What im planing on doing is change the plug on my harness to a newer plug and alt ... The CS130 as a example..... I will need to bypass the VR like that plug that comes in the kit in post 23... In Joes case if he honest have a VR to mess with..
I eventually want to stick the battery in the trunk and clean up the engine compartment area with the EFI and less wires simple and clean
There are one wire internals that do have an indicator light function. There are also regulators that attach to the alternator case of the external regulated alts, one of them making the alt a one wire and it has adjustable voltage which is something you may want to consider if you will be putting the battery in the trunk.
You don't need to buy and hide the plug to bypass the regulator. Just know what to do with the wires.
If OHC Joe wants to do a conversion and have the indicator light on, he will have to find the light wire. It goes to the external reg. Joe follow the wires from the alternator plug.They will lead you to the regulator.
There are a few ways to make a one wire alternator. Some do not have a light function and one does. This is refering to the SI series alts 10SI 12SI 15SI etc.
It needs to spin 1500-2000 + generating a magnetic field that excites the regulator and latches the relay in the regulator to the battery,
Well that is sort of right. A 3 wire alt uses the wire from the indicator light or resistor to excite the field(rotor). It's not the regulator that is excited. The one wire has no external connection to the regulator, so it is called self exciting. The cut in speed of a self exciting one wire can be less than the 1500-2000+ mentioned above depending on the amount of residual magnetism in the rotor and if the wire wound resistor on the regulator is eliminated. If there is no residual magnetism in the rotor it doesn't matter how fast it spins, it won't excite (activate). When the rotor spins, the tiny amount of magnetism left in the rotor poles (residiual magnetism), induces the stator winding to produce AC power to the rectifier and diode trio. The trio rectifies the AC to DC and is fed to the rotor to excite (activate) it. Once the rotor is excited the regulator controls the field strength to the rotor .
I sell quite a few of these, like for tractors and other equipment. Our 1 wire is definitely not self exciting.I even have instructions to make turn on, and what has to be purchased to make turn on.have the instructions at work. I give copies of them when I sell a 1 wire.I know it involves a relay.
All you have to do is put power to it when the key is on the start position.another way is to rev the engine, I beleave over4 grand
Stellar, do you have pictures of one of those old Pontiac alternators apart? Can you still get parts?
I didn’t realize it was that low of an rpm…. Good to know! Just saw your post…. I have a kit I made up so a person doesn’t have to remember to spin it that high to power it up. Most purchase the kit
I bet I sell one about every two weeks. Sometimes more. I live in a farming community ands there very popular with farmers
Plus they are a good forty bucks cheaper than the normal two wire. Ours have a port covered by a little rubber flap where you with a terminal where you can hook up a power wire.
Bob, I have or can get just about any part you need. What pictures would you like? An early externally regulated or an internally regulated?
Pictures of the internals of the 68 Pontiac internally regulated parts would interest me. I've had plenty of 10DN's and 10SI's apart, but have never seen one those older internal regulated ones.
