Distribution Terminal +X

Distribution Terminal +X:




Operation
The positive supply is taken from battery 1 to ignition switch 20, across distribution block 75 and 29-pole white connector 152A.

When the ignition switch is set to the parked, drive or start position, terminals 30 and X of the ignition switch will be interconnected. The +X supply will then be connected to fuses 20 and 23.

On certain markets, the +X supply is also used for the burglar alarm (connector 289) (1989 model).

2. Check the terminals of distribution block 75.
3. Check the terminals in 29-pole connector 152.
