Won't Crank, Won't Start. Any assistance would be helpful. Thanks!
Good Afternoon! Thank you all for having a forum like this. Hopefully we can get some answers to an issue we are having or at the very least, a direction to go in for more information.
Here goes: We recently bought a used/fleet maintained, 2003 F-450 Ambulance package, 6.0 Powerstroke Diesel. It has dual alternators and a total of 4 batteries (2 in the engine compartment and 2 in a drawer near the ambulance box). About 2 weeks ago, we were in a situation where the truck wouldn't start. I got underneath it and the wire to the starter was loose. We were able to get it switched out and get it started. We bought 2 new batteries and a starter - installed the batteries and waited on the starter...
This past week, we were driving and heard a pop/crash/bang noise and the engine's power was reduced. When accelerating, it wouldn't shift into a higher gear. My wife started to research forums and try to find something. We got it to a safe place to look under the hood and found that the turbo connection near the top alternator had popped off. As I was putting that back on, my wife noticed a burning plastic smell and I tapped the alternator bolt arcing it. A short while later, we were able to get it started and home but since then, when turning the key, it will not click, crank, or start. As of now, both alternators, the 2 batteries in the engine compartment and the starter are not installed.
We took the alternators out and had both tested. They both were reading over 100amps. We were told that maybe there is a fusible link that needs to be replaced. We are also researching other items that it could be. We have read a lot about the FICM (don't know if that has anything to do with this).
Please, if you can, what else is there we should be on the look out for. Where should we start in repair. What should/could we test at the DIY level without harming the engine and wiring?
