System OverviewSystem Overview

• TAS is an automatic start stop system• Keeps the engine in a ready to go state at all times• Reduces engine wear• Increases miles between oil changes• Provides auto control for recommended high idle RPM• Prevents dead batteries• Extends battery & starter life

INSTALL OUT LINE1. Unpack your system & in speck all components & wiring.

2. Check wire color at each side of a connector to insure that they match.

3. Give your machine a good look over to in sure that it is in good working order before you start your install.

4. Some things you may want to make a note of before you start.

A. Normal cranking time to start.

B. Is there a fast idle option on machine & is it working ?

C. Can this machine be started in gear?

5. Next on the engine locate a port for your oil temp sender.

6. Look inside the cabin for a good location to mount you main control center.

7. Decide where you will run your wiring harness & separate wires running to different locations.

Step 1

Most tractors & machines will have a place in the dash, under it or in a toolbox or storage area.

If a location such as the ones listed above are not available, securely install the MCM in a protected location where it cant be easily kicked or damaged

Step 2

Next, attach the MCM to the machine using the screws and L-shaped brackets supplied in the Kit

Step 3

Connect the main wiring harness to the MCM connector using a 7MM driver.

Check to make sure that the main wiring harness and MCM connector bundle have not come into contact with sharp metal edges that could chafe/cut the wires or insulation.

Check the color of each wire on the control center side to see if it is a match on the other side of the connector.

Common Symptoms TAS Will Not Common Symptoms TAS Will Not Activate & Possible FixesActivate & Possible Fixes

1. TAS will not go active, led stays red.

• Possible Tilt Switch circuit open

• Possible Park Brake circuit open

• Possible RPM signal loss

• Quick Tests

a. With test light check for power at Park Brake wires on switch, or at back of TAS main control center. ( Wire color on module side are tan / tan & white ) Engine Off. If No power check Tilt switch wires at back of TAS control center ( wire color gray/ white & gray) If you find no power, find & repair open circuit. If power found, go to test two.

b. Start engine. At back of control center, check orange / white wire, for RPM input signal. With a digital volt meter on 10 volt ac scale you should read at least 3 volts AC. Yes: Replace TAS control center. No: find & repair lost RPM sig.
