C160 passed out once , then died.

Hi guys,

Sorry I haven't gotten back to you sooner. I was able to get out and get a new battery, the old one checked dead..0 volts. It was kind of old so I got a new one. Put it in and away she went. Ran great, took right off...But..no lights. It was getting late so I figured I would get back at it today. Went out there and turned the key and nothing.  So I figure I have a short to ground in the lights. I'll try to get back out there in a couple days and go from the switch to the lights and look for the short. I do not recall seeing an inline fuse in the light wiring. If there was a fuse it would have simplified things I guess. Anyway, I'll get back to you in the new year.;

 

Thanks,

Bob

There are no fuses on older Horses. 

When rewiring several of us add them in. 

 

I trust you disconnected the battery and put it on a charger?

 

[Bob Nakon 55]

I didn't put the charger on it Eric but I disconnected the battery cables.

If that battery gets a decent charge it might be saved.

You should, as soon as possible.

 

Running a lead acid down to zero charge severly shortens it's life.  The sooner you can get it charged back up the better.

Keep in mind that it's got a shorter life now though...

I was just typing the same thing.

 

In addition, a dead battery can freeze and destroy it completely.

Ok, so I found that one of the wires to the light switch is burned in half. Funny thing is it doesn't look like it touched anything to ground it out. It definitely burned in half though so I have to track the wire to the lights, may find something along there. So I disconnected both wires to the switch and now it won't turn over with the key. Jumped the solenoid and it turns over but no start. I guess the current to the starter must run through the light switch? Like I opened the circuit or something. Weird.

[ebinmaine 70,810]

Current to the starter solenoid should NOT run through the light switch.

The C-160 has a fuse in the light circuit. The lights should be attached to the accessories tab on the ignition switch.

Thanks for posting that diagram Bob. 

I've had at least 2 C160s with no fuses anywhere. Most certainly could have been PO "fixed". 

Now ya got me wondering about the 2 C160 Tecumseh engine tractors here. Neither appears to be modified. 

I'll check those out sometime...

Both?

Which both?

Where did you disconnect?

Right at the switch?

 

IMHO it would be in your best interest to seriously consider a full rewire.

No fuse in my C160 either even though the diagram shows one. Light switch has nothing to do with cranking.  Ammeter would drop power to the key switch. PTO, clutch pedal switches will cut power to solenoid.

I need all my fingers and toes to count how many times I've seen the ammeter or ammeter connections do this on a C series tractor.

I’m convinced my K341 machine’s connections just get rattled apart by that beast of an engine.

Yours wouldn't be the first one that's happened to.

So Eric, I disconnected the wires from the light switch. One of them was burned in half, the other was intact.  It appears that the wire that disappears down underneath headed for the headlights is the one that burned. The mystery is: why did the headlight switch kill the ignition?  Where does it go? Must go to the coil eh? Where else could it go with enough authority to shut down the tractor. It's plenty cold up here so I may wait for a 45 deg day to attack this. It is pretty weird though.

[ebinmaine 70,810]

Certainly is VERY odd.  

 

Like Mike wrote...

I'd be at a point of not trusting the wiring on that. 

I'm not a big believer in chasing electrical gremlins or "run-to-fail". 

 

Maybe some of that tractor's harness is ok... But I'd change ALL of it.

I bought the tractor 1½ years ago and it seems that the person I bought it from was less than honest about it. The guy was not a Wheel Horse man. He was just selling it to get the money. I was looking for a 160 for 2 years but no joy. It is a strong runner and the power of the 16 vs my 120 is amazing. I guess I'll just fix what fails and give it plenty of tlc.

To some extent I agree. 

 

What I mean by that is ... You don't necessarily need to wait for things to fail before they get fixed. 

 

Go down through this thread:

 

 

As you'll see there's a LOT of information in the list.  

 

Check the list.  Check the tractor.  Repeat. Repeat. 

 

You'll see where the parts are that may need attention now vs later. It'll give you a better idea of what needs to be done in your own rig.  

 

Pay particular attention to the sections on cleaning. That's absolutely paramount. 

 

Keep asking questions and keep us posted.  

[rmaynard 15,932]

The lighting circuit has nothing to do with cranking as Mike said, unless there was a short that drained the battery.

 

For the record, I've had 2 C-120's, and 1 C-160 all parts machines, but all with intact wiring. Each one had a white wire with an in-line Buse fuse holder coming off of the ACC tab on the ignition switch, going to the light switch on the dash. Each one was identically wired so it must have been factory.

 

Just sayin'
