Helping my dad get his 1951 3100 back on the road. It had the alternator taken out of it and half of the wiring removed by a guy that used to work for us. He unfortunately passed away before he could rewire it. That was 3 years ago. Were having it towed to a great electrical shop so it can get back on the road. We have a full authentic harness for it that I ordered in 2015 from Jim Carter. WOW enough is enough!
1) I need the bracket that holds the generator to the block. I was told it was the same as the later 235 engine. This is a 216.5 I believe. Also, the generator we have is new, but 10 years old. It has an ear broken off. Can I buy this part? I can post pictures tomorrow.
2) I have this heavy duty signal stat turn signal. It had a cheap chrome one in it that didn't seem to work (could have easily been the wiring). I can not find a wiring diagram anywhere, and there is no model number on it. I belive it may be a 905? Id like to wire the button on the end for some cool period fog lights, and leave the high beam switch on the floor.
The wires are labeled as follows
Gray-115 Green-112 Gray W/ Black stripe-71 Yellow-111 Red-113 Black-116
The double white connector is labeled 31 and 33A. I think this is for the flasher. Any idea where I could purchase connectors for these? Can just cut the ends off, but would look nicer.
Thank You if you can help me, and will try and get more picture of the generator and the truck itself tonight. It was painted a long time ago, but is otherwise very stock! 216 with a 4speed. Learned to drive a stick shift in this truck 15 years ago!

Here is the picture of the missing mount and wires on the HD swich. The harness I bought is "with turn signals", does that mean it has wires to hook this up to? Really appreciate any thoughts here .

Thismay help. Use the wire colors. The numbers in Fig D are standard numbers used on a relay that you may need to buy. The harness you have is configured for turn signals in general. Depending on what bulbs and lights you are using. I don't think the harness will have the mating connector for the 905. That company I linked should have info on that.
Don't see any broken ear to comment on. You used the word alternator and generator. I do not know if you are asking if you can buy another generator or the part of the generator with a broken ear, but the answer is yes.
Thanks for the diagram, I did find that but it seemed the colors were off. But I looked at it again and it seems to be close. Printed it to give the electrical guy.
This truck had an alternator installed, with alternator brackets. They were removed. I saw those on ebay, but was hoping to buy a set with the missing bolts. Need the three block bolts, as well as the bolts on the generator itself. I attached the picture of a generator and circled the part that broke off. I am pretty sure its a common GM long style generator. They one I have was rebuilt and broke in shipping like 7 years ago. Would be nice to use it and just get a used backing plate I could swap on.
The wiring harness definitely does not have these connectors. I am pretty sure its from a volvo semi truck or something along those lines. Will probably just make new connectors.
Do you know a good place to call for used parts?
Thank You

1. Bolts are at the hardware store. Nothing special about old truck bolts. Bypassing brackets because they have no bolts is a mistake. 2. If the end plate on the generator is not pot metal, take it off and weld ear/search ebay for a parts gen/place a wanted ad here in our classifieds for gen parts and brackets. I'll bet someone has an end plate. 3. Why no pics of your generator. So we can see if it's fixable. 4. There will be several years of gens that can be donors. You show a gen with a commutator band. That is up to about 1953. I am guessing that the end plate is the same for long and short. 5. I assume you have decided not to go with an alternator and that you have a voltage regulator and you are in the 6V club.
No its 12 volts, but yes we are installing a regulator. Truck has not moved in 4 years, and when it did run. maybe 1000 miles a year. We also have a 1959 235 with a generator. Kinda like it stock. I do like the powermaster alternators that look like a generator, but literally have no accessories besides a radio. I ask for bolts as hardware store bolts definitely do not look like bolts from 1951. Plus I figure people have parts trucks. If I had pulled the alt I would have stuck the bolts back in the holes! Oh well. The truck and generator are at my dads house, have not been able to get over there. I am also fairly certain that the back is cast aluminum.
I really enjoy learning about these things, so I appreciate any comment. I know most of you know way more then I do. I mostly mess with Jeeps and have a 1967 Gladiator and a 1977 Cherokee, but just love old iron!
I will place a wanted ad when I have some good pictures!
Facebook just reminded me of this picture from 9 years ago! There is the 1951 and the 1959 soon after it was painted to a factory turquoise color! Also a picture of my dads 1969 Ford f250 next to my 1967 Gladiator. Cool stuff!

Hi! So I finally got back on this thing. Its hard because I am working and working on 3 vehicles basically at the same time. Seems like one set back sets me way back because ill jump to something else. Also cleaning our barn at teh same time and finding a ton of lost tools!
Here is the Generator. I believe the tag says M100304 7D2. I believe it is off of a 1957 truck built in April. This will work for this truck all the same right? Were all the 1951 216 trucks 6 volt from the factory? This truck has been 12 volt since before I was born. But our 1st series 1955 3600 project is all original 6 volt. Anyways, I could use a backing plate and the mount and hardware. If anyone knows someone I can contact on here with a stash that would be helpful. I took the generator apart and it seems unused. I looked on ebay I did not see any generator end plates ( end frame) that looked like this. This will these fit the 1951?
Thank You!

Oh my o my I'm lost, the older Delco generators are cast steel on both ends. I have one here that was off a 1956 235 but it has a broken ear on the end side. I hope I'm not giving bad advice here but if you can find a pre- 1958 12 volt generator from any GM product it should work. I believe the best one to contact is Justhorsenaroud. He seems to know a lot more than I do, and I don't want to steer you the wrong way with my RUBE GOLDBERG ideas. I do know that the 6 volt and 12 volt end plates work. Doc
Currently making 1954 3100 better than new and Genetics
With regards to the generator end plate/bracket. I guarantee there is an old time starter/generator shop within a reasonable distance from you. They will have what you need plus they can make sure everything is operating properly.🛠and no I don’t know more than Doc.Hall.

Is the generator the same diameter end to end, or does it step down smaller near the brushes? Either way, that alloy end frame can be welded by someone who is good with a TIG machine. It's a bit tricky to weld, but I've seen it done several times. There's also a non-welding repair method, so don't discard the pieces. I might have the right end frame stashed away amongst the piles of parts in my storage shed. Drop me a PM and let's talk! Jerry

The wiring of the turn signal belongs here in electrical.
The broken ear on a generator does not.
This is a lot of posts over a minor issue. Owners of old trucks need to learn how to search and find parts. The correct part for the broken thing they have in THEIR hands. We can help wire and advise welding but searching for parts is up to the owner, It's the basics of owning an old truck. We have advised to use wanted section. He has not. Now folks are offering parts. Read the rules. Out of control post.
