I just converted my M1008 to 12V after thinking that my 24V starter went out. I wanted to go to 12V anyways to hook my winch up to the truck. Anyways I get the truck re wired thanks to friend Travis and the new starter does the same thing. It sounds like it is missing the flywheel, but it is engaging and the motor barely moves. The starter sounds like it needs to be shimmed, but after some research I found that these were designed not to be shimmed. I only hooked up one battery when going to 12V (Yellow top optima) and I tested the batteries that were on it before to see if they had enough juice (each had 12V). WTF is going on? I have 10 days to get this fixed before my trip to Moab and I am starting to sweat a little since I need to get this truck started and rolling to test out some stuff on it. Oh ya, the fly wheel has no broken teeth and the block seems fine where the starter mates. How much juice should I be getting at the starter? It's almost like the starter is getting enough power to turn the engine. It can be turned by hand though...... I need help please!!!
trun the engine around a few times by hand, and then retry. beware, this can blow a starter to shreds if it does the bang stop theory.... have had quite a few act that way, and it turns out that they are partially hydrolocked due to cracked heads, take it down ,and the engine will bar over by hand at the flywheel wit ha prybar no problem, stick the new starter in and it will goa half turn before stopping completly or slowing down.......
Put a fluke meter on the batery when you try and start it and see what it drops down to. A battery can show 12-14 VDC until a load is put on it then it will drop way down. Test it even if it is brand new. The battery in my wifes brand new car just went bad a few days ago. Are you sure that the starter doesn't still need dual batteries set up in series instead of parallel? Keep us posted on what you find out. waytogo
I have one question for you. What do you think would be the problem if the starter wouldn't spin fast enough with your Cummins if you only had one battery hooked up? Your 6.2 is a bigger motor than your Cummins. It's larger, 6.2vs.5.9 and it has a bunch more compression because it's not turbo'd. Optimas are nice batteries because they can sit sideways, but thats all they have over a regular battery. Hook two up like factory and it should fire right up.
He said he only hooked up the one battery. So 12 VDC would be what he would be reading. By the way, if your truck was a 24 VDC system did you remember to switch out the altenator when you switched to 12 volt? Just asking.
Seriously are we being that freakin anal. Do I need to give exact readings on the numbers? I work on diesel generators every day. If a battery has 12.6 vdc or 12.2 vdc, it has 12 volts, I don't usually include the point whatever. Tomorrow I will test one of the new optima batteries and let you know exactly what the reading is. If I remember right, I suggested that he test the battery to see if it is good.
he wrote 12.0, then you guys repsonded it was fine, i then argueed that 12.0 is NOT a good battery.....
I was a little harsh with my response testerday. I got to deal with some idoits for about 6 strait hours yesterday and I was in a bad mood. Bottom line instead of listening to people argue over what a dead battery is, test the battery, hell test the starter, check connections and make sure every thing is hooked up poperly and go from there. Hope you find the problem and get to Moab. Let us know what was wrong.
Hey guys I forgot I posted over here when CK5 went down. It ended up being a faulty ignition relay wire to the starter. I guess it was grounding out or something and would not get all the power to the solenoid? We tried jumping the terminals on the starter after I exchanged the first one I bought. It cranked over fine. Since we had gone through all the other wires we figured it had to be the ignition wire. Wired up a push button start that fit right in the cigarette lighter hole and all is good now. My friend has an 02' Dodge with a Cummins and has ran one battery for the last 2 years since he bought it that way. From what I have heard 2 batteries will only give you more starting/cranking time as opposed to one battery. I have cranked it over 20 times since yesterday and it fires up within 2 seconds. I guess I can be the test bed to the one battery theory:stir:
Maybe if you have a fresh high powered battery it will work. I work around a lot of equipment, and when you remove a large amount of the stored electrical capacity from something that is designed to use all of it, it will catch up. I tried running a big single battery on a DT429 International engine. Yeah, it would crank over fine, but would tire quickly. Forget changing the fuel filters, loosing fuel prime, or a cold morning because that single wasn't going to provide the adequit amperage storage to be able to continuously crank over the engine outside of a simple "bump and start." Not to mention it's hard on the starter, solenoid, altenator, and very hard on the battery running a single in a system designed for duals.
send some pics of Moab once you get back and glad to hear is now working fine but I would recomend two batterys for things like lighting,winching or playing the radio at a camp fire all night long.
