Okay need help bad. Reply #30 – November 12, 2008, 03:29:25 PM Quote from: Birdman;242710 OR it could mean that the starter is only able to grab the 6.5 volts because the ground is bad. If there is resistance, the amperage should go up, and the voltage should drop........I'm such an electronics NEWB:mullet:Huh! I don't know how to respond to that except to say that's wrong. Since you are referencing the meter to the negative battery post, the ground circuit between the battery and the starter is out of the picture for the measurement you are making.Resistance is the resistance to current flow. Amperage is the amount of current flow. That's as far as I am going to go into DC electricity 101. Quote Selected
Okay need help bad. Reply #31 – November 13, 2008, 10:00:29 AM Like I said, Newb :)So it was not the ground wire. We replaced the ground and the solenoid, and it still grinds. We disassembled both starters.....the newer one and the older one look like they got awfully hot inside. The new one would barely spin...the older one would spin and kick out, but it didnt sound quite right. We tried using parts from both to make one good starter, but that one did not work either. While the brushes on the old one were shot, the windings on both looked VERY suspect.So here is my theory, and please let me know if it is right.The ground WAS horrible. because of that, it caused the starter to heat up ( the newer one) and it killed it. The older one may not have been good from the word go. Does that sound plausible? It looked as if the ground wire got pretty hot at some point....Not sure why, but it was definitely shot.

Okay need help bad. Reply #33 – November 13, 2008, 03:11:38 PM ... sounds reasonable as anything i can think of. can't never have too good a ground. :) Quote Selected
Okay need help bad. Reply #34 – November 13, 2008, 04:54:20 PM That ground was something else...green corrosion all over near where the fuel pump ground connects to it ( what a stupid freaking design!) and bolts to the frame. It also appeared that that cable had somehow gotten hot at some point.... right near the corrosion. SO... could a bad battery to engine ground cause the starter to heat up, shortening its life and killing it? I'm trying a new starter (no reman) on the truck on Saturday. Quote Selected
Okay need help bad. Reply #35 – November 13, 2008, 05:12:44 PM i would consider a new bat. depending on how it tests. id go ahead and get a new starter along with a new ground cable. clean it all up and hopefully you would be good to go. Quote Selected
Okay need help bad. Reply #36 – November 13, 2008, 05:37:49 PM http://www.partsamerica.com/ProductList.aspx?parttype=123&ptset=A&searchfor=Starter Read about the Palladium starter on this page. It seems the resistance can be pretty touchy for this vehicle. On a side note, I had a 1987 Bronco II 2.9 and in less than 150,000 miles, it had 3 engines, and 2 trannies installed, and a new ECM, and then the wiring caught on fire up by the solenoid on the pass. fender and firewall. I put alot of money into that lemon, and then put a 1966 bronco driveline under it before selling it. Moral is: Expect problems, lol. Quote Selected
Okay need help bad. Reply #37 – November 13, 2008, 05:38:59 PM Yes a bad ground will cause the headaches you have.It's been known 1 out 3 rebuilds are bad. Thats why there selling new parts cheaper than rebuilds. Quote Selected
Okay need help bad. Reply #38 – November 13, 2008, 06:19:34 PM HAvi...Yeah I saw that as well. I'm wondering if a lot of these rebuilds are that sensitive. Regardless, if the core problem was resistance in the wires, I now know that all the cables are correct. I replaced them all. So the next step is the starter. It doesn't surprise me that you had electrical problems there. its a real stupid design. They also changed the head design in 89, making the heads less succeptable to cracking that the early 2.9s were known for. When the truck is running, its got more balls than my buddie's freshly rebuilt 4.0 exploder :shrug: The good thing is that this engine seems to push start ultra easy. W'eve had to do that a lot lately! LOLI ahve a couple of taillight grounds to fix and a bit of cleaning to do (along with fluid changes) but is the gd'n thing would start on its own, I'd be golden. I 'm probly going to change out the shocks before teh snow hits too bad too, just in case. even though it looks nice, its still just a winter beater.Shame: The battery tested out okay, it was just a bit low from sitting so long. The alternator puts out the right voltage too, so that is a relief.Kits, It really depends on the rebuild. The liftime ones can be okay for starters, but I'd never go with anything less. Alternators are brand new or junk IMHO. Quote Selected
Okay need help bad. Reply #39 – November 17, 2008, 06:29:56 PM IT RUNS!!!!!So after replacing all the cables, we put a new starter in it.It starts and runs without any grinding now!Pics in the User Rides Section to come soon!:burnout: Quote Selected
