Parallel Alterntors for faster charge.

[MattZ]

The forward conduction voltage of an SCR at rated current is about 1.8V. For this reason I would not recommend it for the application being discussed.

As i have no idea whats inside an ALT's, can some one please send me a schmatic of a typical alt system.

MATTS ...I think you lost the plot those are a tripple diode pack not SCR ...the only scr used was in the locked on VSR

DAVE J its called Google

Below is a block diagram of an alt internal workings:

A pretty good if basic description of their function in a vehicle context can be found here.

On the subject of SCRs, I've never seen one used in a charging application. The most common component used for parallelling batteries is a Duralit relay if you want cheap, or an Albright contactor if you want good and reliable.

that is the worst altenator diagram I have ever seen ...Its three phase for gods sake ..

Duralite relay ...take the top off ..examine then put it in the bin ....

Some newer model cars have five phase alternators.

[pistnbroke]

yes a 10 diode alternator and rotor current ECU controlled .....

Yes, as was explained in a simple to follow manner in the link that I supplied in the same post.

At least I was trying to help the poster rather than ridicule him.

Ooh, ooh, see - we CAN agree on something

Has anybody considered a boost converter for getting a full charge on the house batteries from the starting battery and charging system? It's kind of a DC transformer.

The RE55 which you can use on either of the two practical circuits allows you to boost the voltage by 1v ( 14.4 to 15.4) Unless you want to reduce the life of the batteries ....you will be charging them every 24 hrs .....it is not advised to go higher ....25 A is as much as you can push into every 100AH without damage..

Sterling supply a product that addresses the same issue.

There are lots of solutions out there.

In the FAQ about batteries I agree with every word and for that link WitEver I will upgrade your rep ..!!!

Don't get too carried away there fella

I happen to believe that this page gives a more balanced review of the situation by someone who doesn't want to sell you an alternator controller.

So maybe you should leave my rep where you believe it belongs
