Video Summary: CF Moto 500 – Dead Dash, No Start, but Reverse Lights Work "If you have a CF Moto 500 with a good battery, and your engine won't crank and the instrument cluster is completely dead, but the reverse lights come on when you shift gears, you are facing a classic *electrical power distribution issue* specific to the main ignition-switched circuits. The key diagnostic clue here is that the *reverse lights work**. This confirms that power is successfully leaving the battery (which, when fully charged, should register **12.8V**) and that your main ground is functioning enough to power at least one circuit. This isolates the failure to the power path *after the battery, but before the main electrical systems—specifically, the systems controlled by the ignition key. Here are the *three primary suspects* causing this simultaneous failure of the dashboard and the starting circuit: #### 1. Main Fuse or Relay Failure Although you checked the general fuses, the problem often lies with a high-amperage fuse or a critical relay dedicated to powering all switched systems: *Main Fuse:* The vehicle uses a *20A main fuse**, along with auxiliary fuses of 10A and $15A \times 3$. This main fuse is typically located near the **Starter Solenoid* (Starting Relay). A fault here cuts power to the entire system before it reaches the dash or starter components. *Main Ignition Relay:* The CF Moto 500 utilizes a *Starting Relay* and an **Auxiliary Relay, Starting**. If the main relay (Ignition Relay) that controls the switched power fails, the dashboard and starter circuit, which rely on the switched 12V supply, will receive no power. #### 2. Ignition Switch Internal Failure The *ignition key switch* is the main distribution point. The switch may be working just enough to energize the secondary accessory circuit (like the reverse lights), but it has failed internally on the primary *run* or *ignition* wire—often identified as a *Red/White* or *Red/Black* wire leaving the switch. This stops power from reaching the main fuse box and the starter relay signal. #### 3. Corroded Ground Connection While the reverse light works, the starter motor and dashboard require a robust ground. You must check the main *battery ground cable connections* to the frame and the engine to ensure they are clean and tight, as corrosion can prevent the high electrical current flow necessary for cranking the engine. #### *Immediate Troubleshooting Steps* To resolve the issue, focus your checks on the following points: 1. *Locate the Starter Solenoid:* Inspect the large *main high-amperage fuse* located immediately adjacent to the starter solenoid. 2. *Test the Main Relay:* Find the main ignition relay and test for power flowing both into and out of the relay when the key is turned to the 'ON' position. Swapping it with an identical, non-critical relay can be a quick diagnostic check. 3. *Check Ignition Switch Output:* Use a multimeter at the back of the key switch to ensure the crucial *switched 12V* power is successfully leaving the switch when the key is turned on. By tracing the main power path through the main fuse, the main relay, and the ignition switch, you will pinpoint where the switched 12V supply is being interrupted."
