Carabela wiring: 

Cateye Turn Signals: Cateye turn signal kits, made in Japan, were an add-on accessory. They had a rechargeable 5.5 volt Ni-Cad battery pack, mounted with the front two lights on a chrome bar that clamped onto a moped handlebar. All of those original batteries died in the early 1990’s.

CDI Wiring: 

Cimatti Wiring: Cimatti, with the Minarelli V1 engine,  has functionally the same as the “Minarelli Wiring”, except for the high-low beam headlight, the console light/horn switch, and the secret toggle switch under the headlight that grounds the blue wire when in the forward position.

Concord (Fantic) Wiring: Concord mopeds with Minarelli V1 engines have “Minarelli Wiring”. The ignition source ground powers the brake light and must be grounded to run. There is a secret resistor inside the tail light. When that burns out the engine dies when the brakes are applied.

Colombia Wiring: American-made Colombia mopeds can have two different frames, mono-tube and stamped sheet, and two different engines, Sachs 505 or Solo belt drive. But they all have the same Bosch 5-wire 90mm magneto, same wiring and electrical equipment, except for the headlight. Blue is ignition, green and green/black are brake light, yellow is head light, and grey is tail light.

Invisible Forces: Notice that on the Colombia (and others) the tail light gray wire goes straight from the generator/magneto to the light, and not through the light switch. You would think the tail light would then stay on all the time. The small tail light generating coil is close to the larger head light generating coil. Somehow the magnetic field changes around the head light coil when the light is switched on, and that energizes the nearby tail light coil. So the tail light only works when the head light is working. This prevents tail light burn out caused by overload from a burned out headlight. On other 70’s mopeds, when their head light burns out, the tail light gets super bright, and dies.

Furthermore on mopeds with a Bosch 90mm magneto with grey tail light wire, such as Puch, Batavus, Colombia, the headlight bulb is preferably a 6 volt 21 watt (#1129). If it’s a 12 volt 21 watt (#1156), the headlight won’t be as bright, and since it passes less current, the tail light won’t be as bright either. That’s weird. Besides that the tail light bulb needs to be a 6 volt 5 watt #63, or else it will be dim, especially at idle.

Batavus Wiring (early): The 1976-78 models with Laura M48 engine have a 90mm Bosch 5-wire magneto on the right. Those have an internal ignition ground. None of the lights matter for the ignition to have spark. Head light (yellow), tail light (grey), and brake light (green) each have their own generator coils.

Batavus Wiring (late): The 1978-80 models with Laura M56 engine have a 80mm Bosch 3-wire magneto on the left side. Those have an external ignition ground. That blue/black wire powers the brake light. Consequently there is a special brake light resistor inside the light. While the early ULO 2-bulb tail light did not have a facility for holding a resistor, the later ULO 2-bulb tail light did. In fact there was not just a resistor, but a small circuit board with a nichrome-wire-coil resistor, and a diode. Otherwise the ignition looses spark if the blue/black becomes disconnected.

Battery Wires: For vintage Taiwan-made mopeds with 6 volt batteries, General, Lazer, Angel, Speed Bird, Indian, AMS, Clinton, Grycner, and others, getting the correct battery, 6N2-2A or 6N4B-2A is easier than getting the correct battery wires. In the 1980’s, new replacement batteries had vintage moped wires (double female bullet and male blade or bullet, male bullet). In the 1990’s and 2000’s the replacement battery wires changed, see illustration. In the 2010’s the wires changed again to “universal” (female bullet, female bullet plus an assortment of plug-in adapter wires, all bullet connectors). But the assortment does not contain enough to make vintage moped battery wires. To make those from the assortment, cutting, soldering, and shrink-wrapping is required.

Some vintage mopeds have had the bike’s wires adapted to accept a modern battery. Because of so many possible wires, since the 1990’s Myrons has always transferred the old battery wires onto the new battery, whenever the old wires were available. When unavailable, adapter wires were made, mostly from wire scraps. So many have been made, that almost no traces of the old style battery wires survive at Myrons Mopeds, out of hundreds of moped wire scraps.

Benelli Wiring: The Benelli G2 moped has a Dansi 3-wire 80mm magneto, with an external ignition ground on the green wire, ignition on the red wire, and lights on the black wire. The Benelli Dynamo mini motorcycle also has a Dansi magneto. More on Benelli soon …

Bianchi Wiring: Bianchi mopeds, US models with Morini MO1 engines, all have Dansi magneto type 101732. This magneto is essentially the same as the 101765 3-wire 2-coil, with external ignition ground on the green wire. Ground the green wire to get spark before suspecting anything else. 

