LS180 Lost all electrical...

[mfyock]

Mike10, this might be one for you.... I have an LS180 that was running fine and all of a sudden the engine shut off. Lost all electrical. No dash,lights etc etc. I have battery voltage over to starter. From the starter the line runs to the rear fuse panel right? I didnt get a chance to check voltage there. I suspect I have a corrosion or broken wire. When I first got the machine a few weeks ago the headlights wouldnt work. No power to the relay. I unbolted the main fuse box and was poking around and all of a sudden I got voltage to the relay and everything has been fine since then. Is there any way to easily repair the wiring to the fuse block? If I remember correctly the wire was crimped onto the metal that goes to the incomming side of all the fuses.

The power flow starts at the battery and goes to the starter. From the starter it goes to one of the large posts on the start relay under the fuse panel. The outer relay. From there it goes to the preheat circuit breaker in the fuse panel. The cirucuit breaker is the round one. The power to the key switch does not go through this breaker. The terminal, on the preheat circuit breaker, with the power coming from the start relay also has the wire that sends power to the fuse block in the fuse panel. This wire supplies power to all the fuses in that block. The 15A breaker sends power to the key switch. Since you have no lights on the instrument panel, which uses the 5A fuse, I think your problem is between the starter and the fuse block. You can pick any place in this portion of the circuit to start your testing.

Thanks Mike. I was on the right track, but was having trouble last night tracing wires in the dark, in a field, with the boom down. Why dont they ever break down next to the shop? You have any good tricks for running a new hot to the fuse panel? If I remember correctly its not easy to splice into the back of the panel.

Here are the part numbers for the fuse block. This does not come from the skid loader line but should be the same.
245435c1 4 fuse housing
506498c1 10 gauge bridge connector. One wire attached to this bridge will power 4 fuse slots. Or you can separate as needed.
225111c1 14 gauge connector for fuse
225112c1 10 gauge connector for fuse
You can check with your NH dealer to see if he stocks them. The housing and bridge connector will be no problem for him to order for you but the other terminals require the dealer to take a large minimun number that he may not want to stock or he might make you take all of them.. You may have better luck at the CaseIH dealer since they seem to stock various wire connectors. Having the option to order wire connectors is something new in the NH line These numbers actually come from the Case side. If you have no luck, we do stock them.

Interesting...I have found the same thing with the electrical connectors. Went to the NH dealer a few years back and they didnt have any electrical connectors. Went across town to Case and they have drawers of repair connectors. So could I find these part numbers in a case online parts book? What model would I use? A 420/410?? I found the issue this afternoon. No voltage to the preheat breaker terminal. I wiggled the wire and got voltage. This machine had been very odd with electrical issues. It sat for a while with a blown engine down near the gulf of mexico(corrosive enviroment). When I got the machine none of the lights would work. I had to clean up electrical connections at the relay. I also had to take EVERY light bult out and clean the connections. I also cleaned all the fuze block connectionsThe wierd thing is the connections didnt look corroded. They werent all green or anything. Just a little bit of gray haze. I NEVER would have guessed there was enough corrosion for the contact to be not work.

I do not know what model Case product uses these parts. Until the last few years NH dealers did not have access to many of these connectors or at least did not know what was available. Part catalog breakdowns rarely gave electrical connectors and the terminals part numbers. It was procure locally item.
Did you have power at the start relay under the fuse panel prior to wiggling the wire?

Yeah, had power at the start relay. It was the ring terminal at the preheat circuit breaker. I gave it a little wiggle, and the list pump started humming. As I wiggle it I can hear the pump hmm change a little. I quick lifted the boom up, and locked it. Didnt get a chance to clean wires, or replace yet....
