Eagle Starter Problem
I'm having a problem with my '95 Eagle's starter (Vision ESI 3.3; ND
starter). Any time it's damp out (it seems) the starter solenoid will simply click and not engage the starter, or simply give a little half hearted crank. I took it out last week and had it tested. It didn't turn up any problems, and I had they key it 15 or 20 times to make sure it didn't show up any issues. The Pep Boys tech who bench tested it mentioned he's had the same issue with his late 90's Intrepid, which likely has the same starter in it. He didn't come to a resolution either. While I had the starter out, I disassembled the solenoid and took the contacts out of it and cleaned them up They weren't horrifically corroded or anything, but I figured bare clean metal would get e better connection. I'm still having the same problem, and I'd like to try and resolve it before cold weather sets in. I'm thinking the next thing I'll do is replace the cables. I dont' think my battery is bad, because I just replaced it last fall, but I might have it load tested to rule that out. What's next? I see some notes on the solenoid contacts... Is there a way to know for sure whether the contacts are actually bad? |

VERY common intermittant failure in any vintage Nippondenso starter. |

I don't know all the proper names for the components of the solenoid, but if you're referring to the circular contact on the shaft that goes down into the solenoid armature and would complete the circuit across the two contacts through the case of the solenoid, then yes. I removed the shaft and cleaned up all the way around the edge of it with a wire wheel. I also unbolted both of the contacts that pass through the case of the solenoid, and did the same to them both on the contacts and on the threads. My thinking being that the cleaner all the contacts are, the less resistence to current flow there will be. I'm clearly not having any current flow problems in the activation of the solenoid windings as I can distinctly hear that throwing and going clack, and we're not talking about the sort of clicking that you get when your battery is weak. I read some other posts that talked about Toyota's using the same sort of starter solenoid and having the solenoid contacts available (whereas our wonderful Chrysler dealers wouldn't). I think I'm going to pursue that next since those contacts are probably relatively cheap. |

Mr. Ohm's Law works every time. > I'm clearly not >having any current flow problems in the activation of the solenoid >windings as I can distinctly hear that throwing and going clack, and >we're not talking about the sort of clicking that you get when your >battery is weak. <snip> >I read some other posts that talked about Toyota's using the same sort >of starter solenoid and having the solenoid contacts available (whereas >our wonderful Chrysler dealers wouldn't). I think I'm going to pursue >that next since those contacts are probably relatively cheap. <snip> If the contacts are both clean and properly making, replacing them won't do any good. The way to check them properly is to measure the voltage drop across them when trying to use the started. To do this, place a voltmeter across the battery connection and the motor terminal and then crank the starter. Nippondensos generally (but not always) have access to the motor side of the solenoid from the outside of the case, so you shouldn't have muc problem doing this. When the motor cranks and if the contacts are good, there should be as close to zero voltage drop at this point as possible. However, if there's a high resistance in the contactor circuit, you'll see a large voltage drop here. Also, when/in the motor refuses to turn, you'll probably see nearly full battery voltage here, so set your voltage meter (if it's not autoranging) to accommodate 12 VDC. If the contactor is good, you see little if any voltage drop and the motor STILL won't turn, you're looking at stuck/dirty/worn brushes, which on a Nippondenso, aren't that big a deal to change out. Brushes for these are usually available at better auto parts outlets...NOT the schlock chains, like Poop Boys and AutoBone. Good luck! |

I've bought contacts for a few Chrysler minivan starters, and they always tell me to bring the starter in to match the parts visually. Most shops that are in the business of rebuilding things don't like to sell parts, but these guys went ahead and sold me what I needed for well under $5. |

There's still one here locally and he will sell genuine, usually OEM, starter and alternator parts for a reasonable price. He'll also turn slip rings if you bring in the armature, or turn/undercut a starter or generator commutator. I do those myself on a small engine lathe here at home, so I don't need those services usually, but if I have a burned or missing commutator sector, he's got the stock to make a new one and will solder it in and turn it for about $25. He's going to retire in five years, and that'll be that for such shops in this whole area. |

Another common failure on NDs is worn brushes, so be prepared for this, as well. |

Just replace them. |
