Wiring issue

I just rewired my 1946 2N and when I turn the switch on ampmetersmokes,so I reversed the wires and it smokes again and needle pegs both ways.
Can someone advise me on this.

sounds like one of those wires is going to ground, neither side should be grounded. power should pass [u:53a493cc42]through[/u:53a493cc42] the meter.
Others will pipe in soon, do a google for JMOR wiring diagram.
 
Tom........yer center reading amp meter don't care, 6-volt or 12-volt, it just inticates which way the BATTERY electrons are flowing. Convention sez: plus (+) means electrons going INTO the battery fer storage; minus (-) means stored electrons are being used to run sumptin'. Iff'n more electrons are being used than being generated, then you will soon haffa DEAD BATTERY. As fer yer smoking AMP meter, yer SHORTING sumptin' to ground, taking ALL the electrons OUTTA the battery; OVERHEATING the insulation and making it burn. BTW, starter don't care, 6-volt or 12-volt; positive (+) or negative (-) ground; ALWAYS turns the correct direction to to start yer engine, 12-volt just makes 'er turn FASTER. There are some OBSCURE reasons fer positive (+) ground. Hazza tadoo with yer sparkies. Modern sparkies (2017) are so much better than the original 1939 sparkies. Recommend AutoLite 437's gapped 0.025.......HTH, Dell, yer self-appointed sparkie-meister
 
Ok,I looked at the jmor diagram is my starter floor button not a solenoid?Do I need to use a solenoid also.Ive looked at several diagrams for the
46 2N so I'm confused witch one I need to use.I bought the tractor with no wiring so I'm starting from scratch with 12 V conversion.

he neutral safety start button is not a solenoid & not a switch, but a mechanical link to a start switch which is located at front of steering assy , below battery. Two battery cable size terminals on switch, one from battery and other to starter motor.
 
You wouldn't be the first guy to attach the wires to the meter mounting studs instead of the meter. Check that out. Then, Google " wiring diagrams JMOR". Find the one that fits your tractor. Make 100% sure you have it wired correctly before you try to start it; the next time, it might be more than an ammeter that burns up.

Your tractor does NOT have a solenoid. It has a starter switch. Get the correct diagram.

Changed a couple of wires it now turns over.I have discovered I have no continuity at foot switch on motor side but I can jump it.

hat can I say? Don't know how it was wired or how you changed it??
 
"is my floor button not a solenoid?" No it is mechanical lever which closes the starter switch. See JMOR's pictures elsewhere in this post.

"Do I need to use a solenoid " No the push button on the trans cover is connected to the starter switch on the front side of the steering column. It may be worn out.
 
I replaced the mechanical start switch, problem is it will turn over with the key on or off.What have I done?I picked a diagram and still an issue.

it will turn over with the key on or off."...just like it was designed to do!

it is working correctly. the starter should engage and operate if the starter button is depressed, key on or off makes no difference, except that the engine won't start (or shouldn't) in key "off" position. but it will continue to turn over as long as the starter button is depressed and there's enough juice in the battery.

(quoted from post at 10:57:15 04/28/17) Put some gas to it fired right up and charging fine.
Thanks everyone
Tom

You're welcome. Glad to help
would have said the same, Bruce, but he never did tell us what wires he changed to fix the high current smoke problem, so..............? Less than happy to spend all the time with someone that does not even have the courtesy to give feedback/closure. :(
 
:cry:

So sorry about your Amp Meter. I worked as an electronic technologist most of my life. You most likely getting more current flow through the meter that is was built to handle. The meter is now probably damaged beyond repair.

To trouble shoot your problem you really need a multi-meter measure the voltage, current and resistance. It especially handy to confirm your wiring by checking for continuity. As you probably know wire has a low resistance to current flow. A wire from the battery to one side of the amp meter with the other side of the amp meter connected other side of the battery will cause the meter to smoke. There should always be a load (resistance) between the meter and the battery one side of the battery terminals. The load less than .3 ohms connected across a 6V battery will peg the meter. For a 12 V battery you need a .6 ohm. load.

Hope this helps
 
Sorry JMOR,I used a wiring diagram from just 8n and it showed positive from starter to one side of the ammeter the other side to negative
battery post.Well,that's wrong,for me anyway.So upon advice from this forum both sides of ammeter are hot that's the wire I changed.
Tom
 
Don't worry too much about it. I'll get over it. :) Thanks for the response. I am going to guess that you used the voltmeter diagram to wire up the ammeter. There is an ammeter diagram too. At least it all ended well!
 
JMOR,not sure what your problem is.Here is the diagram I used,hope your happy.

don't have a problem, rather trying to figure out where you went wrong & now you just confirmed my suspicion..............you used a Voltmeter diagram to connect an ammeter & that does, as you found, make smoke. Have a nice weekend & I do appreciate the feedback.
