150-250cc Quad Wiring Harness – Full Loom with Stator, CDI, Coil and Rectifier

This 150-250cc quad wiring harness is a complete electrics kit for quad bikes and ATVs with 150cc, 200cc or 250cc push rod engines. Along with the main loom you get the stator, a twin-plug CDI, ignition coil, rectifier, solenoid, key switch with two keys, a handlebar switch cluster and a spark plug. Easy Life Markets sells it as one set under the supplier's model number 495148, for owners rewiring a quad from scratch or rescuing one with burnt, chewed or hacked-about wiring.

Anyone who has tried to trace a fault through a twenty-year-old quad loom knows why a full kit makes sense. Connectors corrode, previous owners splice in extra wires, and parts get swapped for ones that do not match. Starting again with a loom and components that were packed together removes most of the guesswork. The supplier states that the CDI in this kit is AC fired, which means it takes its power from the stator rather than from the battery. If that term is new to you, the article on capacitor discharge ignition explains the difference between AC and DC units.

What Is in the Kit

1 x quad wire harness (main loom)
1 x magneto/stator with two mounting holes
1 x twin plug CDI
1 x ignition coil
1 x spark plug
1 x rectifier
1 x solenoid
1 x key switch
2 x keys
1 x e-start / kill cluster switch with remote choke

The supplier's own line for the stator reads "2 x mounting holes Magneto/Stator", which we read as one stator that mounts on two holes. If you need that confirmed before ordering, ask us. A battery, flywheel, lights and instructions are not included.

The supplier asks buyers to allow a difference of 0.5 to 1 inch on any measurements because they are taken by hand, and notes that colours may look slightly different from the photos on different screens.

Will It Suit Your Quad?

The supplier lists this kit for 150cc, 200cc and 250cc push rod engines and names no makes or models. Quads in this class are built by many factories and the electrics vary, so please compare these points with your machine before you order:

Engine type. The kit is listed for push rod engines. If your engine has an overhead cam driven by a chain, check with us first.
Stator. Remove the flywheel cover and compare your stator with the photos: the number of coils, the two mounting holes and the plug on its lead.
CDI. This one is AC fired with two plugs. An AC CDI and a DC CDI are not interchangeable, and mixing them up is a common reason a rewired quad has no spark.
Connectors. Compare the plugs on your existing rectifier, solenoid and switches with those in the photos.
Loom length. Lay your old harness out and compare the reach to the handlebars, the engine and the rear of the frame.

Signs a Quad Needs Rewiring

No spark, or a spark that comes and goes when the loom is moved
A battery that will not charge even though the engine runs
The starter clicks but does not turn, or does nothing at all
The kill switch or key no longer stops the engine
Melted insulation, green corroded plugs or sections of household wire twisted in

Installation Notes

The supplier is clear on two points: no instructions are included, and professional installation is highly recommended. We agree. A full rewire is a satisfying job if you are comfortable with a multimeter and a wiring diagram, and a frustrating one if you are not.

Photograph the old loom, every plug and every earth point before you remove anything.
Find a wiring diagram for your engine type and keep it next to you.
Fit the stator first and route its lead away from the chain and the exhaust.
Lay the main loom along the frame and plug in one component at a time, testing as you go.
Earth the coil, rectifier and loom to clean bare metal. Poor earths cause most charging and spark faults.
Mount the rectifier where air can get to it. It runs warm.
Leave the battery disconnected until every plug is in place, then check for spark before fitting the bodywork.

Why Replace Everything at Once

On a quad the stator, CDI, coil and rectifier depend on each other. A stator from one source and a CDI from another may have different plugs or different triggering, and you end up chasing a fault that is really a mismatch. With a 150-250cc quad wiring harness kit, the main parts are supplied to work together, and the new key switch and switch cluster replace the two items that suffer most from weather.

Who This Kit Is For

Owners restoring a 150cc to 250cc quad or ATV, people who have bought a non-runner with missing electrics, and small workshops that repair these machines and want every part in one box.

Common Questions

Is the CDI AC or DC? AC fired, according to the supplier.

Are fitting instructions included? No. The supplier states that instructions are not included and recommends professional installation.

Which brands of quad does it suit? The supplier does not name any. It lists 150cc, 200cc and 250cc push rod engines only, so compare your stator, CDI and plugs with the photos.
