Rectifier problem Falcon 58 (6E Engine)

Rectifier problem Falcon 58 (6E Engine)

Post  HyFy on Fri Nov 18, 2011 9:12 pm

Hi to all the helpful experts,

I have a Falcon 58 and on fitting a modern battery inside the original Exide casing I found it flat after a few days. I later found a constant drain of 20 or so milliamps with nothing switched on. During the process of elimination, I disconnected the (well insulated from the frame) rectifier and the drain stopped. Is it worth performing any other tests on the rectifier or should I simply get a modern solid state one. If I get a new one, are there suggestions for hiding it? I will not be doing any Concours D's but maybe the odd event such as the Exeter Trial (on the doorstep). Will the scrutineers be looking for this sort of hidden "updating"?

What recommendations are there as to sources of a replacement. I see mention of Alan Osbourne and also VWP in previous threads.

This is a two terminal rectifier on a positive earth bike. Is there a consensus as to wiring in a modern rectifier.

In preparing for night trials is there any other advice? Am I being a bit unreasonable to expect the standard system to cope with long night distances. The original battery I note was 12 a-h. I can't recall having had any problems back in the 60's when I used to "socialise" during the dark hours with the set-up. The battery that I now have fitted inside the original casing is 6 a-h. Am I expecting too much or do I need to review it all.

In a previous thread, I saw the mention of LEDs to reduce battery drain. I take it that as this is a positive frame bike they are a "No-No".

Any views or suggestions will be gratefully received.

Any other advice towards my goal...

Rectifier

Post  kerabo on Sat Nov 19, 2011 8:27 pm

I would just fit a modern one. There is a marvelous little thing out now called an A reg 6

A REG SIX 32.95
This 6V regulator will suit any Lucas / Miller type 6V alternator and will give proper Voltage control to prevent boiled batteries/blown bulbs and allow the safe use of AGM batteries such as the Cyclons. Because of the way the alternator is wired more power is available if the battery is low.

They come with full instructions. Pt.no. AREG6

67 x 59 x 24MM mounting holes 6MM dia. 55MM apart

This is a solid state rectifier and reguualtor combined. I just bought one from paul Goff. Not very big but you can forget all those resistor wires and just let it take care. Mine is under the seat.

Thanks for that Ken

I had read your previous threads. If you have solved the problem then it is solved. I will go for it. I will await anyone telling me that a trial scrutineer might exclude me for not being "original". But I will deal with that accordingly. Tell me more about your source or should I know already?

Not entirely sure this will work with the flywheel generator on the 6E engine,best to check with the suppliers ,it will definately work with the lucas or wipac alternator/rotor system on the AMC engines though.JH

rectifier

As John said will it work.Maybe you should check. If you already have a rectifier then it should replace this one.

Here is the link to paul Goffs site. If you mail him he is very helpfull. but i think it will work.
i do know that these dont need a switch to disconnect when not running because i asked him.
