoma City 800-813-9367 ask fo Norris.
may have parts or leads on service.
They have most of the Eagle parts in the country.
