The operation of the switch is best checked when the red wire is connected, which is energized. In this book, you must first find suitable wiring diagram. Find on the diagram the place of supply of electric current and its distribution. Verification is carried out using current lines.
Using a test lamp with a needle contact, you can pierce the wire insulation and determine which wires conduct electricity.
First, it is checked whether the switch receives voltage at all. To do this, repeatedly turn on the ignition or lighting.
Then it is checked whether the switch passes on the voltage in the corresponding position.
For example, the following is prescribed for the glow starter switch:
red wire (terminal 30) must continuously conduct battery current.
gray wire (terminal P) is energized when the ignition switch is in neutral position: when the ignition key is turned, the wire is de-energized.
yellow-black wire (terminal X) is energized only when the key is in position "Ignition on".
The black wire of terminal 15 receives voltage when the key is in position "Movement" (1st step). "Pre-glow" (in release model until July 1977) And "Start".
Red/white live wire when key is in position "Pre-glow" (in release model until July 1977) receives voltage when the key is in position "Start".
Using the connection diagrams, other switches can also be checked accordingly.
