For owners of the early Type 14 coupé, accurate electrical schematics are non-negotiable when troubleshooting or restoring original wiring. Start by locating the factory-issued Fahrzeug-Elektrik Plan (part number 113-971-0xx),.
Install a CH Type Loadcenter with a main breaker rated for 225A to ensure compatibility with service conductors sized at 3/0 AWG copper or 250 kcmil aluminum. Connect neutral.
Always begin by cutting power at the circuit breaker. Verify voltage absence with a multimeter–probing both terminal screws and the grounding point ensures no residual current remains. Standard 120V.
Begin by identifying the primary alternator output terminal–typically marked with a bold “+” symbol or color-coded red. Secure it directly to the battery’s positive post using 16 AWG or.
Begin by identifying the main power input terminals on your device–typically marked with +12V, GND, and REM. Connect the +12V terminal directly to the battery’s positive terminal using 8-gauge.
Start by activating the Shapes panel in your document editor. Select Insert from the main menu, then choose Shapes to expand the dropdown gallery. Locate the Basic Shapes section–these.
Begin by locating the under-dash fuse box on the driver’s side–this serves as the primary hub for factory-installed auxiliary modules. Pinpoint the vacant relay slots or designated connector ports.
Start with a primary feeder line sized for peak demand plus 20% redundancy–calculations based on the Hazen-Williams formula ensure minimal head loss. Use Class 52 ductile iron for mains.
For critical automation setups, use a dual-channel input configuration with forced-guided contacts. This design ensures that even if one contact welds, the secondary path maintains isolation. Industrial standards IEC.
Start troubleshooting or modifications by locating the central fuse box under the dashboard–pinout labels match OEM documentation directly. Reference wire colors from manufacturer specs rather than third-party sources; inconsistencies.
