What should be the minimum output amps I need to run the Saturn EPS? Sent from my VS985 4G using Tapatalk |

Yepper. I think that's my problem with it going on and off. Thinking of getting a 75 amp alternator. With a 6000lb winch I should have considered my amperage. Never had to worry about that with my 4x4's. Sent from my VS985 4G using Tapatalk |

I would also like to figure what the amp draw is. wanting to fuse my newly installed power steering Terry |

I read some where after posting this, the EPS has a max of 62 amps. Hard to believe. I have a 30 amp fuse. It only has blown twice but I had a loose wire. Sent from my VS985 4G using Tapatalk |

Make sure that the coil is getting enough current while cranking. 3) After the engine is running, a fully charged battery will usually supply plenty of current for surge demands of EPS motors, electric air pumps, lights, amplifiers,etc.. 4) If you think that you will be turning the steering wheel at the same exact time that you are turning on other accessories then you could damage the charging system?? If this is the case, then there should be a quick-blow fuse between the alternator and the battery. 5) Any fuse that blows between the battery and any accessory, should first be replaced with a lower amperage slow-blow to fix the problem. If that blows, only then do you increase the amperage rating of that circuit's fuse (in small increments). 6) When the EPS motor first turns on and is under load, the surge of power drawn is large. It is hard to say how heavy of a cable to run, but always go one or two sizes bigger. This offsets any future occurrences with problems like poor connections, faulty motors, faulty motor drivers, etc. |

That makes sense jimp but my Explorer has the same size battery as my Expedition. The Expedition has a high output alternator due to all the electric gizmos. The Explorer doesn't have an high output. I'm believing that there is more than matching the battery. My battery is a 500 cca deep cell. Sent from my VS985 4G using Tapatalk |

Sent from my VS985 4G using Tapatalk There is more to it than matching the battery and the alternator. The baseline spec is to match the alternator to the battery and then go from there according to how many more accessories that you are running continuously. Too much alternator supposedly shortens battery life due to internal plate degradation. |

What's your amperage Dan? Same as Eric's? Sent from my VS985 4G using Tapatalk |

Those Honda alternator are probably factory. I would like some vw owners to chime in. Sent from my VS985 4G using Tapatalk |

| Post subject: | Re: EPS Amps |
if im reading all this correctly, you are asking this question because your power steering quits at times? also did you buy and install the adjuster kit off of ebay that your "supposed" to use with it? |

| Post subject: | Re: EPS Amps |
Yes. I bought the kit. Even if the EPS didn't shut down I think I need to upgrade the generator. Under certain circumstances at night I am way under on amperage. I don't want to damage my deep cycle battery. Winch (at 2000lb pull) 132 amps, LED light bar 2 amp, 4 lights 3 amps, EPS 20-30? amps, tail lights 2 amps. No doubt generator is taxed out. Problem waiting to happen?? More so than not. Sent from my VS985 4G using Tapatalk |

I copied this off facebook but it didn't have the whole description in the picture. sure would be nice to read the rest of that part  didnt the ebay part come with these instructions

Yes. It came with instructions. I also didn't do the on/off switch like he said. I have it wired to the ignition instead being seperate. It probably needs the engine running before power going to the EPS. Sent from my VS985 4G using Tapatalk |

You definitely need an alternator, I am running EPS with Fuel Injection on A/C vw with 55 amp alternator and it is working well. I am using the 70 amp fuse that came factory with the Saturn EPS, Good Luck |

Update. I installed a dedicated on/off switch and added a 75 amp alternator. EPS works great now. No issues. |
