I got my ol' 41' runnin' now but I went and changed everything to 12 volt and I just don't think my old generator is keeping up. I wonder if anyone out there knows a good little alternator that will fit in there nicely and what it came off?

A Delco 10SI or 12SI seems to be the choice out there. Mainly because they are low cost, easy to work on,and parts are available for them.

There are some smaller alt. out there which come off of later model cars.
They're cute but coat more.

Why do you think your Gen. is not keeping up?

What is the condition of the system (generator, regulator, wiring/connections)?

If your truck is mostly original and does not have a lot of electric accessories, the Generator will work great.

When I got the newer motor from an ol guy that had just rebuilt it it didn't come with the generator, I had an old generator from an old truck I had before, and just put it on. It's funny because the truck will run just fine on a dead battery, but it doesn't seem to charge the battery as I go, it might be something with the regulator maybe, but it is brand new I'm just kind of stumpt a little bit. I think I might have to run by one of those generator shop and just have it checked by someone that is a little more certified than me electrical stuff is not my strong point. I just kind of thought an alternator might be a steadfast way to go. I don't have any other electrical accessory s it's just bare and stock as far as electrical stuff goes. But since I've switched over to 12volt I have to replace the heater motors over to 12 volt. That's about all I can say about that.

What does the delco come off of?

brother, you've got the right idea re getting the setup checked by a competent shop, and if you're having trouble figuring out the stock setup, an alternator won't be any easier - a Delco 10 or 12 is the standard GM alternator used on most things, from early to current, but your main problem [aside from how to hook it up] will be the mount and adjuster arm, they weren't on anything as early as the 235 .... if the shop can't get the generator setup going, they might have some advice for an alternator setup, and you might find some helpful info at Mad Electric

Have you tried"flashing" the regulator,which fields the generator to the correct polarity.

Yes http://www.madelectrical.com/electrical-tech.shtml has some great info on the alternator. The only discrepancy i have found is when he talks about the one wire system does not have the capability to have a tattle tell light to notify you that the alternator stop working. I found that ron francis does sell a thing that will make your one wire system tattle tell when there is a problem with the charging system like a broken belt.

You have the right idea have a professional check it out if your not sure. I would still change it out to the alternator but to each is their own.

can you link that item?

On my 12v-conversion one-wire alternator 54 truck, I can easily tell when the alternator is not charging. The original ammeter tells me.

There is no need for a "tattle tell" indicator light ("boob light"), unless you "modernize" you dash/gauges. If you have no ammeter/voltmeter, an alternator-working indicator light would be nice.

Does the 58 have the light or the guage?

brotherwarrior is talking about a 1941 truck, it's not likely he has or wants an idiot light, which didn't appear as a replacement for the ammeter until the 60's - as Tim points out, any vehicle with an ammeter [or volt meter] doesn't need a light

It helps if I read thru the whole thread, I was going by the title of the thread.

Whether you dealing with a 1958 truck (here's a 59) or you are dealing with a 1941 truck (here is a 42), if you have your original gauges, you have an ammeter.
