Alternator on RB 383
« on: January 31, 2015, 01:31:05 PM »

Ok, I am trying to convert my '59 to an alternator. I bought the adapter brackets, but the alternator is hitting the distributor. (The distributor cap is off for the picture, just to align the alternator, but it will not go back on..) Picture is below. Any advise??

I dunno rob.  Looks like you got sold a bag of goods.

Just a word of warning, you'll have to put a regulator on the gauges now.  Your temp and Gas gauge will pin

Definitely need the RB brackets. A wiring diagram that matches the alternator would be a good idea, too, make sure things are wired properly after the fact.

Thanks for the input. Do you happen to know where I would get the RB brackets? All I have been able to find are BB brackets...

Would the 440 brackets work? It looks like it takes the mount out a little more...I may try a thinner alternator as well though.

If i recall correctly, your 383 is an RB.  If so, the 440 Brackets are the right ones.  Then you can install a traditional Mopar Alternator.  Wiring is really simple.

Ditto. If there are three wires (a second field wire), the last one whatever color it is goes to the positive side of the coil. They are usually on the Lean Burn systems and it is used to power all the sensors and ties into the coil. Without it, it won't charge (ask me how I know).

Ed  I need to correct you.  The 12V for the charging system comes from before the ballast resistor.  The voltage going to the regulator is what it reads.  You can't go to the coil because that is 9 volts

Figured out part of the problem! (Hopefully! LOL) Pictured below is the new water pump housing that I had to buy. the hole that I am pointing at is where the top of the bracket is supposed to go...the same hole that my current water pump doesn't have. So now the alternator will be moved down by at least an inch, and moved outwards. Hopefully this works. Picked up a new water pump at the same time as I have been having some overheating issues.

We are both right. Had this problem on a 84(?) Ramcharger. The second field wire attaches, too, not instead of. With the wiring diagram for the two field wire alternator, it powered all the sensors (about five of them) and to the positive side of the coil. Once all the sensors were deleted, that wire had to go to the coil to keep charging. It was weird, but wouldn't charge otherwise.  Not to worry, it took em about an hour to trace the connection with the wiring diagram.

Have you done the radiator yet?
Ed.  Did the 84 have a dry coil?

Stock little coil bolted to the manifold. I think there were only two or three years they used the double field wire alternators. It is in the wiring diagram and like I said, took me a while to whittle out the wiring with all the sensors and narrow it down to the second field wire going to the coil.

No I was asking if the 84 had a dry coil or a wet one.

As she sits right now. Need to pick up a new drain plug for the radiator on the way home, but I think it's looking good.
