Alrite here"s what you will need to whoop the 6v set up,,,, he he
Go to the local autozone advance or what ever chain parts store is in your area,,, ask for a alternator for a 75 chevy pick up C-10 350 engine. 10SI,,, you also need the pig tail for the plug in. If you can find a old alternator core to turn in it will save ya $15,,, Go to radio shack and git a pack of diodes # 276-1144
Go to Napa and git a IC14SB or IC64 coil
If your wiring harness is in good condition you can use it or git a replacement #8N14401C
I use interstate group 35 batteries,,, they fit the box and hold down used in a 6v application,,, enny battery you can fit in the box will work,,, TIGH IT DOWN
Store brought brackets are
8NL10303
8NL10302
8NL10304
ALT PULLEY # 98NAA5825
its the only pulley I would use period
You will need the bolts and washers to bolt the alt to the brackets,,, lower bolt is 3X8 X 4"
Top is either standard are metric you will need to check it,,, I always heli-coil adjuster hole even if it is a kit alt or make sure the alt you git has goods bolt threads,,, haft of"em you git are worn out.
Search for Bobs pix of the alternator and connector set up or Mail me for it or may-B he will ring in with it. I think you can use your belt,,, if you have a front mounted pump the loader pump shaft will have to come off.
Wiring harness modifications,,,, for the replacement 6V harness,,, I don"t use the 12V harness they are 2 expensive
Tie red & yellow at the regulator side of the harness together.
White wire izz the excite wire and goes to the excite wire at the alternator, tie in to the ignition switch or 2 post junction block on back of switch.
At the gen wire were they connect to the gen, use the bigger red wire as the Bat wire on the alt and the white wire as the excite wire. all the rest of the wires will lay in place as intended.
Bat wire at solenoid has the clear plastic (may have a black insulator wrap) on it were it hooks to the plus side of the amp gauge
other yellow goes to neg side of amp gauge
you will have one wire left over a black wire I think I like to use it fer headlights..
Cost
alt,,, $50 lifetime warranty try that with 6V
pulley $30
wiring $20
brackets $74
battery $60
mis hardware $5
Total $239.00
Kit price will B cheaper,,, I don"t like the kits so spend the X-tra 2 do it my way.
you have a modern system that will kick a 6vs arse,,, EZ parts availability with a warranty kin B found at most enny parts house/junk yard,,, EZ and cheap to repair,,, kin add on lights are what ever plow snow 24/7. A ignition coil that will out fire the 6 V coil,, EZ"er starting and cleaner burning,,, mite have a HP increase.
You will loose the originality aspect of a non werker,,, I here it said that 12v will mask problems,,, That"s proff its more efficient than 6V,,, will operate when 6Vs want... All the talk about grounds,,, NO system will operate efficient with a bad ground altho its possible for a sick 12V to keep up whereas a sick 6v will have ya lay"n in the snow.
Worst case install a 12V battery and a 12v coil,,,, disconnect the gen and regulator and your tractor will run for days on one charge,,, try that with 6vs.
BTW I have 2 tractor that have the dreaded 6V system,,, neither one have to werk for their keep. If they don"t start I will go git on one that will,,, I don"t have time to fiddlefart with"em. Worst case If I git caught off in a jam I can hook up jumpers and charge the battery enuff to operate the tractor,,, or look for a lone enuff power cord to charge a 6v battery or take the 6V bat out walk home and charge it. I don"t smoke but mite take it up,,, a 12V power outlet would come in handy
*note on the alt
ELECTRICALLY, a good choice is a Delco 10SI, from a 1975 to 1985 Chevy pickup, sometimes sold under a rebuilder"s industry standard # of 7127.
The alternator"s case can be CAREFULLY partially separated, and "re-clocked", it is a good idea to verify the alternator you purchase has the connector pointing in a way that will work for you, 12:00.
I have not tryed it but have seen were a 12V 10SI alt will fit rite in the generator clap"n band,,, If I did give that way a ago I would run a decated ground to the alt case from the battery.
