എന്താണ് ഉൾപ്പെടുത്തിയിരിക്കുന്നത്

• MSD 8739 Two-Step Module Selector

സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

The MSD 8739 Two Step Module Selector requires connection to an existing MSD Soft Touch Rev Control or MSD Timing Computer. Professional installation is recommended.

വയറിംഗ് കണക്ഷനുകൾ:

Refer to the wiring diagram provided with your MSD Soft Touch Rev Control or Timing Computer for specific connection points. The 8739 unit typically connects to the module input terminals of the main ignition control unit.

• ശക്തി: Ensure the ignition system is off before making any connections.
• മൊഡ്യൂൾ തിരഞ്ഞെടുക്കൽ: The 8739 unit facilitates switching between two RPM modules (not included). Insert the desired RPM modules into the designated slots on the 8739 selector.
• സജീവമാക്കൽ സ്വിച്ച്: Connect an external switch (e.g., a clutch switch or transbrake switch) to the 8739 unit to activate the second RPM limit.

Note: RPM Modules are sold separately and are not included with the 8739 Two Step Module Selector.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The MSD 8739 Two Step Module Selector allows for two distinct RPM limits to be used. One RPM limit is active by default, and the second RPM limit is activated via an external switch.

Setting RPM Limits:

1. Install the desired RPM modules into the 8739 selector. For example, a lower RPM module for launch control and a higher RPM module for general engine protection.
2. Ensure the 8739 unit is correctly wired to your MSD ignition control and the activation switch.

Using the Two Step Function:

When the activation switch (e.g., clutch pedal depressed, transbrake engaged) is active, the 8739 unit will engage the RPM limit of the second module. Releasing the switch will revert to the RPM limit of the first module.

This functionality is commonly used for consistent launch RPMs in drag racing or other performance applications.

മെയിൻ്റനൻസ്

The MSD 8739 Two Step Module Selector is a solid-state electronic device and requires minimal maintenance.

• പരിശോധന: എല്ലാ വയറിംഗ് കണക്ഷനുകളിലും ഇറുകിയതാണോ എന്നും തേയ്മാനമോ നാശമോ ഉണ്ടോ എന്നും ഇടയ്ക്കിടെ പരിശോധിക്കുക.
• വൃത്തിയാക്കൽ: Keep the unit clean and free from excessive dirt, moisture, and extreme temperatures. Use a dry, soft cloth for cleaning.
• Module Care: Handle RPM modules carefully. Ensure they are seated correctly in the selector.

ട്രബിൾഷൂട്ടിംഗ്

If you experience issues with your MSD 8739 Two Step Module Selector, consider the following:

• No Second RPM Limit:
  • Check all wiring connections, especially the activation switch. Ensure the switch is functioning correctly.
  • Verify that the RPM modules are correctly inserted and are the correct type for your application.
  • Confirm that your MSD ignition control unit is compatible with the 8739 selector.
• Incorrect RPM Limit:
  • Ensure the correct RPM modules are installed for the desired limits.
  • Check for any loose connections that might cause intermittent signals.
• Unit Not Functioning:
  • Verify power supply to the MSD ignition control unit.
  • Inspect for any visible damage to the 8739 unit or its wiring.
