TACH FINDER & USEFUL TIPS
TACH FINDER MODE:
This Tach Finder mode can assist in locating a Tach source for your installation. When following the steps, the unit will
begin to flash the parking lights if you have the Red/White wire connected to a tach source. If lights do not flash, then try
another wire until you locate a tach signal that will cause the Parking lights to flash. NOTE: On some vehicles equipped
with daytime running lights, it may be difficult to see any flashing parking lights. In this case your only notification will be
the slight “ticking” sound coming from the module’s flashing light relay.
TACH FINDER STEPS:
1. Open hood (or ground Gray hood pin wire if no hood pin is installed)
2. Start Engine with the key. (Pink wire must be connected!)
3. Press the Program button for 2 seconds
4. Lights will begin flashing if the Red/White wire is connected to a valid tach source. If not try a different tach wire.
5. Once Tach is located then turn off engine and close hood to abort (Remove Gray wire from ground).
6. Now follow the Tach Programming steps.
TACH FINDER TIP: Cold Weather / High Idle Simulation:
The tach finder mode can also be used to help determine how your CoolStart system may operate in a cold weather
situation. Once you have a valid tach source programmed into your system, follow test steps below.
1. Go back into the tach finder mode.
2. You should have a consistent light flash (like directional or emergency flashers).
3. Slowly raise the RPM level on your vehicle to simulate a “warm-up idle” that is higher than the normal idle level. If and
when the lights STOP flashing. Means that this is the point at which the tach signal is out of range of the system.
4. We recommend that you bring the RPM level up to between 1000 and 1500 RPMs to simulate a cold morning idle.
5. If the lights stop flashing too quickly, then we recommend using another tach source. This may help prevent the engine
from starting and stalling in the morning or cold weather.
