I have seen several post about installing a pore boy altenator that said to install in line a regulator so you dont get battery feed back when the engine is not running. If that is correct, what kind and where would I get what I need?

 

[newday777]

If you are asking about a voltage regulator, the car alternator already has one built in them. Is that the type of regulator you are asking about?

The only thing that might be inline with the battery is a fuse... some do some dont.

Like newday777 says, the external alternator has it's own regulator, the onboard regulator should be totally disconnected

Ditto, just rip out the OEM rectifier, the alternator has one in it already.

Incidentally the bikes Stator and rectifier are not only anemic, but totally unreliable, the alternator conversion gives you twice the power without any problems.

I certainly have to agree with that. My regulator/rectifier got so hot it actually set the bike on fire.

What about the thousands of Goldwings just like yours that have never had a problem with the regulator/rectifier? :?

Possible use of a 'Blocking Diode' on the BCL so the battery cannot return power through the alternator, but there is a diode pack inside to prevent that. Unless it's a safety that the designer want you to put in place.

The easiest way would be to use a relay if you were worried about the alternator shorting out. Otherwise just use a fuse at least a rating of 10 amps higher than the alternator output, this way if the rectifier bridge goes bad or a wire shorts to ground the fuse protects your wire from fire.

The diode sounds like it would be great, now what kind and where do I get one?

That would have to be one antique alternator that required an out board regulator. Buy something made in this century and you don't need anything else.

My 64 Chevy truck had an external regulator, what a PIA it was too! So much better with the built in regulators and electronics!

Are you sure that wasn't a generator you had?:ROFL:

KEN...!!! how could you...!!!!:lash:

In my first question I used the wrong word, (regulator) I should have said, relay? when wired up it has a one wire to the battery, voltage goes both ways. when not running, 12 volts go back into the alternator which will burn up something. I think I need something that will break current flow back to the alt. when not running.

It's the job of the regulator/rectifier inside your new alternator to prevent reverse current.

A fuse is good but many installations forgo this.

Bottom line is that you're over thinking this.

My 49 Dodge 1 ton had a generator.

You may be right, maby what I need to do is volt check my car on the battery feed wire as it is not running.

All that will tell you is that it is wired properly if you read battery voltage at the generator output lead. If the battery is being discharged when it is not running by current back flowing through the alternator then you need to fix the alternator and not treat the symptom by putting a relay in the circuit.
