I purchased this carbon fibre composite sheet on eBay so I can make a new switch panel for the new toggle switches.
It is 2mm thick and is made up of a carbon layer on fibreglass to keep costs down and provide the desired cosmetic appearance.

As part of my quest to add a few MK1 styling touches with my own little twist I decided I would replace the standard square rocker switches with the something a little more retro. The MK1's had a lever toggle switches with a ignition key in the centre of the switch panel. I will need to retain the standard ignition mainly for the steering lock which is an MOT requirement however, I am going to add a start button in the centre of the switch panel which is required as part of the Yamaha R1 loom. The standard rocker switches come in various configurations to suit the circuit they are switching. Although a range of toggle switches are available as direct replacements I realised I could use standard off:on toggles if I modified the circuits a little. I have spent a lot of time redesigning all of the circuits in Microsoft Visio to encompass the new toggle switches. I will post the schematics separately.
I have spent a lot of time recently studying the Rover wiring diagrams so that I can understand how each system works within the car and ultimately so that I can reuse as much of the existing wiring where possible. This wiring schematic has been designed to power the electric reverse motor that I will be fitting, a modified starter motor. I wanted to include a few safety features to prevent the motor being operated whilst the car is in gear and/or whilst the handbrake is applied. This circuit is based on an additional Auxiliary battery being installed and I will be running a split charge system. A small motorbike battery will be connected to the Yamaha R1 engine loom to power the ECU, clocks and starter logic and a larger auxiliary battery will power all the car functions.
The New Auxiliary Relay in the schematic will be energised by the bike loom once the ignition is in Position 1 but the power will come via the Auxiliary battery. In order to reverse the car, the following conditions must be met; 1. Must be in neutral to energise the Reverse Relay 2. Handbrake must be off 3. Dash mounted toggle switch must be on - This will illuminate a warning LED and turn the reverse lights on 4. A floor mounted push switch is pressed sending power to the Reverse motor The freezing tempatures have limited the amount of time I have been spending in the garage but I have managed to make a good start on sorting the wiring loom out. It might look like a big mess but its actually fairly easy to work with the loom once all the wrap is removed.
Working with the official Rover wiring circuit diagrams I was able to identify all of the injection specific wires and strip them out. I have updated copies of the diagrams to show what I have removed in case I need to add back in at a later date. |