AMF Wiring: This wiring info is for the AMF Roadmaster models 110, 115, 120, 125 with McCullough rear friction drive engine, not the models 140, 141 with Minarelli V1 mid-engine and chain drive.

AMS Wiring: AMS Sierra 50 (step thru), Tahoe G1 (top tank) and Tahoe G2 (top tank 2 speed manual) have the same wiring as General 5 Star ST, except with a Taigene magneto, 3-wire with external ignition ground blue/black for battery charging, no ignition switch in the fork lock, and possibly minor differences in some connectors and grounds. Always ground the blue/black if there is no spark.  

The Taigene FP43 90mm 3-wire magneto is Bosch-compatible. Too bad it was prone to loose spark, even with the blue/black wire grounded and the points functioning. Some needed upgraded to an actual Bosch magneto.  

AMS & Angel Battery Versions: Angel/Speed Birds use a 6N2-2A small 6 volt battery, AMS uses a 6N4B-2A. Modern replacement batteries have different wires than the original ones did. See section “B” Battery Wires.

Angel: 1970’s Angel and Speed Bird mopeds, made in Taiwan by TYM, can have three different magnetos and two different wirings. These all have Ø90-three-M4-screw stator plates, and Ø90 (90mm ID) flywheel-rotors.

1) Bosch 0212-112-053, with brown (external ignition ground), yellow, black wires. The brown wire is the “tail” of the ignition source coil, and must always go to ground to have spark. It helps to power the headlight. So the headlight or headlight wires can cause the ignition to loose spark. 

2) Wtemco FHA ?????, with brown (external ignition ground), yellow, black wires. This whole magneto interchanges with Bosch 0212-112-053, but the internal coils are different. The flywheel, stator plate, points, condenser, the wire colors and wire plugs are all the same.

3) Wtemco FHA 11035, (internal ignition ground) with red, yellow, and black wires. This is the same as the other Wtemco magneto, except for the source coils (armatures). The headlight wiring is different from the others, in that the yellow does not get help from the ignition ground. This would make the headlight dimmer, but at the same time there is a separate output for battery charging, so the headlight gets brighter from that. The net effect is slightly dimmer.

Avanti Wiring: Early 2000’s Avanti mopeds have a 90mm 50W Seel magneto, made in India, with modern CDI electronic ignition. Mont and Autopower have 12VAC one-wire for all lights, with an electronic voltage (shunt) regulator. Kobra has 12VAC on 3 separate lighting wires, with no external regulator.

Avanti controls are copies of late 1980’s Italian made Domino controls, used on Trac, Tomos, Derbi. The switches are copies of late 1980’s Italian made CEV switches, that integrate (fit into) the mounts for the controls (brakes, start, and throttle). The switch buttons use the same white international icons, rather than words. 

The original switches for domestic (India) models did not have a handlebar mounted engine stop switch, reachable by the right thumb while holding handlebar grip. The older wiring diagram for Kobra shows this. Only the key on the dash would turn off the motor. But on at least the Supersport model, and maybe also on some Autopowers and Monts, they made the right side headlight high-low beam switch into a engine stop switch, in order to meet the US DOT requirement. This has been the source of confusion. (Turn on the high beam or it won’t start?)

These three wirings took 24 hours to interpret, colorize, re-draw and clean up. The originals were very rough.

Welcome to Myrons Wiring Diagrams. Mopeds have strange electrical wiring. Many have “secret” wires that must be grounded to run. Many have switches that normally would turn off something, but instead they turn on something (brake light or horn). Most of the wiring diagrams explain this, when it applies.

This “secret wire that must be grounded to run” system is only on most 1970’s and 1980’s US models. The reason for this craziness is that European mopeds do not need brake lights, but US ones do. So many kinds power the brake light from the back side of the ignition source coil.

One kind, Puch 77-later, 6-wire, powers the horn from the back side of the ignition source coil. So on a 77-on Puch, if you unplug the horn and push the horn button, the engine dies.

Besides loosing spark, older mopeds also often burn out light bulbs. That is because a magneto generator alone, without a battery or regulator, ranges from dim lights at idle, to bright at full speed. So your bulbs are either too dim, or else they burn out a lot.

Modern (1990-later) mopeds don’t have the old moped wiring problems. They run a more powerful magneto, 70-80 watts instead of 30-40. All the lights run off one wire, with a 12VAC voltage regulator. To keep the voltage below about 13V, the regulator passes any excess current into the frame where it’s mounted. So when most of the lights are off, the frame is being warmed a lttle. This “regulation by wasting” system is common on motorcycles but not automobiles.

Also nothing that the lights do ever matters to the ignition. Magneto ignitions after about 1993 are CDI (Capacitor Discharge Ignition) instead of points. They’re also maintainence free and have easier starting.
