What exactly are you trying to do that you want a wiring diagram for?

These are pretty simple beasts, nothing fancy about them at all.

Best of luck.

When I push in what the book calls the ground button it blows
a 15 amp fuse. the tractor runs OK but will not charge the battery. When I disconnect the alternator the fuse does not blow. I had the alternator checked and it was bad. I bought a new one and have the same problem. The button I am talking about is the one you push in to start the tractor. My tractor and books are at my farm in Indiana and I am not there at this time. This is all the detail I can remember.

Ok. I think I got the idea.

First off, Russian is a VERY ancient language, and one that hasn't really changed with the times. As a result, words like "starter" just don't exist in the language. As a result they use the word that is the literal meaning of what the switch does, in this case "ground" the starter thus completing the circuit and making it turn over. The translatorobviously didn't know the proper English word to use instead.

At any rate, I suspect the problem is the starter is drawing too many amps and blowing the fuse. This also likely what killed the alternator too. The excess load ran the battery down making the alt. work too hard.

Best of luck.

Okay where's Murf and what have you done with him? Maybe he's floating off the coast of Florida--laptop and beer, eh? still in hand.

Murf, ol' boy--a fuse for the starter? There's not even a fuse for the solenoid--at least on my stuff. That's a new one on me.

And, an alternator working too hard blows it? New one too.

Sounds to me like a battery has been discharged and then recharged reverse-polarity or the polarity for the battery terminals have been reversed.

Not Florida Jeff, Lake Muskoka, Google it. Oh, and iPhone not laptop.

Me thinks you missed the part where he said it runs ok, how would it start with a reversed battery?

Lots of machines I've seen have a fuse on the switched side of the starter solenoid. Seems pretty normal to me. If the battery is low, as voltage drops current increases, if the big Rooskie solenoid is on the fritz also I could see it pulling too many amps.

Best of luck.

The fuse blows when the ground switch is pushed in. This only enables the circuit. The starter is engaged when you turn the key. Therefore it is not the starter. What is in the circuit besides the alternator, ground button, amp meter. This is why I need a electrical diagram. Can anyone help.

Sorry I can't help you with a diagram. But EW's right, these are simple beasts. If the Russians wire tractors like the Chinese, the starter solenoid circuit is not independently fused. But there is a system fuse, and it's not 15A. Mine's 30A.

The system fuse protects the entire wiring system as a whole, to include the starting circuit. So - on my tractors anyway - the only fuse that the starter solenoid circuit COULD blow, would be the system fuse. A bad keyswitch (or starter button) will take out a system fuse in a heartbeat.

If it helps, the typical electrical flow is Battery>starter>system fuse>ammeter>keyswitch>clutch interlock>starter solenoid>ground. If some fuse other than the system fuse is blowing, good chance that an accessory wire is crossed with a starting system wire someplace.

I have a 420AN, but not an electrical diagram. The button you are talking about is the ground button for the entire electrical. The ground from the battery hooks directly to it. In the engaged position (pushed in) the batteries (two 6 volts in series) are setup for a complete circuit for what ever you are wanting to do. If a fuse blows as soon as you push the button in, there is a short circuit somewhere in the circuit. If it is this 15A fuse, trace the wire from the side of the fuse that is not connected to the battery, and you should find your problem, ie a bare shorted wire, or defective item that is operated by that branch of the circuit. Hope this helps
