🔵 **NEW LESSON NOW LIVE – SIMPLIFYING WIRING DIAGRAMS**
A new real-world diagnostic lesson has just been added to the Skool. https://www.skool.com/rms-auto-electrics-diagnostics/classroom/35d6830f?md=e37ca921f0da4016b3c74e94315f375d This one starts with a **1994 VW T4 with completely dead wipers**. Rather than trying to follow the whole wiring diagram backwards and forwards, I show how I **strip the diagram down and redraw only the part of the circuit I actually need**. We then use that simplified circuit to decide **where to test next**, follow the evidence and eventually prove the fault. 💬 **QUICK QUESTION:** When you're faced with a big wiring diagram, what do you normally do? 🔹 Follow the original diagram as it is 🔹 Redraw/simplify the circuit 🔹 Print it out and mark your test points 🔹 Just start testing at the component 😬 **And be honest! 😂** Drop your answer below 👇 The lesson is live in the Skool now — have a watch and let me know if simplifying the circuit like this is something you'd like to see more of. 🥕 **JOB'S A CARROT — Follow the Process, Find the Fault**

Claims 3.3v-65v DC.
Questions time
I was asked why some front brakes have the caliper at the front of the disc and some at the rear?? Who will be first with the correct answer and have you ever thought about why???
