Description

Details

Regulates and rectifies A.C. current to maintain battery/capacitor voltage. Perfect replacement for the expensive stock rectifier & Zener diode at a fraction of the cost.

Fits:

Norton Triumph and BSA bikes with single-phase permanent magnet alternator up to 215 watts.

Features:

Replacement for stock Lucas Diode-Rectifier
Rectifies and Regulates AC to 12v DC
Single Phase
Will work on both postive and negative ground systems
2 X 2 X 1/2"
Easy to follow wiring diagram
Made in U.S.A.

When combined with the MAP capacitor, is the absolute best combination for battery less operation. As a two piece assembly, the capacitor if blown will not take out the entire unit.

NOTE: For safety, it is best to use a battery for the brightest lights, especially at idle.
Wiring Diagram shown is for Positive (+) ground systems only. For negative ground swap the black (brown) and red wire positions

Easy installation instructions:

Attach yellow leads to the alternator.
The dark brown lead is positive. This lead gets connected to the blue/brown wire on the bike’s wiring harness. This blue/brown wire should go to the battery.
The red (or orange) wire is grounded.
Disconnect and remove the old Zener diode on the bike. Be sure to tape up the lead so it can’t short out anywhere.
We recommend you save the original parts.

Hello !!. I'm looking for a regulator for my motorcycle : Triumph 1966 TR-6. But the regulator that I need has 5 wire. ( an alteration for more brightness in the front light) .
If you have it, please tell me the price for it and how much total sending to Puerto Rico .( S&H) . I have a customer number with you : 46516 . Maybe expired but this is the number that you sended to me few years ago. Thanks for the information about this part.

Question by: Pedro Fontanez on May 9, 2019 3:44:00 PM

Pedro, I have a few questions: Was the battery charging prior to removing the rectifier?
If it was working at some point, it would then appear to be a 3-phase alternator. Without part numbers and photos of all your electrical components, I can only guess. A single phase stator has 6 inside poles and either 2 or 3 wires. A 3-phase stator has 9 internal poles and 3 wires.
1967 models came with a single phase stator or an ET(AC system) that used special coils. Does your bike use a battery? If it has the ET system, it will not.. It is possible your bike may have been changed at some point to 3-phase, but there is no way to tell withing you answering the above questions and sending photos of the components.
Please send your reply to rick@mapcycle.com

If indeed a 3-phase and you are not charging enough to keep up the battery it could be the rotor has been demagnetized enough that it is not putting put max current. To add more???’s over the years there were 2 3-phase units. One with 130 watts and one with 180 watts. Only way to tell is by part number

I recently purchased this item and I I have a question: The wiring diagram provided with this item shows it with a capacitor. I am using a battery so how do I wire it without the capacitor? Where would the black wire go? Do I have to have the capacitor?
ALSO If I wired it with a capacitor the diagram shows a wire from the capacitor "to the battery side of the switch".. Is this the ignition switch?

Question by: Terry HEIKKILA on Aug 8, 2019 7:35:00 PM

Having a capacitor wired in with the MAP4100 regulator/rectifier is an option for those who do not want to run a battery. The battery and/or capacitor are wired identically (positive to positive and negative to negative).
You can also have both a capacitor and battery in the same system, which is really handy if your find yourself with a dead battery. In that case the capacitor provides enough spark to start the engine.
When we instruct you to "run a wire to the battery side of the switch" we are typically referring to a key-type ignition switch, but it could also be a simple toggle switch on some custom bike.
Below is a link to our MAP4109 Battery Back Up Capacitor should you wish to install one:
