wireing a state rectifier

Post  jed on Mon Feb 07, 2011 1:21 pm

hi. is thare any one that can give me a diagramed for wire ring soled state rectifier to a falcon
the colouers are light green // white //and brown and translucent +earth
the old rectifier is earth to the frame.
thanks jed

I have just bought one of these and it came with some sort of instructions.

Terminal marked AC to alternator either wire.
Terminal diagonally opposite to alternator either wire.
Terminal marked + to positive.
Terminal diagonally opposite to - NEG

I am pretty sure if you have 3 alternator wires you join 2 of them tog and put the last one on alone.
Depending on your earth system you have to ground either the Pos or Neg terminal.
Just a link wire to the middle fixing bolt of the rectifier.

Hi
You need to be careful here if you are just replacing like for like for the rectifier you need to connect the new one exactly as the old one was connected.
AC terminal either one whitefrom altenator. Other AC terminal Light green 2 wires one from altenator and one to ign switch.
DC output Negative Brown to light switch ammeter etc.
DC + to earth ie frame.
If you connect the 2 wires from the altenator together you will be up to 12 volts and blow most of the bulbs.

The terminal with 2 wires on are not both alternator wires one goes up to the switches on the Falcon 87.
Light Green wires.

I stand corrected on that

wiring rectifier

Post  mike Sayer on Tue Feb 08, 2011 7:44 pm

Jed, I have a bridge rectifier KBPC35-01 with a diagram for the wiring but I`ve no idea how to put a picture of the diagram on the forum. I could send you a pic. with an email however if that`s any help.
regards, Mike. Very Happy

Replacing the Rectifier

Post  StuFalcon67 on Mon Feb 14, 2011 10:58 pm

I replaced mine with a number of silicon diodes - more than enough to carry the maximum generated current. But, I deliberately wired it as a half wave rectifier. I figured that the original selenium rectifier also acted as a sort of regulator so that the battery is not over charged. The other reason was that I could get the replacement diodes in the old flat rectifier can under the seat to maintain the look of the original bike. The electrics work fine the battery does not over charge but remains sufficiently charged as in line with the original specification. As such the bike would be run on AC for the main headlight and the battery discharges slightly with all lights on DC at the headlight switch. At dusk I use the park lights [DC] and the generator exactly matches the load at 20mph and above.
I considered that a modern bike bridge rectifier giving full wave rectification would over charge the battery. It took me some time to get my head around this - AC or DC lights!

Is not the resistor wire meant to stop overcharging?

On my 87 loom Im adding a modern rectifier, but also have kept the resistor in the same place, albeit a modern resistor and not the wire, to perform it's origional function.

It may well do on other bikes, but there was no resistor on my old wiring loom or on the cct diagram for the Falcon 67.

Ah, got you Stu, in fact I'll need to take what youve said into account for my next loom, for a Villiers 10e powered Falcon, that wont have a resistor built in then

I am still searching for the engine connector for the 9E where the alternator wires connect to the engine Loom end needed. if anyone had an old loom

Thanks

hi. Terminal marked AC to alternator either wire.green in then to loom then to ignition switch
Terminal diagonally opposite to alternator either wire.white
Terminal marked + to positive.translucence then to earth
Terminal diagonally opposite to - NEG brown to battery.. orangs to loom then to ignition switch
i all so put a + resisrance wire in thats goes to light switch
