Welcome to my shop. Around here we have one standard: fix it right the first time, prove every diagnosis, and charge a fair price. These modules put real cart systems on your bench — motors, controllers, batteries — so you can tear them down, test them, and break them without eating a single part. Follow the course in order: start with the two free steps, Electrical & Safety Basics and the TXT48 simulator, then work your way down the path. The blue Up next button always shows where you are.
Follow each tech's course progress, certificates and simulator results in one place.
The day-one course for every new hire — free for any shop. How a circuit really works, powering 12V accessories from a 48V pack through a voltage reducer, fuses and relays, and a hands-on Meter School (volts, ohms, reversed leads, voltage drop) that sets you up for the simulators. Then three bench faults to find, safe lifting, and shop safety. Final quiz and a printable certificate for the employee file.
Run a virtual repair bay: a customer's E-Z-GO TXT48 rolls in with a hidden failure. Diagnose it with the meter and the Curtis 1311, fix only what's broken, and out-earn Pete on the leaderboard. 40 scenarios across 4 difficulty levels plus guided lessons.
The system where simple meets life-and-death: E-Z-GO's mechanical drum brakes, torn down to the bare backing plate and rebuilt with your own hands — springs, star adjuster, shoes, and THE castle nut that decides whether the hub spins its splines. Inspection calls, the stuck-drum trick, and a timed four-corner Brake Job Rally. Hydraulic brakes get their own lab soon.
Tear a SepEx drive motor down to the copper: armature, field windings, commutator, brushes. Bench-test mystery motors against real OEM specs, watch the Curtis controller's PWM drive the armature, and learn why a bad motor kills a $700 controller — before you condemn either one.
The second full shop-simulator game — Club Car's IQ platform and its invisible brain. The OBC that owns the charger AND the solenoid's ground, the MCOR pedal and its infamous "digital hiccup," six 8V batteries, roll-away braking push tests, and an IQDM handheld that keeps Current and History faults separate — including the ghost Throttle Fault 1 that fooled two shops.
The RXV generation and everything modern: three-phase induction motors with nothing to wear out, the squirrel-cage rotor, why the balance test beats any single reading, and how the Curtis inverter spins a magnetic field out of a DC pack. Watch a rotating field actually rotate.
The full shop-simulator game on the cart that humbles technicians: real RXV fault codes (25105–25108 and friends), the power-up self test, the electromagnetic motor brake trap, brake and throttle position sensors — and yes, the infamous spun hub. Specs referenced from manufacturer service literature; always verify against your cart's service manual.
Inside a 48V (51.2V) LiFePO4 pack: sixteen cells and the BMS bodyguard that disconnects them in a millisecond. Learn why lithium carts die without warning on hills, why packs refuse to charge below freezing on purpose, why the voltage curve makes your meter a liar — and why most "dead" lithium packs just need a tech who can read the app.
The gas side of the trade on the E-Z-GO Robin 295 twin: the no-start triangle (spark, fuel, compression — in that order), the kill circuit that murders spark for free, the pulse pump that runs on crankcase breath, and the showpiece — an animated CVT clutch you can watch think: flyweights, engagement, ratio, and backshift on the hill.
