No instructions with my 12V conversion kit

[Fiveflat]

I bought a 12V conversion kit for my '49 8N. It didn't include instructions. Doesn't anyone have a set in PDF format that I can download???

hey come with instructions? I did two and neither had instructions.

here's the wiring diagram:

any other questions, just ask.

Thank you, I suppose the wiring isn't too much of an issue but what I can't figure out is how to mount this alternator. The brackets just don't lineup to anything

 

[HFJ]

that's a fairly common issue. can post some pics?

This site makes it difficult to post pics... Finally got it done I think. The kit I got came with all the brackets in the first photo. I'm thinking I got the wrong brackets.

HFJ,

I'm anxiously waiting for enlightenment on this, as well.

'Sally', my new/old 1940 9N (13030) came with a 12 V/Neg conversion and her alternator pivot bolts (2) are connected with two short, previously hand made, side plates --- [u:b2d8cb3ddc]with[/u:b2d8cb3ddc] 1/2 " of washers top and bottom just to get 'sort-a' aligned. :~( She starts and runs well, but I'd MUCH rather know what the proper wiring and mounts should be.

Anyone have a clue on "Sally's Dilemma"?

Your "'48 8N" is either newer than that or has a newer engine, which means the generator is mounted on the left side of the engine, rather than the right side as it would be on an older engine.

Here's what you need for your newer engine:

That's the bracket I figured I needed, but I thought the water hose would be in the way. Thanks for the photo!

so I need that other sorta z shaped bracket as well then?

 

[wore out]

P.S....

The change of moving the generator was to accommodate the change from a front-mount to a "side-mount" distributor and was made at serial # 263,844, in mid 1950, so your engine is a at least a mid-1950 model, or a '51 or '52.

Is the serial number present, and did you cheek it before ordering a kit for a 1948?

Your guess is probably much better than mine. I interpreted this as a 17xxxx

 

[Fiveflat]

1949 started with 141xxx

ya, you've got the brackets for a front mount distributor block, but u have a side mount block. those brackets do a nice job of holding the alternator on the right side of the block.

another thing to check - did the kit come with a 5/8" alt pulley and belt? the standard 1/2" won't match the other pulleys.

I see: [b:7d33d8e117][size=18:7d33d8e117][color=brown:7d33d8e117]?[/color:7d33d8e117]N17232[/size:7d33d8e117][/b:7d33d8e117]

Since that is between Serial Numbers 1 and 37907 that should make that serial number (if I see it correctly) about the middle of the 1947 production run. (17K along a 37K year's production run.)

Other thoughts?

i see two competing landmarks - the serial number and the side mount dist. to me, the serial number is suspect. the first number appears to have been struck twice, and is that the ghost of a 3 underneath?

bottom line, the block clearly expects the gen/alt on the left, and these particular brackets are for the older block design, as mentioned by wore out.

(quoted from post at 20:45:23 12/13/20) I see: [b:52bf33896a][size=18:52bf33896a][color=brown:52bf33896a]?[/color:52bf33896a]N17232[/size:52bf33896a][/b:52bf33896a]

forgot to mention - i think i see one more digit:

8Nx72328 ?

 

[HFJ]

the more i think about it, the more i suspect the first digit is a 4. seems to me a capital I was used for 1.

 

[wore out]

Looks to me like 472,328 or close to that.

According to one source,1952 serial numbers run 8N442035 up to and including, 8N524076.

The more I look at it, the more I believe is probably is a 4...

boy, I really cuffuffled that one. Thanks for your help guys! I better look at that belt also then before I order the correct brackets...

The serial number looks like 8N472380.

YEAH, see WIRING PICTOGRAMS by JMOR. A '49 would have the front mount distributor. Pictures shown are a side mount. Front mount uses the OEM Ballast Resistor on a 12V switch over job. 12V battery, 12V alternator (1 wire best), alternator belt tension device, correct fan belt, Ammeter (or Voltmeter), Ignition Switch, external 1-OHM ceramic resistor if using a 6V Coil or eliminate this resistor replacing with a 12V coil, and new wiring. You eliminate the 6V 3-Wire Generator AND the 3-Wire Voltage Regulator doing a 12V job.
