johnmonkey Posted October 6, 2004 Posted October 6, 2004 hello, I finally got my scrap yard 3410 running, I am going through the sea trials right now. 3 questions. 1) I have a white wire that comes off of terminal "D" on the starter switch, where does it go?? I do not see a terminal "D" on the wiring diagram or the white wire. 2) I converted the 10 hp briggs to an electronic ignition (yeah no more points!!!)and I have a black wire that comes out from behind the flywheel how does that connect to the tractor/ or switch/ or whatever (I use it to ground the motor to shut it off) {PS I tried a jumper between the white wire and the black wire and it did not shut off the motor} 3) Do the fuses have a direction in other words the fuse that has a long leg and a short leg attached to the metal box (~1" long) right now the fuses short leg attaches to the side closest to the switch and the long leg goes on the side that goes towards the regulator. Thanks for any and all help. JH
goatfarmer Posted October 6, 2004 Posted October 6, 2004 I'm interested in the shutoff question. I repowered my 3410 with a newer Briggs,with electronic ignition.I'm using an old starter button,with one side grounded,to shut down.
ReedS Posted October 6, 2004 Posted October 6, 2004 1)On my 3410's the white wire from the ignition switch connects to the points jumper wire at the points cover for eng shut down. You should have continuity to ground with key off if not make sure the switch grounds OK to the dash, I can't remember if there is a separate ground wire to the switch. You have a bad ign sw. 2)The black wire (unless you have a newr model with a flywheel alternator)should be connected to the ign coil and should go the points. 3)The circuit breakers may have markings on them as to which terminal is the load or batt(supply)usually on the bottom in the bakelite. I have seen them work in either direction although I personally prefer to set them up correctly. Of course without looking at the tracors this all from memory so this is just my 2c worth.
johnmonkey Posted October 6, 2004 Author Posted October 6, 2004 I removed the points and it is an older briggs with a starter generator. 1)So should I cap off the white wire? 2)I removed the ignition coil also so I don't have a place to terminate it at that place either. Thanks for the help so far. JH
ReedS Posted October 6, 2004 Posted October 6, 2004 I just looked at my 3410 white wire definately goes to points for shut down, if you have no continuity to ground key off on that wire ign is defective. If your not going to use it to shut the engine off I'd tuck it up out of the way and you could cap it or at least cover the end of it. I've never tried any of the electronic alternatives to points so I don't know to make them work with the standard wiring. As to the black wire; it terminates at a stud on the flywheel backing plate, under the shroud, so I'd probably just tape the loose up and/or tuck it into the points cover . How do you shut 'er off? Did you convert to batt power auto style external coil?
johnmonkey Posted October 7, 2004 Author Posted October 7, 2004 Thanks, I used the type of ignition where you have to repolarize the flywheel. Is that called a magnetron? There are no points or condenso and it does not have the external automobile style coil. JH
HubbardRA Posted October 7, 2004 Posted October 7, 2004 If the switch is from a tractor with a magneto ignition, it should have a terminal that shorts to ground when the key is off. You can test the terminals with a meter or a 12 volt bulb with two wires. If you use a bulb, go from the 12 volt terminal of the battery to the terminal on the switch, the bulb will burn if the terminal is grounded. If you use a meter, it will show 12 V. You can also set a meter for continuity, or resistance check and check between the terminal and the chassis. If you have no grounded terminal with the ignition off, then replace the switch.
johnmonkey Posted October 7, 2004 Author Posted October 7, 2004 Thanks, Rod. I will check which terminal on the switch and see which one goes to ground. BTW It is a brand new switch. What about the white wire?? Should I just cap it off? JH
HubbardRA Posted October 7, 2004 Posted October 7, 2004 John, Check to see if the switch itself is grounded. This could be the reason that the white wire does not go to ground when turned off, as said in one of the other posts. You may need to put a ground wire onto the switch in some way to make sure the case is grounded.
johnmonkey Posted October 7, 2004 Author Posted October 7, 2004 Well I checked the switch and the white wire went to ground. I then checked my jumper wire that I used. GUESS WHAT!- the jumper wire that I used yesterday had a short in it and did not bring the black wire to ground. I tried a new jump wire and PRESTO I was able to shut off the tractor from the key switch!! (yes I am happy!) I will hard wire it now and hook up my lights, amp meter, and a few other odds and ends and I should have me a rebuilt tractor. I rebuilt the BGB, new motor, rebuilt mower deck, repainted, repainted front rims with new front tires, all in all my nicest looking tractor. I bought it for $100.00 and have too much money in it (~700.00), BUT IT WAS FUN!!!. JH PS just don't tell the wife!!
Roy Posted October 7, 2004 Posted October 7, 2004 Johnmonkey, Can you post a picture of your tractor? Thanks,
johnmonkey Posted October 8, 2004 Author Posted October 8, 2004 I will try, I bought a $20.00 cheapy camera at wally world and have not had much luck with it. JH
