Use the wiring diagram in the manual

 

diodes on the hydro HANDLE are for the auto header height control - prevents current feed back - yes they have to be there - can you say Radio Shack.

As to the lights - the bin unloader and service lights all come off the secondary circuit breaker that feeds off the console relay.

 

i would be using my manual except i think someone was changing oil or working on a header or something because a couple of the wiring pages are smeared with dirt or oil-unfortunately the ones i need!

Thank you tbran. The one i'm talking about is mounted underneith the console, away from the lever itself, but mounted on a support bracket between the reverser swith and light switch cluster, next stupid question....i don't AHHC, or plan on getting it, do i still need the resistor?

 

I think I have those diodes. Get me a part number . you can have them.

 

It's possible that the resistors that you are referring to are the ones that provide the ground for the reversible motor on the variable speed reel when the machine is not equipped with variable speed header drive. With vari-header drive the motor grounds back through the coils on the hydraulic stack.

 

sorry, guys my bad, its the throttle level bracket that its mounted on. Had another look today. its connected between a yellow and yellow/grey wire out of the wiring harness for all the light switches. also visited a friend who had on old N manual and had a look at the diagram, still no idea what the heck it does. also doesn't show up in the parts catalogue as far as i can tell and there are no markings on it, or whats left of it i should say

 

its a resistor, Scott.

 

That looks like the 10 ohm 10 watt resistors we used when converting old combines and tractors from generators to Delco alternators. Is it 1/4" - 3/8" square and a bit over an inch long? They were a dollar or two at Radio Shack, years ago. Wire them into the circuit between the ignition switch and the #1 terminal on the alternator. That's the spade lug, not the power terminal. The resistor substitutes for the alternator light or resistor wire in factor installed alternators.

 

ya thats about the size of it. I'll have to go to the local electronic store and see about one as Radio Shack was bought out around here years ago. I can see in the manual i borrowed now that you mentioned it, mounted as you say between the ignition and altnernator. Any idea why it would be in the state that its in now? Would this indicate a larger problem? Forgive my ignorance, i'm not much of an electrician

 

It looks like mechanical damage to me. Did it lose a fight with a large hammer? An electrical fault should have smoked that thin wire before the ceramic housing blew up.

 

could have been for all i know. was like that when i opened it up. pervious owner did some rewiring i think on the reverser and he installed a cb too so i have no idea how it happened. still trying to get my work lights going tho....

 

can anyone else give me a little more info why this resistor is in the combine? i went to the local auto supply store and they couldn't find anything bigger than 1 ohm resistance, and seemed baffled why i would want one so big. Had to order one at the local agco dealer where he said it was installed when they switched from using 105 amp alternators to 110 amp ones....? He couldn't understand why its there either over a 5 amp difference. Anymore thoughts anyone?

 

yea, this was for the exciter wire , switched, to the DELCO alt. I thought they used 2 5 ohm in series 71321180 's - about $9@ ? just like quappelle sez and I think I have seen them a lot later than the N's....

 

I'll take a guess. The 110 volt alternator was designed with a warning light in the circuit and the 105 wasn't. I have no idea why they'd use a 1 ohm resistor with the 105, but it might be for static suppression or to set up a voltage differential between the regulator and the alternator output voltage.

 

Ordered one from agco, cost about 20$ on a stock order. Don't know how it got smashed but it'll be good as new next week. Being broken like it was, would that cause any adverse effects to my electrical system?

 

anyone know why some machines have the 105amp alternator and some have the 110? why did they switch? There appears to be a draw now in my electrical system somewhere, guage is reading between 11 and 12 whenever i run the combine and i get the battery beeper everytime i switch on a light or use an electro-hyd. suggestions anyone?
